Performing The Checkout Procedure; Checkpoint Codes (Trained Service Technicians Only) - IBM xSeries 100 Problem Determination And Service Manual

Performing the checkout procedure

To perform the checkout procedure, complete the following steps:
1. Is the server part of a cluster?
2. Complete the following steps:
3. Did one or more beeps sound, or was a POST error code displayed?

Checkpoint codes (trained service technicians only)

A checkpoint code identifies the check that was occurring when the server stopped;
it does not provide error codes or suggest replacement components. Checkpoint
codes are shown on the checkpoint display, which is on the system board. By using
the checkpoint display, you do not have to wait for the video to initialize each time
you restart the server.
There are two types of checkpoint codes: complex programmable logic device
(CPLD) hardware checkpoint codes and BIOS checkpoint codes. The BIOS
checkpoint codes might change when the BIOS code is updated.
For a list of checkpoint codes for the xSeries 100 server, see
http://w3.pc.ibm.com/helpcenter/infotips/techinfo/MIGR-58350.html.
v No: Go to step 2.
v Yes: Shut down all failing servers that are related to the cluster. Go to step 2.
a. Turn off the server 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 server. If the server does not start, see "Troubleshooting tables"
on page 25.
f. Check the system-error LED on the front of the server. If it is lit, check the
LEDs on the system board (see "System-board LEDs" on page 10).
g. Check for the following results:
v Successful completion of POST, indicated by no beep sounds
v Successful completion of startup, indicated by a readable display of the
operating-system desktop
v Yes: Find the beep code or error code in "POST beep codes" on page 13 or
"POST error codes" on page 16; if necessary, see "Solving undetermined
problems" on page 47.
v No: Find the failure symptom in "Troubleshooting tables" on page 25; if
necessary, run the diagnostic programs (see "Running the diagnostic
programs" on page 37).
– If you receive an error, see "Diagnostic error codes" on page 39.
– If the diagnostic programs were completed successfully and you still
suspect a problem, see "Solving undetermined problems" on page 47.
