Chapter 6. Symptom-to-FRU index
This index supports xSeries 345 servers.
Notes:
1. Check the configuration before you replace a FRU. Configuration problems can
cause false errors and symptoms.
2. For IBM devices not supported by this index, refer to the manual for that device.
3. Always start with “General checkout” on page 25.
The symptom-to-FRU index lists symptoms, errors, and the possible causes. The
most likely cause is listed first. Use this symptom-to-FRU index to help you decide
which FRUs to have available when servicing the computer.
The first column of the two-column tables in this index lists error codes or
messages, and the second column lists one or more suggested actions or FRUs to
replace. Take the action (or replace the FRU) suggested first in the list of the
second column, then try the server again to see if the problem has been corrected.
Note: Try reseating a suspected component or reconnecting a cable before
replacing the component.
The POST BIOS code displays POST error codes and messages on the screen.

(intervals without sound). See the examples in the following table.
