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 server.
Notes:
1. The field replaceable unit (FRU) procedures in this manual are intended for
trained servicers who are familiar with IBM xSeries products. Customer
replacement units (CRUs) can be replaced by the customer. See the parts
listing in “System” on page 100 to determine if the component being replaced is
a CRU or a FRU.
2. Check the configuration before you replace a FRU. Configuration problems can
cause false errors and symptoms.
3. For IBM devices not supported by this index, refer to the manual for that device.
4. Always start with “General checkout” on page 13.
5. Some tables have more than two columns; in those instances, more than one
column on the left is required to describe the error symptom. Take the action (or
replace the FRU) suggested first in the list of the right-hand column, then try the
server again to see if the problem has been corrected before taking further
action.
6. Always try reseating a suspected component or reconnecting a cable before
replacing the component.
The left-hand column of the tables in this index lists error codes or messages, and
the right-hand column lists one or more suggested actions or FRUs to replace.
The POST BIOS code displays POST error codes and messages on the screen.
