SCSI Cables and Guidelines
All workstation models use three areas for connecting mass storage SCSI devices: internally
with hard drive in the removable hard drive cage, internally with storage devices in the front
panel drive bays, and externally with external storage devices. The workstation has an integrated
Wide-Ultra SCSI controller that has one internal connector on the system board and one external
connector on the rear panel.
SCSI Cables
The workstation ships standard with a 5-device Wide-Ultra or Wide Ultra2 SCSI cable that has a
terminator on one end. The other end of this cable connects to the internal Wide-Ultra SCSI
connector on the system board. The first device connector of the cable connects to the hard drive
in the removable hard drive cage. The cable has five connectors to handle up to five SCSI
devices, a maximum of three in the removable hard drive cage and two in the front drive bay
area.
Figure 3-41. 5-device Wide-Ultra SCSI cable
NOTE: The SCSI cable included with the workstation may look slightly different than the one
pictured.
When installing a Wide Ultra2 SCSI hard drive a Wide Ultra2 SCSI cable (not shown) is
required.
Compaq Professional Workstation AP500 Maintenance and Service Guide
3-42
Removal and Replacement Procedures
SCSI Guidelines for Installing SCSI Devices
■
If you are installing a narrow SCSI device, you will need to attach a 68- to 50-pin SCSI
adapter to the narrow SCSI device.
■
A maximum of seven SCSI devices may be installed on the integrated Wide-Ultra SCSI
controller.
■
A unique SCSI ID (0-6 and 8-15) must be set for each SCSI device installed.
■
Before you install a SCSI device, verify the SCSI ID of the drive, and if necessary, set the
SCSI ID to a unique ID number.
■
The controller identifies a SCSI device by its SCSI ID (SCSI ID 1) number rather than its
bay location (Bay 2). Therefore, moving a SCSI device from one bay location to another
or changing the position of the device on the SCSI chain does not affect the
communication between the controller and the SCSI device.
■
The reserved and available SCSI ID numbers for SCSI devices are as follows:
❏
SCSI ID 0 is reserved for the primary hard drive (bootable drive).
❏
SCSI ID 7 is reserved for the controller.
❏
SCSI IDs 1-6 and 8-15 are available. Do not use IDs 8-15 for narrow devices on the
same SCSI bus.
■
Bay 4 is reserved for the CD-ROM drive. Do not install a SCSI device in this bay.
■
If only one SCSI hard drive is used, it should be installed on the lowest numbered bay
(Bay 1).
■
Every SCSI chain must be terminated (closed) at both ends.
■
SCSI devices may not have terminating jumpers on the device. Determine if the device
ought to have termination enabled or disabled. Set the termination if necessary.
Termination on these devices must be achieved with a non-terminated cable.
■
Turn on an external SCSI device before turning on power to the workstation. This enables
the system board controller to recognize the external SCSI device.
■
When an external SCSI device is connected to the external SCSI connector on the rear
panel of the workstation, that device becomes the end of the SCSI chain and must be
terminated.
■
SCSI drives on the SCSI controller must be either internal or in an external storage
system, but not both.
SCSI Guidelines for Optimizing Performance
■
To maintain Ultra speeds, do not install more than four SCSI devices on a SCSI bus.
■
Do not mix Wide-Ultra and narrow SCSI devices on the same SCSI chain or the same
controller.
For additional information about optional SCSI devices, refer to the documentation included
with the device.

External Battery
The real-time clock battery that came with the workstation is permanently installed on the
system board. If the original battery becomes inoperative, you must install a replacement battery.
Before attempting to install the replacement battery, read the following section.
Running Computer Setup
Computer Setup automatically detects and configures most Compaq components, including
Compaq hard drives. If the workstation has a Compaq hard drive you do not need to run
Computer Setup prior to installing the replacement battery. However, if the workstation has a
third-party hard drive, you MUST complete the following steps before installing the replacement
battery:
1.
Run Computer Setup and record the drive type displayed in the System Configuration
Summary.
2.
If the drive type number is 65 or 66, record the drive parameters.
Drives with these designators are user-defined types, also called soft-drive types.
Whenever the nonvolatile memory (CMOS) has be come invalid, such as after the
installation of a new battery, drive parameters must be entered manually for these userdefined drives.
After you have completed the battery installation, run Computer Setup and use the drive table
parameters recorded earlier to reconfigure the system.
WARNING: The system board contains a clock/CMOS lithium battery. The lithium
battery may explode if mistreated. The battery is soldered in and may not be
removed. Do not abuse or disassemble. Use only replacement batteries supplied
by Compaq Computer Corporation.
IMPORTANT: Make a set of backup diagnostics diskettes before installing a new battery.

Audio Hardware Conflicts
This section provides solutions to hardware conflicts. Hardware conflicts occur when two or
more peripheral devices contend for the same signal lines or channels. Conflicts between the
audio interface and another peripheral device may be because of the settings of the base I/O
addresses, interrupts, or DMA channels. The audio interface typically has the following settings:
■
Base I/O address
220H
■
OPL III I/O address
388-38Bh
■
Interrupt
IRQ 5
■
8-bit DMA
Channel 1 and Channel 0 or 3
To resolve hardware conflicts:
1.
Change the hardware settings of the audio card or the peripheral card in your system if the
peripheral card is using the audio interface setting.
2.
If you are unsure of the settings of the peripheral cards, you can isolate the source of the
problem by temporarily removing all cards. After that, add the cards back one at a time
until the card that is causing the conflict is found.

format on the hard drive. Normally, this is only done to add diagnostics to a
replacement hard drive. If the diagnostics software is deleted, you will no longer
be able to access the Compaq Utilities menu.
CAUTION: If you install an operating system without first installing the
diagnostics partition, you will not be able to install a diagnostics partition without
losing all data on your hard disk.
Diagnostic Error Codes
Diagnostic error codes occur if the system recognizes a problem while running the Compaq
Setup and Diagnostics utilities. These error codes help identify defective subassemblies.
The following tables list possible error codes, descriptions of each error condition, and actions
required to resolve the error condition. For assistance in the removal and replacement of a
particular subassembly, see Chapter 3.
NOTE: Retest the system after completing each step. If the problem has been resolved, do not
proceed with the remaining steps.
If you encounter an error condition, complete the following steps before starting problem
isolation procedures:
1.
Ensure proper ventilation. The workstation should have a 6-inch (15 cm) clearance at the
rear of the chassis.
2.
Turn off the workstation and peripheral devices.
CAUTION: Always make sure that the power is off before disconnecting or
reconnecting the mouse, keyboard, or any other peripheral devices. Disconnecting
or connecting any peripheral devices while the unit power is on can damage the
system board.
3.
Disconnect any peripheral devices other than the monitor and keyboard. Do not
disconnect the printer if you want to test it or use it to log error messages.
4.
Install loop-back and terminating plugs for complete testing.
5.
Run the Diagnostics diskette.

SCSI Error Codes
This section includes the error codes for the following SCSI devices:
■
Hard drives
■
CD-ROM drives
■
Tape drives
The SCSI error codes are written in the format AABB-CC and can be determined by looking up
the respective parts of the code in the three corresponding tables numbered 4-26, 4-27, and 4-28.
■
AA (Table 4-26) identifies the drive type being tested.
■
BB (Table 4-27) identifies the type of test.
■
CC (Table 4-28) identifies the exact error received.
For example, if you received a diagnostic error code of 6523-05, you would look at Table 4-26
to identify the meaning of the first two numbers, 65. This indicates a hard drive problem. The
second set of two numbers, 23, refers to a random read, as shown in Table 4-27. The last two
numbers, 05, indicate a seek failure, as listed in Table 4-28. When you combine this information,
you know that the diagnostics program was testing the random-read functioning of the hard drive
and received a seek failure. The device is faulty and must be replaced.

Upgrading the ROM
If the Compaq Professional Workstation AP500 does not have a Setup Password enabled, the
ROM is not write-protected and unauthorized updates can occur. If you need or want to upgrade
the system ROM, you can:
■
Order an upgraded ROMPaq diskette from Compaq.
■
Order the Compaq Support Software CD Kit.
■
Download the latest ROMPaq images from the Compaq website at www.compaq.com.
IMPORTANT: To ensure maximum ROM protection, establish a Setup Password. A Setup
Password prevents unauthorized ROM upgrades.
Local ROM Upgrade
To upgrade the ROM:
1.
Insert the ROMPaq diskette in the diskette drive and turn on the workstation.
CAUTION: To guard against unauthorized updates of the Flash ROM or the
System BIOS, the Setup Password must be set. See Chapter 5 for procedures on
establishing a Setup Password.
2.
If prompted, enter the Setup Password.
NOTE: If the Setup Password is entered correctly, the ROMPaq utility will take over and run the
ROM upgrade. If the Setup Password is incorrectly entered, the procedure will terminate and no
changes will be made to the ROM.
3.
When the utility finishes upgrading the ROM, remove the diskette from the diskette drive
and restart the workstation.
IMPORTANT: Do not turn off the power to the workstation until the ROMPaq utility has
completed the upgrade process.
Compaq Professional Workstation AP500 Maintenance and Service Guide

Remote ROM Flash
Remote ROM Flash allows the system administrator to safely upgrade the ROM on remote
Compaq workstations, directly from the centralized network management console. Enabling the
system administrator to perform this task remotely, on multiple workstations, results in a
consistent deployment of and greater control over workstation ROM images over the network. It
also results in greater productivity and lowers total cost of ownership.
Compaq created the Remote ROM Flash capability to be secure and fail-safe. All workstation
ROMPaq ROM images from Compaq are digitally signed to ensure authenticity and minimize
potential corruption. The ROM firmware includes a Boot Block that is protected during the flash
process and allows the workstation to be restarted, in the unlikely event of an unsuccessful ROM
flash.
Remote ROM Flash is performed in two stages:
1.
The system administrator uses the Remote Management Setup software on a centralized
management console to prepare the workstation ROMPaq file.
2.
The system administrator uses a PC LAN management product, such as Microsoft SMS,
Intel LANDesk Manager, or Symantec Norton Administrator for Networks, to distribute
and execute the file over the network to remote workstations.
NOTE: The workstation must be powered on, or turned on through Remote Wakeup, to take
advantage of Remote ROM Flash. Use of Remote ROM Flash also requires an established Setup
Password.
For more information on enabling Remote ROM Flash, refer to the online Remote Management
Administrators Guide. The Remote Management Administrators Guide is included with the
Remote Management Administration Tools. It is also available in the Support Software CD Kit
or at the Compaq website at www.compaq.com.
4-39
FailSafe Boot Block ROM
The FailSafe Boot Block ROM enables system recovery in the unlikely event of a system ROM
upgrade failure, for example, if a power failure occurs during a system ROM upgrade. The Boot
Block is a flash-protected section of the ROM that checks to validate the system ROM each time
power to the system is turned on.
■
If the system ROM is valid, the system starts normally.
■
If the system ROM fails the validation check, the FailSafe Boot Block ROM provides
enough support to start the system from a ROMPaq diskette, which programs the system
ROM with a valid image.
IMPORTANT: The workstation ships with the Diskette Boot feature enabled. If the diskette
drive is disabled, the FailSafe Boot Block ROM will override the disabled component to
accommodate a system ROM recovery in the event a system ROM failure occurs.
Because there is no video or hard drive support from the Boot Block ROM, the keyboard lights
communicate information. When the Boot Block detects an invalid system ROM, the system
sounds a series of beeps (one long and three short) and flashes the three keyboard lights.
To recover the system after hearing the FailSafe Boot Block beeps:
1.
Remove any diskettes from the diskette drive and turn off the power.
2.
Insert a user ROMPaq diskette into the diskette drive.
3.
Turn on power to the system.
If a Setup Password has been established, the Caps Lock light will turn on.
4.
Enter the Setup Password.
When the system successfully starts from the diskette and reprograms the ROM, the
following three keyboard lights will turn on.
