IBM 8649 - Eserver xSeries 225, Maintenance And Troubleshooting Manual, Page: 111 / 194

Chapter 6. Symptom-to-FRU index
This index supports xSeries 225 servers.
Notes:
1. Check the configuration before you replace a CRU or 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 19
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.
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.
Beep symptoms
Beep symptoms are short tones or a series of short tones separated by pauses
(intervals without sound). See the examples in the following table.
