disk drive in the storage unit) or the storage adapter that is attached to the
storage unit. The failing computer might be part of a cluster if any of the following
conditions is true:
– You have identified the failing computer as part of a cluster two or more
computers sharing external storage devices).
– 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.
Important: If the computer is part of a shared hard disk drive cluster, run one
test at a time. Do not run any suite of tests, such as “quick” or “normal” tests,
because this might enable the hard disk drive diagnostic tests.

If the computer is halted and a POST error code is displayed, see “POST error
codes” on page 18. If the computer is halted and no error message is displayed,
see “Troubleshooting tables” on page 30 and “Solving undetermined problems”
on page 65.

codes, and messages” on page 40.
Performing the checkout procedure
To perform the checkout procedure, complete the following steps:
1. Is the computer part of a cluster?
v No: Go to step 2.
v
Yes: Shut down all failing computers that are related to the cluster. Go to
step 2.
2. Complete the following steps:
a. Turn off the computer and all external devices.
b. Check all cables and power cords.
c. Set all display controls to the middle positions.
d. Turn on all external devices.
e. Turn on the computer. If the computer does not start, see the

f. Check the system board and microprocessor board for LEDs (see “System
board LED errors” on page 50 and “Microprocessor board LED errors” on
page 53 ).
g. Check the following results:
v
Successful completion of POST, indicated by a single beep
v
Successful completion of startup, indicated by a readable display of the
operating-system desktop
3. Did a single beep sound and are there readable instructions on the main menu?
v
No: Find the failure symptom in “Troubleshooting tables” on page 30; if
necessary, see “Solving undetermined problems” on page 65.
v Yes: Run the diagnostic programs (see “Starting the diagnostic programs and
viewing the test log” on page 40).
– If you receive an error, see “Diagnostic error codes” on page 42.
– If the diagnostic programs were completed successfully and you still
suspect a problem, see “Solving undetermined problems” on page 65.
