Positioning and plugging in the computer Place your equipment on a sturdy, flat surface near a grounded wall outlet. (Your computer was designed to be placed on the floor to conserve desk space, but it can also be placed on any stable, flat surface.) Before you plug your Macintosh into a wall socket, carefully read all the setup instructions in this chapter. Then, before you connect any other equipment to your Macintosh, follow the instructions in this section to plug it in. The plug grounds the computer and protects it from electrical damage while you set up. When you are ready to begin, follow these steps: 1 Plug the socket end of the computer’s power cord into the recessed power socket (marked with the symbol ≤) on the back of the computer. 2 Plug the other end of the power cord into a three-hole grounded outlet or power strip. Power cord plug Power cord socket WARNING This equipment is intended to be electrically grounded. Your Macintosh is equipped with a three-wire grounding plug—a plug that has a third (grounding) pin. This plug will fit only a grounded AC outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact a licensed electrician to replace the outlet with a properly grounded outlet. Do not defeat the purpose of the grounding plug!

power cord. Make sure that at least one end of the power cord is within easy reach so that you can unplug the computer when you need to. Connecting a monitor You can connect many types of monitors (often called displays) to your Macintosh computer, including most standard monitors. See the Technical Information booklet that came with your computer for a complete list. This section contains instructions for connecting most types of monitors. You should also refer to the instructions that came with the monitor for any special instructions. IMPORTANT If you are connecting an Apple monitor that has built-in speakers or a microphone, you may need to install monitor software after you have set up and turned on your computer. Otherwise, you may not be able to use all the monitor’s features. See the instructions that came with the monitor for more information. Connecting the monitor power cord At minimum, monitors have two cords to connect: a power cord and a monitor cable. To connect the monitor power cord, follow these steps: 1 Place the monitor near the computer. Keep these considerations in mind: m Allow at least three inches for air circulation around the computer and monitor. m Make sure that the top of the screen is slightly below eye level when you’re sitting at the keyboard. m Position the monitor to minimize glare and reflections on the screen from overhead lights and windows. For further suggestions about positioning your computer equipment, consult “Arranging Your Office” in Appendix A (in the section on health-related information). 4 Chapter 1

On some monitors, the cord is already attached. 3 Plug in the monitor power cord. Some monitor power cords are designed to plug into the back of your computer. Some monitor power cords must be connected to a grounded electrical outlet, not to the computer. Check the information that came with the monitor. Monitor power cord Monitor power socket 5 Setting Up Your Computer

After you plug in the monitor power cord, you connect the monitor cable to the computer’s monitor port. Some monitors also include a cable called an Apple Desktop Bus (ADB) cable, which you connect between the ADB ports (marked with the V icon) on the monitor and the computer. To connect the monitor cable and the ADB cable, follow these steps: 1 Attach the monitor cable to the monitor. On some monitors, the cable is already attached. 2 Attach the monitor cable to the monitor port on the back panel of the computer. Monitor cable ™ Monitor port 6 Chapter 1

icon on the back of the computer and on the back of the monitor. Some monitors (such as this Apple Multiple Scan 20 Display) come with an ADB (V) cable that you can plug into the back of the monitor. The other end of this cable can be connected to your computer. This allows you to connect either a keyboard, mouse, or other ADB device directly into your monitor’s auxiliary ADB ports. Apple Desktop Bus (ADB) port V Auxiliary ADB ports 7 Setting Up Your Computer

The way you connect the mouse and keyboard depends on whether the keyboard has a built-in cable or a separate cable. Connecting a keyboard with a built-in cable 1 Plug the mouse cable into the recessed port on the back of the keyboard. The plug and the port are marked with the V icon (symbol). The positions of the port and icon on your keyboard may be different from those pictured. 2 If the front or side of your monitor has a port marked with the V icon, plug the keyboard cable into this port. Otherwise, plug the keyboard cable into the port marked with the V icon on the back of the computer. This cable plugs into the Apple Desktop Bus (ADB) port, marked with the V icon, on the back of the computer. Plug the mouse into the recessed port on the keyboard. The flat part of the plug should be pointing down, as shown here.

3 If you want to adjust the angle of the keyboard, lower its feet. Connecting a keyboard with a separate cable 1 Plug the mouse cable into the port on either side of the keyboard. Most right-handed people prefer to use the mouse with their right hand; most left-handed people prefer to use their left hand. Plug the mouse into the port on the side you prefer. The plug and the port are marked with the V icon (symbol). Align the symbols before you insert the plug. (The positions of the port and icon on your keyboard may be different from those pictured here.) ADB icon To adjust the angle of the keyboard, lower the feet until they snap into position.

on installing and working with software on your computer. You’ll probably want to purchase and install application program software to do specific kinds of work on your computer. Application programs let you, among other things, do word processing; create spreadsheets, databases, and graphics; play games, alone or with others; and explore the Internet. Your computer includes some basic application programs as well as other software. Some are preinstalled and ready for use. Others are optional; if you want to use them, you must install them first. This chapter explains how to install and use application programs, and describes the software that came with your computer. 3 Installing and Using Software

Most application programs come with an installer that makes it easy to install them on your hard disk. Follow the instructions in the manuals that came with the specific programs to install them. Refer to the general instructions below for additional help on how to use the programs with the Macintosh operating system (Mac OS). If you have a virus protection program installed, you should turn it off before you install an application program. Also, use the Extensions Manager to turn off system extensions. For more information about Extensions Manager, see “Checking Your System Extensions” in Chapter 11, “Diagnostic Techniques.” In most cases, you’ll install an application program on your internal hard disk from a CD-ROM disc that contains the program. The illustration below shows how to insert a CD-ROM disc into your computer’s CD-ROM drive, the disc lying flat with the label side up. Some application programs come on floppy disks. The illustration below shows how to insert a floppy disk. Insert the floppy disk, metal end first, into the floppy disk drive of your computer. 32 Chapter 3

instructions that came with the program to install it. To eject a floppy disk or CD-ROM disc after installation is complete, click the disk icon to select it and choose Put Away from the File menu. IMPORTANT Never copy an entire CD-ROM disc to your hard disk. (Don’t drag the disc’s icon to your hard disk.) Copying the CD-ROM disc itself can take up a substantial amount of space on your hard disk. When you open programs on some CD-ROM discs, you may get a message telling you to copy or install the program onto your hard disk. If you get this message, refer to the installation instructions that came with the CD-ROM disc, or double-click the CD-ROM disc’s icon to open it, and then copy the CD-ROM disc’s program to your hard disk. Installing programs over a network If your computer is connected to a network, there may be application programs available on the network that you can install. Though you can run installer programs over a network, it is usually faster to first copy the program and its installer onto your computer, and then run the installer to complete the installation. Carefully read any Read Me file or other instructions you find with the program you want to install. 33 Installing and Using Software

You open a program the same way you open other items—by double-clicking the program’s icon. When you open a document, the program that created it opens automatically. Once you are working in a program, you can open other documents in that program by opening the File menu and choosing Open. Working with several programs at a time You can open as many application programs and desk accessories as your computer’s random-access memory (RAM) allows. The Application menu in the top-right corner of the screen lists the programs you have open. The name of the active program (the one you’re using right now) has a checkmark next to it, and its icon appears in the menu bar. Finding out which programs are open If you have several programs and windows open, you can find out which program is active and which other programs are open by opening the Application menu. 34 Chapter 3 A checkmark indicates the active program. Commands to hide or display open windows Open programs Application menu (The icon changes to show the active application.)

Application menu. If a program’s icon is dimmed in the menu, that means its windows are hidden. Choosing the program from the Application menu displays its windows. You can also switch to another program by clicking in a window that belongs to an open program or by double-clicking a program icon (or the icon of a document that was created with the program). Hiding and showing windows on the desktop You can hide all windows except those of the active program by choosing Hide Others from the Application menu. The other programs remain open even though their windows are hidden. When you switch to another program, its windows become visible again. You can hide the active program by choosing the menu item that has “Hide” next to the program’s name in the Application menu. For example, if the Finder is active, you can hide it by choosing Hide Finder from the Application menu. If you want to see all the open windows, choose Show All from the Application menu. 35 Installing and Using Software

Use “native” Power Macintosh programs. m Your Power Macintosh is compatible with most application programs intended for use with Macintosh computers. But it’s best to use Power Macintosh programs—sometimes called “native” programs—that are designed especially to take advantage of your computer’s PowerPC™ microprocessor. Put only one copy of each program on your hard disk. m Having more than one copy can cause errors. If you experience problems with a program, try reinstalling. m If a program malfunctions consistently, try installing a fresh copy. If that doesn’t help, find out from the software manufacturer whether your version of the program is compatible with the hardware and system software you’re using. Don’t install additional System Folders. m Whenever you copy a program disk to your hard disk, be careful not to copy another System Folder. Your startup disk should only contain one System Folder. Drag any extra System Folders to the Trash. Use virtual memory. m If you run out of memory while using Power Macintosh programs, you can use space on your computer’s hard disk as additional memory (called “virtual memory”). For instructions, choose Macintosh Guide (or Mac OS Guide) from the Guide (h) menu and read the information under “memory” in the Guide’s index. You can also add more memory to your computer, as described in Chapter 8, “Installing PCI Expansion Cards and Additional Memory.” 36 Chapter 3 1 2 3 4 5

Your computer includes a lot of software. Some of it is preinstalled and ready for use, while other software must be installed before you can use it. The types of software that come with your computer include m Mac OS operating system software m Optional system software additions m Application programs The following sections provide details about the included software. Mac OS operating system software The Mac OS is the basic software that runs the computer itself. It tells the computer what to do when it starts up, keeps track of your documents, files, and other software, and helps your computer find out what devices—such as printers and network cables—are attached to it. The Mac OS was installed on the internal hard disk at the factory, and starts automatically when you turn on your computer. Here is some of the software that comprises the Mac OS: m The Finder, which displays the desktop and allows you to organize documents, files, and application programs into folders m PC Exchange, which lets you work with DOS and Windows disks as if they were Mac OS disks m QuickTime, which lets you play digital video on your computer m AppleScript, which allows you to automate tasks in the Finder and other scriptable applications (applications that support AppleScript). Instructions for using AppleScript are in the Apple Extras folder on your hard disk. m ColorSync, which helps make sure that the colors you see on your monitor closely match the colors you get on printers, scanners, and other devices. For more information about ColorSync, see Macintosh Guide (or Mac OS Guide), available in the Guide (h) menu. IMPORTANT System software is preinstalled on your computer. Do not reinstall system software unless you are experiencing problems or you want to upgrade to a more recent version. Consult Chapter 11, “Diagnostic Techniques,” before attempting to reinstall system software. 37 Installing and Using Software

Your computer includes optional software that adds other capabilities to the Mac OS. This software was not installed at the factory, so you have to install it if you want to use it. Tip: Some of this software can decrease the amount of memory available for use by programs. To conserve memory, only install the software you think you’ll use. These are some of the optional system software additions included with your computer: m OpenDoc, which extends the usefulness of your applications by adding new functionality in the form of self-contained software components, or “parts.” A variety of parts will be available from both Apple and third- party sources, including parts for placing Internet resources directly into documents. m QuickDraw GX, which gives your computer more powerful printing capabilities m QuickDraw 3D, which gives your computer the ability to display graphics in three dimensions m PlainTalk, which allows your computer to understand spoken commands in English and Mexican Spanish m Apple VideoPhone software, which allows you to set up video conferences and collaborate over a network To see what is included with your computer, look in the Apple Extras folder on your hard disk and in the CD Extras folder on the CD-ROM disc that came with your computer. There is usually a Read Me file that explains each system software addition in more detail. To install one of these items, look for an Installer icon, similar to the one below, for the software. Double-click the Installer and follow the instructions that appear. 38 Chapter 3

play audio CDs in your CD-ROM drive, and to open HyperCard stacks. It also includes Internet access programs such as the Apple Internet Connection Kit. To see what’s available, look on your hard disk and on the CD-ROM disc that came with your computer. Some of the programs are preinstalled, while others must be installed before you can use them. To install one of these items, look for an Installer icon for the program. Double-click the Installer and follow the instructions that appear. If you have questions about using an application program, refer to the Read Me file for the program, which is usually found inside the program’s folder. Some programs also have online help that you can access after you have installed the program. Look for online help in the Guide (h) menu after you start the program. For more information about the Apple Internet Connection Kit, see Chapter 6, “Using an Online Service or the Internet.” Backing up your files Making backup copies of important files is good protection against possible damage to the originals. m You can back up files stored on your hard disk by copying them to floppy disks. m You can back up an entire floppy disk by copying it to another floppy disk of the same capacity or larger, or by copying it to a hard disk. m You can use a commercial backup program to copy new and changed files from a hard disk to another hard disk, a tape drive, a series of floppy disks, or to another form of removable media. m If your computer is on a network, you may be able to back up files by copying them to a shared disk on the network. 39 Installing and Using Software

Chapter 5 Connecting Your Computer to a Network Chapter 6 Using an Online Service or the Internet Communicating With Other Computers

to a telephone line, you can access the Internet, send and receive electronic mail (“e-mail”) and faxes, and connect to online services like America Online and CompuServe. You can also use a telephone line to access another Macintosh or an entire AppleTalk network from a remote Macintosh computer. (For example, you can telecommute by accessing a company computer network from a remote location, such as a home office.) To get online, you need special equipment and software. This chapter provides a brief introduction to the equipment you need. For information about the software you need to perform online tasks, see Chapter 6, “Using an Online Service or the Internet.” Read this chapter for information about the equipment you need to get online, such as modems and ISDN lines. 4 Connecting Your Computer to a Telephone Line

There are three types of equipment you can use to get online: a modem, an ISDN line, and shared telecommunications equipment on your network. Modem: A modem may be the most common way to connect a computer to a phone line, particularly if you are using your computer at home. A modem works with standard analog telephone lines. For more information about modems, see the next section, “Choosing and Connecting a Modem.” ISDN line: An Integrated Services Digital Network (ISDN) line is a special digital phone line that is about four times faster than the fastest modem used over a standard analog telephone line. However, an ISDN line typically costs more than regular phone service and may not be available in your community. For more information about ISDN, see “Connecting to an ISDN Line” later in this chapter. Shared telecommunications equipment on your network: One of the advantages of networks is that you can share equipment, such as printers and file servers. If your computer is one of many linked together in a network, there may also be shared communications equipment connected to your network that will allow you (or anyone else on your network) to get online. Contact your computer network administrator for more information. You can also find general information about networks in Chapter 5, “Connecting Your Computer to a Network.”

A modem is a piece of equipment that turns the data from your computer into information that can be transmitted over telephone lines. The modem enables your computer to send and receive telephone calls, to connect to the Internet, to access online services, and to communicate with other computer users. Some modems also allow you to transmit documents on your computer to fax machines as well as receive faxes as documents that you can view on screen or print. Keep in mind that when your phone and a modem share a single phone line, you will not be able to use both at the same time, even if they are attached to separate phone jacks. While you use a modem, outside callers get a busy signal and you cannot call out. Conversely, when you use your phone, you cannot use the modem. (If you miss phone calls because you often use your modem, you may want to get a second phone line installed or get a phone company message service which, unlike an answering machine, will record messages even when your phone is off the hook or you are online.) Also keep in mind that long-distance charges accrue when your modem dials long-distance numbers. In most cases, an online service or an Internet service provider will have a local access phone number so that long-distance charges do not apply. 45 Connecting Your Computer to a Telephone Line

When selecting a modem, look for one with fast data-transfer speed, a compatible modem cable, and good bundled software. Data-transfer speed The data-transfer speed determines how fast a modem can move data between your computer and other computers. Purchase the fastest modem that you can afford, particularly if you plan to connect to the World Wide Web. Many Web pages contain graphics, video, and sound files that will take longer to download (copy onto your computer) with a slower modem. The data-transfer speed of a modem is specified in kilobits per second (kbps) or bits per second (bps). Faster modems transfer data to and from your computer more quickly than slower ones. The following table describes the current modem speeds that are available. Modem speed Usage 33,600 bps The fastest modem available (as of this writing) for use with standard (33.6 kbps) analog telephone lines. Suitable for World Wide Web use. 28,800 bps Slightly slower than a 33.6 kbps modem, but still very suitable (28.8 kbps) for World Wide Web use. 14,400 bps Only half as fast as a 28.8 kbps modem. May be acceptable for (14.4 kbps) text-oriented applications such as e-mail or terminal emulation. 9600, 4800, Too slow for most purposes. and 2400 bps Modem cable If you purchase a modem that is designed for use with a Macintosh, it will probably include a Macintosh-compatible modem cable. If you have to purchase a cable separately, make sure it supports hardware handshaking, a protocol that controls the flow of data between computers. Also, check to make sure the cable has a rounded connector that will fit the modem port on the back of your computer (labeled with a W icon). A cable designed for use with a Windows- or DOS-compatible computer won’t work with your Macintosh. 46 Chapter 4

emulation program, and free trial membership software for online services. If you can’t decide between two comparatively priced modems, pick the one that comes with the best bundled software. Connecting a modem To connect a modem, follow the instructions in the manuals that came with your modem. Note: Some modem models have a single phone jack, while others have two. If your modem has only one phone jack, consider purchasing a line splitter at an electronics supply store. A line splitter enables you to plug your phone and your internal modem into the same jack at the same time. (By the way, you can keep your answering machine connected to your phone, even if your phone and modem share the same telephone line.) IMPORTANT When connecting a modem, make sure you connect the modem to an analog phone line—the kind used typically in homes. Connecting to an ISDN line could damage the modem. IMPORTANT Disconnect your modem from the phone jack during lightning storms. This will prevent a destructive voltage overload from damaging the modem. Connecting to an ISDN line If you have a home office, telecommute frequently, or routinely need to send and receive large files, then a 28.8- or 33.6-kbps modem may not be fast enough for your needs. For faster performance, you may want to consider connecting your computer to an Integrated Services Digital Network (ISDN) digital telephone line, which can transfer data at 128 kbps, nearly 4.5 times faster than a 28.8-kbps modem. ISDN lines are available to most but not all residential and business telephone customers. Check with your local phone company to see if ISDN service is available at your location. 47 Connecting Your Computer to a Telephone Line

regular phone service. Typically, ISDN costs more than regular phone service, but it is still affordable for many business and residential purposes. Because one ISDN line can support several devices simultaneously—such as a computer, voice phone, and fax machine—you may be able to replace existing extra phone lines with one ISDN line. Note: Because an ISDN line requires a power source at your location, a phone attached to an ISDN line will not work during a power outage. For emergency use, you should strongly consider keeping your regular analog phone line, which receives power from the phone company. Setting up an ISDN line If you’re interested in setting up an ISDN line, first contact your local phone company to see if ISDN service is available at your location. Your phone company can also provide specific information about monthly charges and usage fees. (Your phone company may also charge an installation fee, which may be waived or refunded if you agree to keep the ISDN line for a specified amount of time.) In addition, you also need to purchase and configure an ISDN terminal adapter, which connects to the external modem port on your Macintosh and to the ISDN line. (ISDN terminal adapters are often called “ISDN modems” because they are somewhat similar to modems.) Some ISDN terminal adapter models may be difficult to configure with the network configuration of your employer or Internet service provider (ISP). Work closely with your computer network administrator or ISP to make sure you purchase a compatible ISDN terminal adapter. 48 Chapter 4

network that consists of as few as two computers or as many as thousands or even millions of computers and other devices. The network allows you and the other people connected to it to share information, access remote services, and share computing resources such as printers and modems. A network extends the features of your Macintosh by extending your reach to the services and resources provided on the network. For example, by itself, your computer lets you store, retrieve, and modify information on hard disks and floppy disks. On a network, however, you can also store and retrieve information on servers, access information that other people have stored on their computers, and use electronic mail and other network services. You can connect your Macintosh to a LocalTalk network and to a high-speed Ethernet network. You can also purchase peripheral component interconnect (PCI) cards for alternative networks such as TokenRing, ISDN, and Fiber Distributed Data Interface (FDDI). 49 5 Connecting Your Computer to a Network Read this chapter for information on physically connecting and configuring your computer to work on a network.

LocalTalk and Ethernet networks. Refer to the appropriate information source for other network-related information: m If your computer is already connected to a network, refer to Macintosh Guide (or Mac OS Guide), available in the Guide (h) menu, for information about printing on a networked printer, accessing information on file servers, and sharing files on your computer with other users. Also, your network administrator can provide information about network software that may be available, such as Internet access and electronic mail. m If your location does not currently have a network and you are interested in setting one up, you should refer to a book on Macintosh networking that will help you select and plan a network that is appropriate for your organization. Many books are available, such as Planning and Managing AppleTalk Networks, an Apple book published by Addison-Wesley that is available at computer bookstores. 50 Chapter 5

Connecting to a LocalTalk network To connect your Macintosh to a LocalTalk network, you will need LocalTalk cables and a LocalTalk adapter. In most cases, the Apple LocalTalk Locking Connector Kit DIN-8, available from your Apple-authorized dealer, contains the components you need to connect your Macintosh to an existing LocalTalk network. If your network uses standard telephone cables for your network wiring, obtain an Apple LocalTalk RJ-11 Connector instead. Note: At your location, there may be a network administrator who is responsible for network maintenance and upkeep. If so, ask your network administrator to help connect your computer to the network. To connect your Macintosh to a LocalTalk network, do the following: 1 Shut down your Macintosh. 2 Attach the LocalTalk adapter to the printer port on your computer. Printer port icon Printer port LocalTalk adapter LocalTalk adapter Apple LocalTalk RJ-11 Connector Apple LocalTalk Locking Connector Kit DIN-8 LocalTalk cable Standard telephone cable

the last LocalTalk adapter on your existing network. Use the LocalTalk cable that comes with the Apple LocalTalk Locking Connector Kit DIN-8. Use a standard telephone cable with RJ-11 connectors if you are using the Apple LocalTalk RJ-11 Connector. Next, see “Configuring Your Network Connection” later in this chapter for information on configuring your LocalTalk connection. Printer port LocalTalk adapter LocalTalk cable 52 Chapter 5

The built-in Ethernet capabilities of your Macintosh allow you to connect to any standard Ethernet network using 10Base-T twisted-pair cables, thin or thick coaxial cables, fiber-optic media, or other standard Ethernet cables. You can connect directly to an Ethernet network that uses 10Base-T twisted- pair cable. To connect your Macintosh to an Ethernet network that uses coaxial cables, you need one of the following Ethernet media adapters: m Apple Ethernet Thin Coax Transceiver m Apple Ethernet AUI Adapter See your Apple-authorized dealer for more information on Apple Ethernet media adapters. Refer also to the following instructions for information on which items to purchase. You can connect an adapter and cable for an Ethernet network directly to the computer without installing an expansion card. You can find the Ethernet ports on the back of your Macintosh by looking for the Ethernet icon: Although you can connect cables to both of these Ethernet ports at the same time, only one of the ports will be active. For more information, see “Connecting to Multiple Networks Simultaneously” later in this chapter. Note: At your location, there may be a network administrator who is responsible for network maintenance and upkeep. If so, ask your network administrator to help connect your computer to the network. AAUI Ethernet port Ethernet icon 10Base-T Ethernet port WARNING Do not connect cables to the back of your computer when the computer is on or you may damage your system. 53 Connecting Your Computer to a Network

Follow this procedure to connect your Macintosh to an Ethernet network that uses twisted-pair cable. The hardware connection requires a twisted-pair patch cord with an RJ-45 telephone-style connector. You plug the patch cord into a wall plate that is connected to a centralized 10Base-T hub. To connect your Macintosh to a twisted-pair Ethernet network: 1 Shut down your Macintosh. 2 Plug one end of the twisted-pair patch cord into the 10Base-T Ethernet port on your Macintosh. 3 Plug the other end of the twisted-pair patch cord into an RJ-45 wall outlet that is connected to a twisted-pair Ethernet network. Next, see “Configuring Your Network Connection” later in this chapter for information on configuring your network connection. Connecting to a thin coaxial Ethernet network Follow this procedure to connect your Macintosh to an Ethernet network that uses thin coaxial cable. The hardware connection requires an Apple (or Apple-compatible) thin coaxial transceiver and a thin coaxial cable. Ethernet port (10Base-T) 3-meter patch cord Wall plate 10Base-T hub 54 Chapter 5

however, to do so requires that you temporarily disconnect the network, which could disrupt existing network services and other people using the network. Consult your network administrator before connecting your computer to the network. To connect your Macintosh to a thin coaxial network: 1 Shut down your Macintosh. 2 Attach one end of a thin coaxial cable to the last thin coaxial transceiver on the network. 3 Attach the other end of the thin coaxial cable to one of the connectors on the thin coaxial transceiver. 4 Plug the connector on the transceiver into the AAUI Ethernet port on your Macintosh. A thin coaxial network must be terminated at the endpoints to function. An Apple transceiver is self-terminating. A non-Apple transceiver may require a terminator; check the documentation that came with the transceiver. Next, see “Configuring Your Network Connection” later in this chapter for information on configuring your network connection. Ethernet port (AAUI) Ethernet thin coaxial transceiver Thin coaxial cable 55 Connecting Your Computer to a Network

The Apple Ethernet AUI Adapter is a universal adapter that lets you connect your Macintosh to less-common types of industry-standard Ethernet media, such as thick coaxial or fiber-optic cable. If you are using the Apple Ethernet AUI Adapter, you also need an Ethernet transceiver for your specific media type; the transceiver must have a standard AUI port on it. To connect your Macintosh to an Ethernet transceiver for other types of Ethernet media: 1 Shut down your Macintosh. 2 Connect the Ethernet transceiver to the network following the instructions that came with the transceiver. 3 Plug the transceiver cable from the Ethernet transceiver into the standard AUI port on the Apple Ethernet AUI Adapter.

5 Plug the connector on the Apple Ethernet AUI Adapter into the AAUI Ethernet port on your Macintosh. Next, see “Configuring Your Network Connection” later in this chapter for information on configuring your network connection. Connecting to multiple networks simultaneously Because your Macintosh has three networking ports—LocalTalk, AAUI Ethernet, and 10Base-T Ethernet—it is possible to be physically connected to more than one kind of network at the same time. However, you can use only one of your connections at one time. If both 10Base-T and AAUI networks are connected, your Macintosh automatically uses the 10Base-T connection. You cannot use the AAUI connection unless you physically disconnect the 10Base-T connection. If you are connected to both a LocalTalk and an Ethernet network (either 10Base-T or AAUI), your computer uses the Ethernet connection unless you specify LocalTalk in the AppleTalk control panel. “Configuring Your AppleTalk Network Connection” in the section “Configuring Your Network Connection” (next) explains how to specify the port you want to use. 57 Connecting Your Computer to a Network

After you physically connect your computer to a LocalTalk or Ethernet network, you need to configure your network connection in the AppleTalk control panel, the TCP/IP control panel, or both. You use the AppleTalk control panel to set up your connection to an AppleTalk network (that is, a network using the AppleTalk protocol). You use the TCP/IP control panel to set up your connection to the Internet and to a TCP/IP network. TCP/IP stands for Transmission Control Protocol/Internet Protocol, a standard system for connections between computers of different types. You may need additional information about the network to which your computer is connected, or about the service through which your computer is connected to the Internet. To get this information, you may need to contact your network administrator or your Internet service provider. 58 Chapter 5

To configure your AppleTalk network connection, you must specify the port you use to connect your computer to the network. Larger networks use zones to create logical groupings of computers, printers, servers, and other network devices. For example, a network might have a zone for each floor in a multistory office building. If your network has more than one zone, you can choose the zone in which your computer is located. The zone you choose is the zone that is automatically selected in the Chooser (for example, when you select a network printer) and it is the zone in which other network users can find your computer if you turn on file sharing. To configure your AppleTalk network connection, follow these steps: 1 Choose Control Panels from the Apple (K) menu. 2 Double-click the AppleTalk icon to open it. The AppleTalk control panel opens. 3 Use the “Connect via” pop-up menu (if available) to choose the port through which your computer is connected to the network. You can connect to an AppleTalk network through an Ethernet port, the printer port, the modem port, or any additional ports available on expansion cards installed in your computer. (Any additional ports appear automatically in this pop-up menu.) Note: If you don’t see a pop-up menu here, this setting has been locked. Contact your network administrator for assistance. (If you don’t have a network administrator, you can use the Administration user mode to unlock this setting. For more information about user modes, click the h button in the AppleTalk control panel.) 59 Connecting Your Computer to a Network

If you don’t see a pop-up menu here, this setting has been locked or your network is not set up to allow you to choose a zone. Zones are set up by the network administrator. 5 Click the close box to close the AppleTalk control panel. If you have made configuration changes, an alert box asks if you want to save them. If you have changed the port, an alert box also tells you that the change will interrupt any AppleTalk services that are established. This means that your network services such as printers and e-mail may be temporarily unavailable, and you may have to choose a printer and log on to your e-mail again after saving changes. 6 To save your changes, click the Save button. Your changes take effect immediately; you do not have to restart your computer. Getting more information about the AppleTalk control panel Macintosh Guide (or Mac OS Guide) contains information about additional capabilities available in the AppleTalk control panel, such as: m using configurations, a way to save different AppleTalk settings and switch among them as desired—for example, if you use your computer with more than one network m using the User Mode command to change the availability of settings in the AppleTalk control panel m turning AppleTalk off in order to save RAM in your computer when you are not using an AppleTalk network For more information about these capabilities, click the h button in the AppleTalk control panel. 60 Chapter 5

You use the TCP/IP control panel when your computer is connected to a network that uses TCP/IP standards, such as the Internet. TCP/IP (Transmission Control Protocol/Internet Protocol) is a standard set of rules (or protocols) for making connections among different types of computers. TCP/IP protocols can be used with many different types of network hardware, including LocalTalk, Ethernet, and dialup Internet connections. If you don’t know whether your network uses TCP/IP, contact your network administrator. To set up your TCP/IP network connection, you must specify the port you use to connect your computer to the network. TCP/IP networks also require information about your computer’s network address. You must enter that information in the control panel, or specify a server on which the information can be found. Before you begin To use a TCP/IP network, your computer must have an IP (Internet Protocol) address, and it often must have a subnet mask number. Your network address and subnet mask number identify your computer’s location on the network. This information can be entered manually or obtained automatically from a server. Before you set up your TCP/IP network connection, obtain your IP address and subnet mask number from your Internet service provider or network administrator. If these can be obtained automatically from a server, find out whether the server is a “BootP,” “RARP,” “DHCP,” or “MacIP” server. “BootP” stands for Boot Protocol. A BootP server can automatically provide all the TCP/IP setup information you need. “RARP” stands for Reverse Address Resolution Protocol. A RARP server can provide the IP address for your computer, but you must provide the rest of the information manually. “DHCP” stands for Dynamic Host Configuration Protocol. A DHCP server can automatically provide all the TCP/IP setup information you need. 61 Connecting Your Computer to a Network

and a protocol for sending Internet-type packets of information over an AppleTalk network. A MacIP server can provide all the TCP/IP setup information you need, but you need to know the zone where the MacIP server is located. Setting up To set up your TCP/IP network connection, follow these steps: 1 Choose Control Panels from the Apple (K) menu. The Control Panels window opens. 2 Double-click the TCP/IP icon to open it. The TCP/IP control panel opens. 3 Use the “Connect via” pop-up menu to choose the port through which your computer is connected to the network. Note: If you don’t see the pop-up menu here or other settings described in this section, they may have been locked. Contact your network administrator for assistance. (If you don’t have a network administrator, you can use the Administration user mode to unlock this setting. For more information about user modes, click the h button in the TCP/IP control panel.) 62 Chapter 5

If you are connected using Ethernet, the pop-up menu looks like this: If you are connected using AppleTalk (MacIP), the pop-up menu looks like this: What you do next depends on whether you are configuring your network manually or automatically. 5 If you are configuring your network connection manually, type the information provided by your network administrator or Internet service provider into the appropriate boxes. You must specify an IP address. You may also need to enter a subnet mask number, router address, and other information. 6 If you are configuring your network connection automatically, do one of the following: m If you are using a BootP server or DHCP server, skip ahead to step 7. The server usually provides all the configuration information needed by TCP/IP. m If you are using a RARP server, you may need to type additional information provided by your network administrator or Internet service provider into the appropriate boxes. If so, enter the information now. m If you are using a MacIP server, click Select Zone. In the dialog box that appears, choose the zone that contains the MacIP server you want to use and then click OK. 63 Connecting Your Computer to a Network

If you have made configuration changes, an alert box asks if you want to save them. If you have changed the port, an alert box also tells you that the change will interrupt any TCP/IP services that are established. For example, you may have to quit and reopen a Web browser or e-mail software after saving changes. 8 To save your changes, click the Save button. Your changes take effect immediately; you do not have to restart your computer.

the online community. By connecting your computer to an online service or the Internet, you can exchange electronic mail (“e-mail”) messages, gather information on topics of interest, participate in discussion groups, download software, and use many other services. Your Macintosh computer includes software that you can use to connect to an online service or the Internet. This chapter describes the software and provides a brief introduction to the information and services that are available online. In addition to the included software, you need special equipment, such as a modem, to get online. For more information about the equipment you need, see Chapter 4, “Connecting Your Computer to a Telephone Line.” Connection software Your Macintosh comes with two different application programs that you can use to get online: America Online and the Apple Internet Connection Kit. Although both programs provide Internet access, they have different features; you can use the one that best addresses your needs. Read this chapter for information about the Internet and online services software that is included with your computer. 6 Using an Online Service or the Internet

America Online provides many exclusive information services that may not be available on the Internet. AOL is also very easy to use, and may be the best choice if you have never used an online service or the Internet before. For more information about AOL, see its folder on your hard disk or on the CD that came with your computer. Apple Internet Connection Kit The Apple Internet Connection Kit is a collection of Apple and third-party software that lets you connect to the Internet quickly and easily. The kit includes the Netscape Navigator Web browser, Claris Emailer Lite e-mail software, and several other Internet applications and utilities. For more information, see the Apple Internet Connection Kit: Getting Started manual that came with your computer. If you decide to use the kit, your best source of help is the Apple Internet Connection Kit Guide, available in the Guide (h) menu when you’re using the kit’s software. Note: To connect to the Internet by modem using the Apple Internet Connection Kit, you need an Internet service provider (ISP). You pay the ISP to use their access to the Internet, much as you pay the phone company for access to the telephone network.

You can usually do the following through an online service or the Internet. Exchange electronic mail You use e-mail to exchange messages. You can create, read, and respond to e-mail. Unlike paper mail, you can conveniently send the same e-mail message to a group of recipients. You can also subscribe to e-mail distribution lists that provide information on topics of interest to you. Access the World Wide Web The World Wide Web is the fastest growing part of the Internet. Many organizations post information on Web “pages” that you can view with software called a Web browser. A portion of the Apple Computer “home page” is shown below. A Web page usually contains words or pictures that serve as links to other information; you click these links to display related information. There are Web pages available on every imaginable subject, providing news, information, and entertainment. You can search the Web to find information on topics of interest. Some online services and companies that provide Internet access will even set aside some space for you to make your own Web page available. 67 Using an Online Service or the Internet

application software at a minimal cost (and often at no cost at all). Although Apple Computer, Inc., does not provide technical assistance with non-Apple software you download, the software’s creators may provide technical support. Join a discussion group Discussion groups are forums where people with common interests openly exchange information by writing messages. On the Internet, these discussion groups are called Usenet newsgroups. Like Web pages, Usenet newsgroups address nearly every subject imaginable. Topics range from stamp collecting to nuclear physics to cooking. 68 Chapter 6

Your computer has two sets of ports (also known as “jacks”) for handling audio equipment: sound input and output ports like those found on most models of Macintosh; and left and right RCA-type input and output ports. The sound input and output ports Your Macintosh can handle stereo sound from a sound input device—also called a sound source—such as a microphone, tape deck, or audio CD player. (If you have an internal CD-ROM drive, it can also be used to play audio CDs.) The term “sound input device” is used because the signal goes into your computer for you to record or process in various ways. Sound input devices can be attached to the sound input port, which is marked with an icon of a microphone (≈). Your computer comes with a built-in speaker, but you can attach an additional sound output device, such as amplified speakers or headphones. Sound output devices can be attached to the sound output port, which is marked with an icon of headphones (f) or a speaker (-). ≈ Sound input port - Sound output port 76 Chapter 7

connectors: The “stereo miniplug” is the smaller of the two and is found most often on stereo equipment. The extended miniplug, which is slightly longer and is found on voice quality microphones (such as the Apple PlainTalk Microphone), works only in your computer’s sound input port (≈). (Even though it will fit into the sound output port, it won’t work there.) If your equipment has a different type of connector from those shown here, you can purchase an adapter at an electronics supply store. The left and right RCA-type audio ports Your computer also has ports that accept left and right input and output through RCA-type connectors. These connectors are found on devices like videocassette recorders (VCRs) and tape decks. The RCA ports are color- coded to help you properly attach your audio equipment.

You can connect video equipment to your computer so that you can view TV and other video images on your monitor, and store the images on your hard disk. You can also view the Macintosh desktop on a television screen attached to the computer, and record images from the desktop using a videocassette recorder (VCR). Your Macintosh can work with two major video formats: m Composite video, which is used by most televisions, most VCRs, and laserdisc players. Composite video devices plug into the computer’s RCA-type video ports (˜ and Â) m S-video, which is a high-quality video format used by many video cameras, VCRs, and televisions. S-video devices plug into the computer’s S-video ports (æ and Æ). The video input and output ports and connectors The illustration below shows the computer’s video input and output ports.

Using a television and a monitor together The amount of video random-access memory (VRAM) determines whether you can view the desktop simultaneously on both a television and the computer monitor. If your computer is equipped with 4 megabytes (MB) of VRAM, you can connect a television and a computer monitor simultaneously and view the desktop on both the monitor and the television. If your computer is equipped with 2 MB of VRAM, you can only view the desktop on either the monitor or the television. When you start up your computer with both a monitor and a television connected, the desktop will appear on the monitor, and the television screen will be dimmed or black. To use a television as the only monitor, shut down your computer and disconnect the computer monitor. Then turn on the television and then start up the computer. For further instructions on using a television as a monitor, choose Macintosh Guide (or Mac OS Guide) from the Guide (h) menu; click the Guide’s Index button, and choose “video” from the index.

Your computer has a port for connecting devices that use the Small Computer System Interface (SCSI, pronounced “skuh-zee”). SCSI is a standard method for connecting disk and cartridge drives, CD-ROM drives, scanners, and other devices. The SCSI port permits high-speed communication between the computer and the device. The SCSI icon appears above the port on the computer’s back panel. You can connect SCSI devices to the SCSI port in a chainlike fashion. The first device in the chain plugs into the SCSI port; the second device plugs into the first device, and so on. You can attach up to seven SCSI devices in the chain. Each device on the SCSI chain must have a unique ID number. Note: In addition to the external SCSI port, your computer has a separate, internal SCSI interface for the internal hard disk, CD-ROM drive, and Zip drive. An authorized Apple dealer or service provider can install and attach additional devices to the internal SCSI interface. For more information about the internal SCSI interface, see the Technical Information booklet that came with your computer. SCSI port SCSI icon 93 Connecting Additional Equipment

Before you connect a SCSI device to your Macintosh, be sure to complete the tasks explained in this section. IMPORTANT This section contains general instructions for attaching SCSI devices to your computer. Be sure also to follow the specific instructions that came with your external hard disk drive or other SCSI device when connecting the device to your Macintosh. The specific instructions that came with the device tell how to change a device’s ID number and attach a SCSI cable or terminator to it. Make sure each device has a unique ID number Each external SCSI device connected to your computer must have its own, unique ID number from 0 to 6. The SCSI ID number helps the computer keep track of the devices and sort out conflicts when more than one device in the SCSI chain is communicating with the computer simultaneously. The SCSI devices can be in any physical order in the chain; it is not necessary to arrange them in numerical order. See the instructions that came with each SCSI device for information on checking and setting its SCSI ID number. IMPORTANT If you use two or more devices attached to the same SCSI interface with the same ID number, your computer will not start up properly, your equipment could malfunction, and you could lose data as a result. 94 Chapter 7

To attach a SCSI device to your computer or to another device in the chain, always use SCSI cables that are double-shielded, such as Apple SCSI cables. Never use printer-type RS232 cables (commonly used with DOS and Windows computers). Poor quality SCSI cables are often the cause of SCSI problems. Avoid mixing brands and types of SCSI cables. If the device is the first or only one you’re connecting, use a SCSI system cable to connect it to the computer’s SCSI port: If the device is not the first one, use a SCSI peripheral interface cable to connect it to the last device in the chain: IMPORTANT The total length of the cables in a SCSI chain should not exceed 6 meters (about 20 feet). SCSI cables must have a 110-ohm impedance. For best results, use SCSI cables manufactured by Apple Computer. Keep the cables between SCSI devices as short as possible. Cables 18 to 24 inches long are best. PowerBooks and some SCSI devices (particularly scanners) may not be able to handle cables longer than 24 inches. SCSI peripheral interface cable SCSI system cable 95 Connecting Additional Equipment

To ensure accurate transmission of information, a terminator must be present at each end of a SCSI chain. There is already a built-in terminator at the beginning of the chain. Therefore, you only need to make sure that the last device in the chain has a terminator. IMPORTANT In almost all cases, only the first and last devices in the SCSI chain should be terminated with the exceptions noted below. Make sure that no external SCSI device but the last one has a terminator. To terminate the last device in the chain, do one of the following: m Use a device that has a built-in terminator as the last device in the chain. If you wish to attach two or more SCSI devices that have built-in terminators, an Apple-authorized service provider can remove the extra built-in terminators. m If the device at the end of the SCSI chain does not have a built-in terminator, attach an external terminator. You can attach or remove external terminators yourself. (Do not use a black terminator; the black terminators are for Macintosh IIfx computers and certain LaserWriter printers only.) Terminators are available at authorized Apple dealers. Exceptions to the “first and last” rule: If the SCSI chain is 18 inches or shorter, the terminator on the last device is not needed. If the total cable length in the chain is greater than 10 feet, the chain may need a third terminator at the 10-foot point. Do not add the third terminator unless you are experiencing a SCSI problem, and check all other possible causes of the problem before adding the third terminator. External SCSI terminator 96 Chapter 7

After you read “Before You Connect a SCSI Device” earlier in this chapter, follow the instructions below. Use these general instructions in conjunction with the more specific instructions that came with your SCSI device. 1 Shut down your Macintosh. 2 Make sure the SCSI device is switched off. 3 Use a SCSI cable to connect the device either to the computer’s SCSI port or to the last SCSI device already in the chain. Use the thumbscrews and metal clips on the connectors to maintain a tight, reliable connection. Do not overtighten the thumbscrews. 4 Turn on all devices in your SCSI chain. IMPORTANT Always turn on all external SCSI devices connected to your Macintosh before turning on the computer itself. Otherwise, your computer won’t be able to recognize that the SCSI devices are connected to it and your computer may not be able to start up. 5 Install any necessary device drivers (software that makes a device work with your computer). Drivers needed for a SCSI device usually come on a floppy disk with the device. (If no drivers come with the device, contact the device’s manufacturer.) Note: If you experience problems after connecting a SCSI device, see the troubleshooting information in Chapter 10, “Solutions to Common Problems.” WARNING Do not connect or disconnect any device while the device or your Macintosh is turned on. Doing so could damage the device, your computer, or both. Do not attach or remove a terminator while the computer or any device is turned on. 97 Connecting Additional Equipment

Your computer has a printer port, which you use to connect a printer. The printer port accepts either a direct cable connection (to printers such as the StyleWriter 2500) or a network cable connection (to printers such as most LaserWriter models). A printer can also be connected to the modem port. See the manual that came with your printer for more detailed information and instructions on setting up and using the printer. Although your computer comes with most Apple printer software (called “printer drivers”) already installed, you may need to install software from disks that came with your computer. You use the Chooser to tell the computer which port you used to connect your printer. For instructions on choosing a printer, open the Guide (h) menu and choose Macintosh Guide (or Mac OS Guide), click the Guide’s Index button, and choose “printing” from the index. Printer port icon Printer port 98 Chapter 7

You can install an expansion card that provides a second monitor port, if one monitor doesn’t provide enough screen space. To connect a second monitor, purchase a video card and install it in one of the computer’s PCI expansion slots, or have an Apple dealer install it for you. (If you are installing the expansion card yourself, follow the instructions that came with the card and the instructions in Chapter 8 of this manual.) Then plug the second monitor into the port provided by the card. When you connect an additional monitor, make sure that the ventilation openings on the computer and the monitors are clear and unobstructed. If there is interference on your screens or on a television or radio near your computer, separate or reposition the affected equipment. You may need to increase the distance between two monitors so that they don’t interfere with each other. IMPORTANT Though it is possible to install additional video cards that supply more monitor ports, do not connect more than two monitors at a time to your computer. For additional instructions on using two monitors together, choose Macintosh Guide (or Mac OS Guide) from the Guide (h) menu after you have connected two monitors to your computer; click the Guide’s Index button, and choose “monitors” from the index. 99 Connecting Additional Equipment

Your computer has an Apple Desktop Bus (ADB) port, which connects the mouse and the keyboard to your computer. You can add other input devices, such as a bar-code reader, graphics tablet, or joystick. The ADB port is marked with the V icon. You can connect up to three ADB devices in a chainlike fashion to a single ADB port. The exact number depends on how much power the devices require. Before you attach or remove an ADB device, turn off the computer. Attaching or removing an ADB device while the computer is turned on could damage the ADB device or your computer. IMPORTANT The total power used by all ADB devices connected to your computer must not exceed 500 milliamperes (mA). Before attaching another ADB device, check the Technical Information booklet that came with your computer and the information that came with the ADB device for power requirements.
