Figure 1 System Unit Front Panel Controls System Power Switch Use the Power switch to power the system unit on and off. Storage Devices Power Switch Power LED System LEDs Removable Volume Mute Headset Mic

7 NOTICE: There is no need to manually shut down the HP- UX operating system on your workstation before powering it off. When you turn off the power switch, your workstation automatically shuts down the operating system before terminating the power. Power LED The Power LED lights when the system unit power is on. System LEDs The Power Light Emitting Diode (LED) is located on the left side of the front panel on the disk tray. It lights when the system unit power is on and flashes until the OS is booted. Once the OS is booted, the LED remains on without flashing, indicating that a soft shutdown is enabled. Each C Class workstation has four diagnostic LEDs located next to the system power LED. LED 4 - System Heartbeat LED 3 - SCSI Bus Activity LED 2 - Network Transmit LED 1 - Network Receive

8 Audio Controls Next to the system LEDs are the following audio con- trols: The volume control, headset jack, and microphone jack features of the CD-ROM are supported through applications only. For more information on the features and electrical specifications, see the section called “Security Loop,” later in this chapter. Storage Device Controls and Features The C Class workstations allow up to two of the fol- lowing internal storage devices: CD-ROM drive, DDS tape drive, or floppy drive. The following sections describe the controls and features of these devices. NOTICES: You may not have two of the same type of device. For example, you can have a CD-ROM device and a floppy device, but not two CD-ROMs. Due to space limitations, a DDS-format tape drive and a CD-ROM drive cannot both be mounted in the system at the same time. Headset Jack Accommodates mini-head- phones with a 3.5 mm diameter miniature stereo plug. Volume Control Adjusts the audio output volume to the headset or lineout. Mic Jack Accommodates microphones with a 3.5 mm diameter minia- ture stereo plug. Mute Button Turns off the audio output to line out and speaker only.

On the C200 systems, ITF is available through the PS/2 connector using a special adaptor and by setting four jumpers on the leg I/O board. HP Parallel I/O Connector The 25-pin HP Parallel I/O interface uses Centronics interface protocols to support peripheral devices such as printers and plotters. Consult the documentation that accompanies each peripheral device for specific information concerning its use. 802.3 Network Connectors The C Class workstations have built-in ThickNet LAN-AUI and LAN-TP (Twisted Pair) connectors for the 802.3 (ETHERNET) network. Connections to ThinLAN networks require an external transceiver. The workstation automatically selects the correct net- work setting.

20 Serial Input/Output Connectors There are a variety of pointing devices (mouse or trackball) or peripheral devices that can attach to the Serial Input/Output (SIO) ports on the workstation. Peripheral devices include printers, plotters, modems, and scanners. Consult the documentation that accom- panies each peripheral device for specific information concerning its use. The SIO ports are programmable, allowing functions such as bit rate, character length, parity, and stop bits to be set. The SIO Ports are used as interfaces for serial asynchronous devices to the CPU. The ports operate at up to a 460.8 K baud rate. Table 5 shows the SIO connector pin listings. The serial connectors are 9-pin D-sub connectors. Signal names are those specified in the EIA RS-232 standard.

21 SCSI Connectors Use the SCSI connectors to connect external SCSI devices such as DDS-format tape drives and CD-ROM drives. Consult the documentation that accompanies each SCSI device for specific information concerning its use. Refer to Appendix C of the C Class Owner’s Guide for information about connecting SCSI devices to your workstation. NOTICE: There must ALWAYS be a terminator at the end of a SCSI bus. This means that an external terminator must be connected to the last device on the external SCSI chain, or on the connector on the rear of the system if no external devices are connected. TOC Button The TOC button resets the system and transfers con- trol from the default device to an auxiliary device. Power Cord Connector Plug the workstation’s power cord into the power cord connector to provide ac power to the system.

a built-in graphics controller. A graphics board is installed in on of the option slots. The Models C160L, C160, and C180 have a graphics controller built-in on the I/O board. The Model C180XP also comes with an extended graphics adapter installed in an option slot. The C Class workstations with built-in graphics sup- ports using one of the following HP monitors: • 17-inch, 1280x1024 color monitor (A4032) • 20-inch, 1280x1024 color monitor (A4033) • 17-inch, 1280x1024 color monitor (A4330) • 20-inch, 1280x1024 color monitor (A4331) The built-in monitor connector is a new Enhanced Video connector. An EVC to DB adapter cable (HP Part No. 8120-6861) is required to use monitors not equipped with an EVC connector.

available: • PS/2 Keyboard (PS/2 interface) (All C Class Workstations) • ITF Keyboard (HP-HIL interface) (C100/110/C160/C180 only) CAUTION: With the HIL interface, use only devices that conform to the HP-HIL specification with Hewlett- Packard computer systems. Devices that are not HP-HIL compatible but have similar connectors may appear to be compatible, but will damage your system. Keyboard Differences Aside from the obvious difference in the appearance of the ITF and PS/2 style keyboards due to the arrangement of the keys, there is also a difference in the keys and their output codes. Some keys on the ITF keyboard may not exist on the other keyboard. These keys generate codes that may not exist as output from the other keyboard (or may be generated by a different key). Codes that are generated when a key is pressed are called keycodes.

by keys existing on the ITF keyboard. Since the keys do not exist on the PS/2 keyboard, an accommodation must be made if the PS/2 keyboard is to be used. In most cases, it is still possible to use some other key that is equivalent (generates the same keycode from a different keycap). To do this, it is necessary to know which keys are equivalent on the two keyboards. Table 6 compares the equivalent keys of the ITF and PS/2 keyboards. NOTICE: Keyboard keys not mentioned in Table 6 are the same on both keyboards.

Figure 11 and Figure 14 show the Narrow Single-Ended SCSI ID settings for the CD- ROM drive and the DDS drive. Figure 16 shows the Operation Mode switches for the DDS drive. NOTE: There are no jumper settings to change for the floppy drive. These SCSI IDs are the default IDs for each storage device. If an existing device already uses an ID, select an alternate ID. Table 8 Storage Configurations Disk Tray Position Supported Devices Conditions 1 Floppy Drive 1-inch Low Profile Disk Drive 2 CD-ROM DDS-Tape 3 1-inch Low Profile Disk Drive 1.6-inch Full Height Disk Drive If a CD-ROM drive is installed, install a 1.6-inch full height disk drive in this position. 4 1-inch Low Profile Disk Drive 1.6-inch Full Height Disk Drive This is the preferred position for a 1.6-inch full height disk drive. If a CD-ROM drive is installed, a 1.6-inch full height disk drive can- not be installed in this position. Hard disk drives are FWD SCSI devices on C100/110/160/180. Hard dis- kdrives are UWSE SCSI devices on C200/240/360. The CD-ROM drive and the DDS tape drive are single-ended SCSI devices. The floppy drive is not a SCSI device.

Operation Mode

The Model C100/110/160L workstations have 8 mem- ory slots, labeled 0A, 0B through 3A, 3B. The mem- ory configuration is 32 MB to 512 MB installed in pairs of 16 MB, 32 MB, or 64 MB memory modules. The Model C160/180XP/200/240/360 workstations have 12 memory slots, labeled 0A, 0B through 5A, 5B. The memory configuration is 32 MB to 1.5 GB installed in pairs of 16 MB, 32 MB, 64 MB or 128 MB memory modules. Memory modules must be installed in pairs of equal capacity. Always install the largest capacity memory modules in the lowest numbered memory slots and don’t skip any numbers. For example, if you have a pair of 16 MB memory modules and a pair of 64 MB memory modules, first install the pair of 64 MB memory modules in slots 0A and 0B, then install the 16 MB modules in slots 1A and 1B. Figure 17 shows the positions of the memory connec- tors on the Models C100/110 CPU board. Figure 18 shows the positions of the memory connec- tors on the Model C160L CPU board. Figure 19 shows the positions of the memory connec- tors on the Models C160/180XP/200/240/360 CPU board.

port the following two monitors: • 17-inch, 1280x1024 color monitor (A4032A) • 20-inch, 1280x1024 color monitor (A4033A) The monitor type does not have to be changed on the workstation since the workstation is set up to support these monitors. However, if for some reason the moni- tor type needs to change, refer to Chapter 9 of this book. NOTICE: Unsupported monitors may “lock up” if they cannot sync to a scan rate. Changing the Console to External Terminal In the event that your console stops displaying to your graphics device, use the following procedure to display to console to an external terminal: 1 Turn system power off. 2 Disconnect the PC keyboard connector from the system rear panel. 3 Connect a serial terminal to the Serial 1 connector (the top serial connector) on the system rear panel. 4 Power on the system. The system will now display the console to the terminal connected to the Serial 1 port. Note that you can use a 9-pin to 9-pin serial cable (HP F1044-80002) to connect an HP OmniBook serial port to the workstation.

graphics0 through graphics2 are not supported. If the configuration value is set to “default” (graphics 0), the system console will be graphics 3, Slot 3. graphics3 Graphics device in slot3. If there is a Dual Graphics Card in slot4, this is the port to the right on the card when facing the back of the workstation. graphics4 Graphics device in slot4. If there is a Dual Graphics Card in slot3 or 4, this is the port to the left on the card when facing the back of the workstation. NOTICE: If you install a VISUALIZE-48 graphics card (geometry accelerator board installed in slot 3 or slot 4) the system path is graphics 3. If your workstation is running HPUX 9.05, the system console graphics device must be installed in Slot 3. If your workstation is running HPUX 9.07 or later, the system will find a console graphics device installed in Slot 3 by default. You may install the console graphics device in Slot 4 if you modify your system files as described in HP Visual User Environment User’s Guide or HPUX X User Environment User’s Guide.

This subsection describes the graphics configuration rules and restrictions for the Models C160 and C180. Note that a C200 upgraded from a C160/C180 will have these same rules and restrictions. Graphics Paths graphics(0) is the built-in 8-plane graphics adapter. graphics(1) through graphics(4) are graphics adapters installed in option slots 1 through 4. When a dual display graphics adapter (an adapter which has two video output connectors) is installed, the video connector on the left (when looking at the system from the rear) is graphics(NA) and the video connector on the right is graphics(NB). Where N is the slot number in which the graphics adapter is installed. A and B denote the two video output connectors on the dual display adapter. For example, a Dual Visualize Enhanced Graphics Card (A4451A) installed in option slot 3 would be graphics(3A) and graphics(3B).

This subsection describes restrictions on the installa- tion and support of graphics adapters. Graphics Displays The system supports only four graphics displays at a time. A “display” is a video out- put port or connector. For example, the Dual Visualize Enhanced Graphics Card (A4451A) is a dual display card. It has two external video connectors so it accounts for two of the maximum of four displays. If you install two of these cards they account for four displays, which is the maximum supported by the sys- tem. The built-in graphics adapter accounts for one graph- ics display (graphics(0)). If four displays are installed in the option slots, the built-in graphics adapter is automati- cally disabled. Dual Graphics Adapters You may not install a dual display graphics adapter in option slot 1 and option slot 3 at the same time. Installing a dual display graph- ics adapter in option slot 1 and option slot 3 at the same time results in the graphics adapter in slot 1 being disabled. You may not install a dual display graphics adapter in option slot 2 and option slot 4 at the same time. Install- ing a dual display graphics adapter in option slot 2 and option slot 4 at the same time results in the graphics adapter in slot 2 being disabled. Multi-board Graphics Adapters When a Visualize48Z (A4244A) two board graphics adapter is installed, Only one other graphics adapter may be installed in the option slots. If the highest numbered slot used by the Visualize 48Z board set is an even numbered slot, then you may only install a graphics card in the

slot used by the Visualize 48Z board set is an odd numbered slot, then you may only install a graphics card in the remaining even numbered slot. For exam- ple; assuming a Visualize 48Z board set is installed in slots 1 and 2, slot two is the highest numbered slot used and it is an even numbered slot. Therefore you may only install an additional graphics adapter in slot 3 which is the remaining odd numbered slot. NOTICE: The A4077A Color Graphics Card, A4078A Dual Color Graphics Card, A4079B HCRX-8Z graphics adapter, and the A4071B HCRX-24 graphics adapter with the A4072A Z Accelerator attached are not supported in the Model C160/C180.

rules and restrictions for the Models C160L. Graphics Paths graphics(0) is the built-in 8-plane graphics adapter. graphics(1) and graphics(2) are graphics adapters installed in option slots 1 and 2. When a dual display graphics adapter (an adapter which has two video output connectors) is installed, the video connector on the left (when looking at the system from the rear) is graphics(NA) and the video connector on the right is graphics(NB). Where N is the slot number in which the graphics adapter is installed. For example, a Dual Visualize Enhanced Graphics Card (A4451A) installed in option slot 2 would be graphics(2A) and graphics(2B).

The system supports only four graphics displays at a time. A “display” is a video output port or connector. For example, the Dual Visualize Enhanced Graphics Card (A4451A) is a dual display card. It has two exter- nal video connectors so it accounts for two of the max- imum of four displays. If you installed two of these cards they would account for the maximum of four displays supported by the system. The built-in graphics adapter accounts for one graph- ics display (graphics(0)). If four displays are installed in the option slots, the built-in graphics adapter is automatically disabled. NOTICE: The A4077A Color Graphics Card and A4078A Dual Color Graphics Card are not supported in the Model C160L. The Model C160l only supports the A4211A HP Visualize48 graphics adapter. It does not support the A4244A HP Visualize48 graphics adapter. Optional graphics adapters may only be installed in option slots 1 and 2 since only these 2 slots support GSC boards. NOTE: The Model C200 and C240 systems do not have a built-in graphics card, but use an optional graphics card.

failing component, known as a Field Replaceable Unit (FRU), in the C Class workstations.

63 Getting Ready to Troubleshoot To troubleshoot a C Class workstation, you must be familiar with the HP-UX operating system and be able to start and stop processes. You should also be familiar with the boot ROM diagnostics, ISL diagnostics, and the SupportWave and Support Tools Manager online tests, which we describe in this chapter. Note any error or status messages, then run the power- up boot ROM diagnostics, known as Self Test. If the Self Test diagnostics fail, replace the FRU that is indi- cated. If the tests pass but you still suspect a problem, run the ISL diagnostics and the SupportWave and Sup- port Tools Manager online tests. For a complete description of using ISL diagnostics and SupportWave, see the Precision Architecture RISC HP Apollo 9000 Series 700 Diagnostics manual. In the following flowcharts, use Figure 20 (flowchart 1) and Figure 21 (flowchart 2) to trouble- shoot based on whether or not the LEDs light. Use Figure 22 (flowchart 3) and Figure 23 to troubleshoot the HP-UX environment.

68 Dealing with a Boot Failure To start the workstation from an operating system stored on a device different from the usual boot device, to boot from a different disk, or to boot from another type of device (such as a DDS tape drive), see the following situations and examples that use the Boot Console Interface. To access the Boot Console Interface, see Chapters 9 and 10 of this book. • To boot from a known device containing a bootable operating system, type the following at the prompt: boot where device is the hardware path to the device, speci- fied in Mnemonic Style Notation as listed in the follow- ing table: For example, to boot an operating system stored on a DDS-format tape in a drive located at Single-ended SCSI ID 1 type the following command at the prompt: Table 10 Bootable Device Types C100/110 C160l/160/180/ 200/240/360 Description fwscsi fwscsi built-in FWD or UWSE SCSI bus slotn.fwscsi gscn optional FWD SCSI bus scsi sescsi built-in narrow SE SCSI bus lan lan all connections to the built-in LAN

69 boot sescsi.1.0 (C160L, C160, and C180) boot scsi.1.0 (C100 and C110) The operating system on the specified device is used to start the workstation. • To interact with the Initial System Loader (ISL) before booting the workstation, type the following at the prompt: boot You are prompted: Interact with ISL (Y, N, Q) > Answering yes (y) causes the ISL to be loaded from the specified device. After a short time, the following prompt appears on the screen: ISL> ISL is the program that actually controls the loading of the operating system. By interacting with ISL, you can choose to load an alternate version of the HP-UX oper- ating system. For example, if the usual kernel (/hp-ux for 9.05 and /stand/vmunix for 10.0) on the root disk (fwscsi.6.0) has become corrupted, boot the workstation from the backup kernel (/SYSBCKUP for 9.05, and /stand/vmunix.prev for 10.0) by typing the following at the ISL> prompt: hpux /SYSBCKUP (for 9.05) hpux /stand/vmunix.prev (for 10.0) • To find the location of the bootable operating systems on the various media in the file system, use the search com- mand.

70 Searching for Bootable Media To list all devices that may contain bootable media, go to the Main Menu of the Boot Console Interface and then type the following at the prompt: search ipl The search may turn up more devices than there are lines on the display. If using a text terminal, control the progress of the search from the terminal’s key- board by performing the following steps: • To hold the display temporarily, press Ctrl S • To continue the display, press Ctrl Q • To halt the search, press Esc These flow-control commands do not work with a bitmapped display, but such a display can show more than forty lines of text, so they are unnecessary. To search for devices of just one type that actually con- tain bootable media, go to the Main Menu of the Boot Console Interface and then type the following at the prompt: search ipl device_type where device_type is one of the values listed in the fol- lowing table: Table 11 Bootable Device Types C100/110 C160l/160/180/ 200/240/360 Description fwscsi fwscsi built-in FWD or UWSE SCSI bus slotn.fwscsi gscn optional FWD SCSI bus scsi sescsi built-in narrow SE SCSI bus

71 Stable Storage Stable Storage is non-volatile memory associated with each PA-RISC processor module. Stable storage is used by the processor (CPU) to store device path information, the state of the boot flags, HPMC error information, and operating system initialization data. Boot Command Notations The boot command supports the following two notations: • Mnemonic • Path number Type help scsi or help lan for more information on the boot path parameters. Here are examples of mnemonic notation: • boot with “no parameters” selects the primary boot path in stable storage. • boot with the alternate or alt parameter selects the alter- nate boot path in stable storage. Here is an example of path number notation: boot p1 attempts to boot from the second path indicated by the search command. lan lan all connections to the built-in LAN Table 11 Bootable Device Types C100/110 C160l/160/180/ 200/240/360 Description

72 Supported Boot Paths SCSI devices are bootable when connected to the NSE SCSI and FWD or UWSE SCSI ports on the System card. Diskless workstations can only boot from the LAN port on the System card. ISL Environment The ISL environment provides the means to load the operating system (HP-UX) environment. The ISL environment also provides an offline platform to exe- cute diagnostic and utility programs from a boot device when HP-UX does not load. The ISL program is the first program loaded into main memory from an external media (LAN, disk, or tape) and launched by the initial program loader (IPL) rou- tine during the Boot Administration environment. The ISL environment provides the following capabili- ties: • Execute user-entered commands to modify boot device paths and boot options in stable storage. • Run offline diagnostic programs (TDIAG, IOMAP). • Provide automatic booting of the HP-UX O/S after power-on or reset. The ISL program provides a standalone environment for loading offline diagnostic and utility programs from the LIF directory. The ISL program also provides user commands to configure the boot parameters into Stable Storage.
