Chapter 3. Diagnostics
This section provides basic troubleshooting information to help you solve some
problems that might occur.
General checkout
Follow the checkout procedure for diagnosing hardware problems. Review the
following information before performing the checkout procedure:
vRead Appendix B, “Safety information,” on page 115.
vThe system diagnostic programs are stored on ahidden partition on the
computer hard disk. These programs are the primary method of testing the major
components of the computer: the system board, Ethernet controller, video
controller, RAM, keyboard, mouse (pointing device), serial ports, hard disk drives,
and parallel port. You can also use them to test some external devices. If you are
not sure whether aproblem is caused by the hardware or by the software, you
can use the diagnostic programs to confirm that the hardware is working
correctly.
vWhen you run the diagnostic programs, asingle problem might cause several
error messages. If you receive several error messages, correct the cause of the
first error message. The other error messages might not occur the next time you
run the diagnostic programs.
vBefore running the diagnostic programs, you must determine whether the failing
computer is part of ashared hard disk drive cluster (two or more computers
sharing external storage devices). If you suspect that it is part of acluster, you
can run all diagnostic programs except the ones that test the storage unit (that is,
ahard disk drive in the storage unit) or the storage adapter that is attached to
the storage unit. The failing computer might be part of acluster if any of the
following conditions is true:
–The customer identifies the failing computer as part of acluster.
–One or more external storage units are attached to the failing computer and at
least one of the attached storage units is also attached to another computer
or unidentifiable device.
–One or more computers are located near the failing computer.
vImportant:
1. For computers that are part of ashared hard disk drive cluster, run one test
at atime. Do not run any suite of tests, such as “quick” or “normal” tests,
because this could enable the hard disk drive diagnostic tests.
2. If more than one error code is displayed, correct the first error. The other
error codes might not occur the next time you run the diagnostic programs.
3. If the computer is suspended and aPOST error code is displayed, see
“POST error codes” on page 95.
4. If the computer is suspended and no error message is displayed, see “Error
symptoms” on page 87 and “Undetermined problems” on page 102.
5. For information about power-supply problems, see “Power checkout” on page
25.
6. For intermittent problems, check the error log; see “Diagnostic programs and
error messages” on page 12.
©Copyright IBM Corp. 2004 9

Complete the following steps to perform the checkout procedure:
001 IS THE COMPUTER PART OF ACLUSTER?
YES. Schedule maintenance for the computer. Shut down all computers
related to the cluster. Run the storage test.
NO. Go to step 002.
002 IF THE COMPUTER IS NOT PART OF ACLUSTER:
1. Check the system board LEDs (see “System board error LEDs” on page
79).
2. Turn off the computer and all external devices.
3. Check all cables and power cords.
4. Set all display controls to the middle position.
5. Turn on all external devices.
6. Turn on the computer.
7. Watch the screen for POST errors, and record any POST error
messages that are displayed on the screen. If an error is displayed, look
up the first error (see “POST error codes” on page 95).
8. Run the diagnostic programs (see “Starting the diagnostic programs and
viewing the test log” on page 13).
003 DID THE DIAGNOSTIC PROGRAMS START ?
NO. Find the failure symptom in “Error symptoms” on page 87.
YES. Run the diagnostic programs (see “Starting the diagnostic programs
and viewing the test log” on page 13).
If you receive an error, see Chapter 6, “Symptom-to-FRU index,” on page
83.
If the diagnostics were completed successfully and you still suspect a
problem, see “Undetermined problems” on page 102.
If the computer does not turn on, see “Error symptoms” on page 87.
Diagnostic tools overview
The following tools are available to help you diagnose and solve hardware-related
problems:
vPOST beep codes and error messages
The power-on self-test generates beep codes and messages to indicate
successful test completion or the detection of aproblem. See “POST error log”
on page 11 for more information.
vDiagnostic programs
The system diagnostic programs are on ahidden partition on the hard disk.
These programs are the primary methods of testing the major components of the
computer. See “Diagnostic programs and error messages” on page 12 for more
information.
vError charts
These charts list problem symptoms and steps to correct the problem. See “Error
symptoms” on page 15 for more information.
