If you are viewing this documentation on your computer, click the blue text to jump to the linked item. NOTE: A Note indicates important information that helps you make better use of your computer. ! CAUTION: A Caution indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. Introduction to Wireless Networking An AP extends the capability of an existing Ethernet network to devices on a wireless network. Wireless devices can • connect to a single Access Point, or • move between multiple Access Points located within the same vicinity. As wireless clients move from one coverage cell to another, the devices maintain network connectivity.

Avaya Wireless AP-4/5/6 User’s Guide 1-3 Site Survey To determine the best location for an Access Point, Avaya recommends conducting a Site Survey before placing the device in its final location. For information about how to conduct a Site Survey, contact your local reseller. Before an Access Point can be configured for your specific networking requirements, it must first be initialized. See Getting Started for details. Figure 1-1. Typical wireless network access infrastructure

1-4 Avaya Wireless AP-4/5/6 User’s Guide Once initialized, the network administrator can configure each unit according to the network’s requirements. The AP functions as a wireless network access point to data networks. An AP network provides: • Seamless client roaming • Easy installation and operation • Over-the-air encryption of data High speed network linksTo be fully operational, the AP-3 needs at least one wireless card installed. Guidelines for Roaming Wireless Standard Support An AP can only communicate with client devices that support its wireless standard. For example, an 802.11a client cannot communicate with an 802.11b AP and an 802.11b client cannot communicate with an 802.11a AP. However, both 802.11b and 802.11g clients can communicate with an 802.11b/g AP.

Avaya Wireless AP-4/5/6 User’s Guide 1-5 Network Names • All Access Points must have the same Network Name to support client roaming. • All workstations with an 802.11 client adapter installed must use either a Network Name of “any” or the same Network Name as the Access Points that they will roam between. If an AP has Closed System enabled, a client must have the same Network Name as the Access Point to communicate (see Interfaces). Security Settings All Access Points and clients must have the same security settings to communicate. Cell Coverage • The Access Points’ cells must overlap to ensure that there are no gaps in coverage and to ensure that the roaming client will always have a connection available. • The coverage area of an 802.11b or 802.11b/g AP is larger than the coverage area of an 802.11a AP. The 802.11b and 802.11b/g APs operate in the 2.4 GHz frequency band; the 802.11a AP operates in the 5 GHz band. Products that operate in the 2.4 GHz band offer greater range than products that operate in the 5 GHz band.

1-6 Avaya Wireless AP-4/5/6 User’s Guide Data Rates An 802.11a or 802.11b/g AP operates at faster data rates than the 802.11b AP. 802.11a and 802.11g products operate at speeds of up to 54 Mbits/sec; 802.11b products operate at speeds of up to 11 Mbits/sec. Channels • All Access Points in the same vicinity should use a unique, independent Channel. By default, the AP automatically scans for available Channels during boot-up but you can also set the Channel manually (see Interfaces for details). • Access Points that use the same Channel should be installed as far away from each other as possible to reduce potential interference. IEEE 802.11 Specifications In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices operating in the 2.4 GHz frequency band. This standard includes provisions for three radio technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11 standard operate at a data rate of either 1 or 2 Megabits per second (Mbits/sec).

Avaya Wireless AP-4/5/6 User’s Guide 1-7 802.11b In 1999, the IEEE modified the 802.11 standard to support direct sequence devices that can operate at speeds of up to 11 Mbits/sec. The IEEE ratified this standard as 802.11b. 802.11b devices are backwards compatible with 2.4 GHz 802.11 direct sequence devices (that operate at 1 or 2 Mbits/sec). Available Frequency Channels vary by regulatory domain and/or country. See 802.11b Channel Frequencies for details. 802.11a Also in 1999, the IEEE modified the 802.11 standard to support devices operating in the 5 GHz frequency band. This standard is referred to as 802.11a. 802.11a devices are not compatible with 2.4 GHz 802.11 or 802.11b devices. 802.11a radios use a radio technology called Orthogonal Frequency Division Multiplexing (OFDM) to achieve data rates of up to 54 Mbits/sec. Available Frequency Channels vary by regulatory domain and/or country. See 802.11a Channel Frequencies for details. 802.11g In 2003, the IEEE introduced the 802.11g standard. 802.11g devices operate in the 2.4 GHz frequency band using OFDM to achieve data rates of up to 54 Mbits/sec. In addition, 802.11g devices are backwards compatible with 802.11b devices. Available Frequency Channels vary by regulatory domain and/or country. See 802.11g Channel Frequencies for details.

1-8 Avaya Wireless AP-4/5/6 User’s Guide Management and Monitoring Capabilities There are three management and monitoring interfaces available to the network administrator to configure and manage an AP on the network: • HTTP Interface • Command Line Interface • SNMP Management HTTP Interface The HTTP Interface (also known as the Web browser Interface) provides easy access to configuration settings and network statistics from any computer on the network. You can access the Web or HTTP Interface: • over your LAN (switch, hub, etc.), • over the Internet, or • with a “crossover” Ethernet cable connected directly to your computer’s Ethernet Port. Command Line Interface The Command Line Interface (CLI) is a text-based configuration utility that supports a set of keyboard commands and parameters to configure and manage an AP.

Avaya Wireless AP-4/5/6 User’s Guide 1-9 Users enter Command Statements, composed of CLI Commands and their associated parameters. Statements may be issued from the keyboard for real time control, or from scripts that automate configuration. For example, when downloading a file, administrators enter the download CLI Command along with IP Address, file name, and file type parameters. How To Access the CLI You access the CLI over a HyperTerminal serial connection or via Telnet. During initial configuration, you can use the CLI over a serial port connection to configure an Access Point’s IP address. When accessing the CLI via Telnet, you can communicate with the Access Point from over your LAN (switch, hub, etc.), from over the Internet, or with a “crossover” Ethernet cable connected directly to your computer’s Ethernet Port. See Command Line Interface (CLI) for more information on the CLI and for a list of CLI commands and parameters.

1-10 Avaya Wireless AP-4/5/6 User’s Guide SNMP Management You can also manage and configure an AP using the Simple Network Management Protocol (SNMP). NOTE: This requires an SNMP manager program, like HP Openview or Castlerock’s SNMPc. The AP supports several Management Information Base (MIB) files that describe the parameters that can be viewed and/or configured over SNMP: • MIB-II (RFC 1213) • Bridge MIB (RFC 1493) • Ethernet-like MIB (RFC 1643) • 802.11 MIB • Avaya Wireless Enterprise MIB Avaya provides these MIB files on the CD included with each Access Point. You need to compile one or more of the above MIBs into your SNMP program’s database before you can manage an Access Point using SNMP. Refer to the documentation that came with your SNMP manager for instructions on how to compile MIBs.

Avaya Wireless AP-4/5/6 User’s Guide 1-11 The Enterprise MIB defines the read and read-write objects that can be viewed or configured using SNMP. These objects correspond to most of the settings and statistics that are available with the other management interfaces. Refer to the Enterprise MIB for more information; the MIB can be opened with any text editor, such as Microsoft Word, Notepad, or WordPad. NOTE: The remainder of this guide describes how to configure an AP using the HTTP Web interface or the CLI interface. For information on how to manage devices using SNMP, refer to the documentation that came with your SNMP program. Also, refer to the MIB files for information on the parameters available via SNMP.

Getting Started In This Chapter • Prerequisites • Product Package • System Requirements • Hardware Installation • Initialization • Download the Latest Software • Additional Hardware Features Prerequisites Before installing an AP, you need to gather certain network information. The following section identifies the information you need.

Network Name (SSID of the wireless cards) Assign the Access Point a Network Name before wireless users can communicate with it. The clients also need the same Network Name. This is not the same as the System Name, which applies only to the Access Point. The network administrator typically provides the Network Name. AP’s IP Address If you do not have a DHCP server on your network, then you need to assign the Access Point an IP address that is valid on your network. HTTP (Web) Interface Password Each Access Point requires a read/write password to access the Web interface. The default password is “public”. CLI Interface Password Each Access Point requires a read/write password to access the CLI interface. The default password is “public”. SNMP Read Password Each Access Point requires a password to allow get requests from an SNMP manager. The default password is “public”. SNMP Read-Write Password Each Access Point requires a password to allow get and set requests from an SNMP manager. The default password is “public”. Security Settings You need to determine what security features you will enable on the Access Point.

Authentication Method A primary authentication server may be configured; a backup authentication server is optional. The network administrator typically provides this information. Authentication Server Shared Secret This is a password shared between the Access Point and the RADIUS authentication server (so both passwords must be the same), and is typically provided by the network administrator. Authentication Server Authentication Port This is a port number (default is 1812) and is typically provided by the network administrator. Client IP Address Pool Allocation Scheme The Access Point can automatically provide IP addresses to clients as they sign on. The network administrator typically provides the IP Pool range. DNS Server IP Address The network administrator typically provides this IP Address.

Product Package Each Single-radio AP comes with the following: • One metal base for ceiling or desktop mounting (includes two screws) • Mounting hardware — Four 3.5 mm x 40 mm screws — Four 6 mm x 35 mm plugs • One power supply • One Installation CD-ROM that contains the following: — Software Installation Wizard — ScanTool — Solarwinds TFTP software — HTML Help — this user’s guide in PDF format • One Access Point Quick Start Guide If any of these items are missing or damaged, please contact your reseller or Technical Support (see Technical Support for contact information).

MiniPCI Upgrade Kits Single-radio APs can be fitted with different radio types. MiniPCI upgrade kits are available for 802.11a and 802.11b/g wireless cards. Each kit is composed of a single miniPCI board with an integral antenna attached. The type of radio is indicated on the label on the antenna and instructions on how to open your AP to replace the radio are provided with the kit. System Requirements The following are the minimum requirements to begin using an AP: • A 10Base-T Ethernet or 100Base-TX Fast Ethernet switch or hub • At least one of the following IEEE 802.11-compliant devices: • A computer that is connected to the same IP network as the AP and has one of the following Web browsers installed: — Microsoft Internet Explorer 6 with Service Pack 1 or later — Netscape 6.1 or later (The computer is required to configure the AP using the Web or HTTP interface.) You will need an: If you have an: 802.11a client device 802.11a AP 802.11b or 802.11b/g client device 802.11b AP 802.11b/g client device 802.11b/g AP

Initialization Avaya provides two tools to simplify the initialization and configuration of an AP: • ScanTool • Setup Wizard ScanTool is included on the Installation CD; the Setup Wizard launches automatically the first time you access the HTTP interface. NOTE: These initialization instructions describe how to configure an AP over an Ethernet connection using ScanTool and the HTTP interface. If you want to configure the unit over the serial port, see Setting IP Address using Serial Portfor information on how to access the CLI over a serial connection and Command Line Interface (CLI) for a list of supported commands.

ScanTool ScanTool is a software utility that is included on the installation CD-ROM. The tool automatically • detects the Access Points installed on your network, regardless of IP address, • lets you configure each unit’s IP settings, and • allows you to download new software to an AP that does not have a valid software image installed (see Client Connection Problems). To access the HTTP interface and configure the AP, the AP must be assigned an IP address that is valid on its Ethernet network. By default, the AP is configured to obtain an IP address automatically from a network Dynamic Host Configuration Protocol (DHCP) server during boot-up. If your network contains a DHCP server, you can run ScanTool to find out what IP address the AP has been assigned. Default IP Address If your network does not contain a DHCP server, the Access Point’s IP address defaults to 169.254.128.132. In this case, you can use ScanTool to assign the AP a static IP address that is valid on your network. ScanTool Instructions Follow these steps to install ScanTool, initialize the Access Point, and perform initial configuration:

1. Locate the unit’s Ethernet MAC address and write it down for future reference. The MAC address is printed on the product label. Each unit has a unique MAC address, which is assigned at the factory. 2. Confirm that the AP is connected to the same LAN subnet as the computer that you will use to configure the AP. 3. Power up, reboot, or reset the AP. — Result: The unit requests an IP Address from the network DHCP server. 4. Insert the Installation CD into the CD-ROM drive of the computer that you will use to configure the AP. — Result: The installation program will launch automatically. 5. Follow the on-screen instructions to install the Access Point software and documentation. NOTE: The Avaya Wireless Installation program supports the following operating systems: — Windows 98SE — Windows 2000 — Windows Me — Windows XP

6. After the software has been installed, double-click the ScanTool icon on the Windows desktop to launch the program (if the program is not already running). — Result: ScanTool scans the subnet and displays all detected Access Points. The ScanTool’s Scan List screen appears, as shown in the following example. NOTE: If your computer has more than one network adapter installed, you will be prompted to select the adapter that you want ScanTool to use before the Scan List appears. If prompted, select an adapter and click OK. You can change your adapter setting at any time by clicking the Select Adapter button on the Scan List screen. The ScanTool Network Adapter Selection screen will not appear if your computer only has one network adapter installed.

Figure 2-8. Scan List 7. Locate the MAC address of the AP you want to initialize within the Scan List. NOTE: If your Access Point does not show up in the Scan List, click the Rescan button to update the display. If the unit still does not appear in the list, see Troubleshooting for suggestions. Note that after rebooting an Access Point, it may take up to five minutes for the unit to appear in the Scan List.

8. Do one of the following: — If the AP has been assigned an IP address by a DHCP server on the network, write down the IP address and click Cancel to close ScanTool. Go to Setup Wizard for information on how to access the HTTP interface using this IP address. — If the AP has not been assigned an IP address (in other words, the unit is using its default IP address, 169.254.128.132), follow these steps to assign it a static IP address that is valid on your network:

Step Action 1. Highlight the entry for the AP you want to configure. 2. Click the Change button. Result: The Change screen appears. Figure 2-9. Scan Tool Change Screen

3. Set IP Address Type to Static. 4. Enter a static IP Address for the AP in the field provided. You must assign the unit a unique address that is valid on your IP subnet. Contact your network administrator if you need assistance selecting an IP address for the unit. 5. Enter your network’s Subnet Mask in the field provided. 6. Enter your network’s Gateway IP Address in the field provided. 7. Enter the SNMP Read/Write password in the Read/Write Password field (for new units, the default SNMP Read/Write password is “public”). NOTE: The TFTP Server IP Address and Image File Name fields are only available if ScanTool detects that the AP does not have a valid software image installed. See Client Connection Problems. Step Action

8. Click OK to save your changes. Result: The Access Point will reboot automatically and any changes you made will take effect. 9. When prompted, click OK a second time to return to the Scan List screen. 10. Click Cancel to close the ScanTool. 11. Proceed to Setup Wizard for information on how to access the HTTP interface. Step Action

2-52 Avaya Wireless AP-4/5/6 User’s Guide Installing the AP in a Plenum In an office building, plenum is the space between the structural ceiling and the tile ceiling that is provided to help air circulate. Many companies also use the plenum to house communication equipment and cables. However, these products and cables must comply with certain safety requirements, such as Underwriter Labs (UL) Standard 2043: “Standard for Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces”. The AP has been certified under UL Standard 2043 and can be installed in the plenum only when the following conditions apply: • The unit uses Power over Ethernet (PoE) to receive power over a plenum-rated Category 5 Ethernet cable (the power cable must not be connected to the unit). • The unit’s plastic covers have been removed (this includes the cable cover, the front cover, and the back cover). Kensington Security Slot The AP enclosure includes a Kensington Security Slot for use with a Kensington locking mechanism. When properly installed, a Kensington lock can prevent unauthorized personnel from stealing the AP. In addition, the Kensington locks secures the cable cover in place, which prevents tampering with the Ethernet and power cables.

2-54 Avaya Wireless AP-4/5/6 User’s Guide Power over Ethernet An Power over Ethernet-enabled AP is equipped with an 802.3af-compliant Power over Ethernet module. Power over Ethernet (PoE) delivers both data and power to the access point over a single Ethernet cable. If you choose to use Power over Ethernet, there is no difference in operation; the only difference is in the power source. • The Power over Ethernet (PoE) integrated module receives ~48 VDC over a standard Category 5 Ethernet cable. • To use Power over Ethernet, you must have an PoE hub (also known as a power injector) connected to the network. • The cable length between the PoE hub and the Access Point should not exceed 100 meters (approximately 325 feet). • The PoE hub is not a repeater and does not amplify the Ethernet data signal. • If connected to an PoE hub and an AC power simultaneously, the Access Point draws power from Power over Ethernet. • Maximum power supplied to an Access Point is 11 Watts; the unit typically draws approximately 10 Watts. Also see Hardware Specifications. NOTE: The AP’s 802.3af-compliant Power over Ethernet module is backwards compatible with all Avaya Wireless Power over Ethernet hubs that do not support the IEEE 802.3af standard.

Avaya Wireless AP-4/5/6 User’s Guide 2-55 LED Indicators The AP has four LED indicators. The LEDs are identified in LED Indicators Illustrated and exhibit the following behavior: Power Ethernet Link Ethernet Activity Wireless Activity Indication Solid Green Green when link exists Green flash with data activity Green flash with data activity Normal Operation Solid Amber Solid Amber Solid Amber Solid Amber Rebooting/Power on Self Test (POST) Solid Green Solid Amber Solid Amber Solid Amber Reset to Factory Defaults command issued Solid Red Off Off Off SDRAM Test Failure Solid Red Green Off Off If the AP is configured to get an IP address from a DHCP server, it may take up to two minutes to obtain the address. The Power LED will be red and if there is an Ethernet link the Ethernet Link LED will be green during the time the AP is trying to obtain an address. Once an address is obtained, the Power LED will turn green.
