IBM IntelliStation E Pro, Hardware Maintenance Manual

Symptom-to-FRU index
This index supports the IntelliStation E Pro computer.
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, see the manual for that device.
3. Always start with “General checkout” on page 1.
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 initial column or columns of the tables in this index lists error codes or
messages, and the final 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
entries in the final column, and then restart the computer 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.
