To perform the checkout procedure, complete the following steps:
1. Is the server part of a cluster?
2. Complete the following steps:
3. Did more than one beep sound?
v No: Go to step 2.
v Yes: Shut down all failing servers that are related to the cluster. Go to step 2.
a. Check the power supply LEDs, see "Power-supply LEDs" on page 53.
b. Turn off the server and all external devices.
c. Check all internal and external devices for compatibility at
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
d. Make sure the server is cabled correctly.
e. Check all cables and power cords.
f. Set all display controls to the middle positions.
g. Turn on all external devices.
h. Turn on the server. If the server does not start, see "Troubleshooting tables"
on page 36.
i. Check the system-error LED on the operator information panel. If it is
flashing, check the LEDs on the system board (see "System-board LEDs" on
page 15).
j. Check for the following results:
v Successful completion of POST (see "POST" on page 17 for more
information)
v Successful completion of startup
Note: A single beep indicates successful completion of POST and is not an
error.
v No: (No beeps sounded) Find the failure symptom in "Troubleshooting tables"
on page 36; if necessary, run the diagnostic programs (see "Running the
diagnostic programs" on page 55).
– If you receive an error, see "Diagnostic error codes" on page 56.
– If the diagnostic programs were completed successfully and you still
suspect a problem, see "Solving undetermined problems" on page 76.
