General checkout
The server/workstation diagnostic programs are stored in upgradable read-only
memory (ROM) on the system board. These programs are the primary method of
testing the major components of the server/workstation: the system board,
Ethernet controller, video controller, RAM, keyboard, mouse (pointing device),
diskette drive, serial ports, and hard drives. You can also use them to test some
external devices. See “Diagnostic programs and error messages”on page 15.
Also, if you cannot determine whether a problem is caused by the hardware or by
the software, you can run the diagnostic programs to confirm that the hardware is
working properly.
When you run the diagnostic programs, a single problem might cause several error
messages. When this occurs, work to correct the cause of the first error message.
After the cause of the first error message is corrected, the other error messages
might not occur the next time you run the test.
A failed system might be part of a shared DASD cluster (two or more systems
sharing the same external storage device(s)). Prior to running diagnostics, verify
that the failing system is not part of a shared DASD cluster.
A system might be part of a cluster if:
vThe customer identifies the system as part of a cluster.
vOne or more external storage units are attached to the system and at least one of
the attached storage units is additionally attached to another system or
unidentifiable source.
vOne or more systems are located near the failing system.
If the failing system is suspected to be part of a shared DASD cluster, all
diagnostic tests can be run except diagnostic tests which test the storage unit
(DASD residing in the storage unit) or the storage adapter attached to the storage
unit.
Notes:
1. Safety information, see “Safety information”on page 147.
2. For systems that are part of a shared DASD cluster, run one test at a time in
looped mode. Do not run all tests in looped mode, as this could enable the
DASD diagnostic tests.
3. If multiple error codes are displayed, diagnose the first error code displayed.
4. If the computer hangs with a POST error, go to “POST error codes”on
page 127.
5. For intermittent problems, check the error log; see “Event/error logs”on
page 12.

Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with the server/workstation.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
vPOST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “POST”on page 12
for more information.
vDiagnostic programs and error messages
The server/workstation diagnostic programs are stored in upgradable read-only
memory (ROM) on the system board. These programs are the primary method
of testing the major components of your server/workstation. See “Diagnostic
programs and error messages”on page 15 for more information.
vLight Path Diagnostic
The Light Path Diagnostic is used to quickly identify system errors.

POST
When you turn on the server/workstation, it performs a series of tests to check the
operation of server/workstation components and some of the options installed in
the server/workstation. This series of tests is called the power-on self-test or POST.
If POST finishes without detecting any problems, a single beep sounds and the
first screen of your operating system or application program appears.
If POST detects a problem, more than one beep sounds and an error message
appears on your screen. See “POST error messages”for more information.
Notes
™
:
1. If you have a power-on password set, you must type the password and press
Enter, when prompted, before POST will continue.
2. A single problem might cause several error messages. When this occurs, work
to correct the cause of the first error message. After you correct the cause of the
first error message, the other error messages usually will not occur the next
time you run the test.
POST error messages
The table “POST error codes”on page 127 provides information about the POST
error messages that can appear during startup.
Event/error logs
The POST error log contains the three most recent error codes and messages that
the system generated during POST. The System Event/Error log contains all
messages issued during POST and all system status messages from the Advanced
System Management Processor.
To view the contents of this error log, start the Configuration/Setup Utility
program; then, select Event/Error Logs from the main menu.
Small computer system interface messages
The following table lists actions to take if you receive a SCSI error message.
Note: If the server/workstation does not have a hard disk drive, ignore any
message that indicates that the drive is not installed.
You will get these messages only when running the SCSISelect Utility. See “SCSI
error codes”on page 131.
