Chapter 1. General checkout
The server diagnostic programs are stored on CD-ROM. These programs are the
primary method of testing the major components of the server: 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 12.
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 75.
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 69.

Chapter 3. Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with the server.
If you cannot locate and correct the problem using the information in this section,
refer to Chapter 7, “Symptom-to-FRU index”on page 63 for more information.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
vPOST beep codes
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “POST”for more
information.
vDiagnostic programs and error messages
The server diagnostic programs are provided on the IBM Enhanced Diagnostics
CD. These programs test the major components of the server. See “Diagnostic
programs and error messages”on page 12 for more information.
POST
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of
tests is called the power-on self-test or POST.
If POST finishes without detecting any problems, the first window of the operating
system or application program appears.
Note:
1. If you have a power-on password or administrator 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 beep code descriptions
POST generates beep codes to indicate successful completion or the detection of a
problem.
vOne short beep indicates the successful completion of POST.
vMore than one beep indicates that POST detected a problem. For more
information, see “Beep symptoms”on page 63“.
POST error messages
The possible types of beep codes that your system might emit are:
© Copyright IBM Corp. 2000 11

Repeating long beeps
Indicates that a memory error has occurred. Ensure that all DIMMs are
correctly installed.
One long beep and two short beeps
Indicates that a video error has occurred and the BIOS cannot initialize the
video screen to display any additional information. Ensure that the video
adapter is correctly installed.
For a list of POST errors, see “POST error codes”on page 69.
Small computer system interface messages (some models)
The following table lists actions to take if you receive a SCSI error message.
Note: If the server does not have a hard disk drive, ignore any message that
indicates that the BIOS is not installed.
You will get these messages only when running the SCSI Select Utility.
Table 1. SCSI messages
SCSI Messages Description
All One or more of the following might be causing the problem.
vA failing SCSI device (adapter or drive)
vAn improper SCSI configuration
vDuplicate SCSI IDs in the same SCSI chain
vAn improperly installed SCSI terminator
vA defective SCSI terminator
vAn improperly installed cable
vA defective cable
Action: Verify that:
vThe external SCSI devices are turned on. External SCSI devices must
be turned on before the server.
vThe cables for all external SCSI devices are connected correctly.
vThe last device in each SCSI chain is terminated properly.
vThe SCSI devices are configured correctly.
If the above items are correct, run the diagnostic programs to obtain
additional information about the failing device.
Diagnostic programs and error messages
The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
These programs provide the primary methods of testing the major components of
the server.
Diagnostic error messages indicate that a problem exists; they are not intended to
be used to identify a failing part. Troubleshooting and servicing of complex
problems that are indicated by error messages should be performed by trained
service personnel.
