Performing the checkout procedure
To perform the checkout procedure, complete the following steps:
1. Is the server part of a cluster?
v No: Go to step 2.
v Yes: Shut down all failing servers that are related to the cluster. Go to step 2.
2. Complete the following steps:
a. Make sure that both the ac and dc power supply LEDs on the rear of the
power supply are lit, indicating that the power supply is operating correctly
(see “Power supply LEDs” on page 161).
b. Turn off the server and all external devices.
c. Check all internal and external devices for compatibility at:
d. Check all cables and power cords.
e. Set all display controls to the middle positions.
f. Turn on all external devices.
g. Turn on the server. If the server does not start, see “Troubleshooting tables”
on page 147.
h. Check the system-error LED on the front panel. If it is lit, check the LEDs on
the system board (see “Error LEDs” on page 160).
Important: If the system-error LED on the front of the server is lit but there
are no other error indications, clear the BMC system-event log. This log
does not clear itself, and if it begins to fill up, the system-error LED will be
lit. Also, after you complete a repair or correct an error, clear the BMC
system-event log to turn off the system-error LED on the front of the server.
i. Check for the following results:
v Successful completion of POST, indicated by one beep
v Successful completion of startup
3. Did more than one beep sound, or was a POST error code displayed?
v Yes: Find the beep code or error code in “POST beep codes” on page 130 or
“POST error codes” on page 135; if necessary, see “Solving undetermined
problems” on page 245.
v No: Find the failure symptom in “Troubleshooting tables” on page 147; if
necessary, run the diagnostic programs (see “Running the diagnostic
programs” on page 164).
– If you receive an error, see “Diagnostic messages” on page 165.
– If the diagnostic programs were completed successfully and you still
suspect a problem, see “Solving undetermined problems” on page 245.
