Index of Symptoms, Messages, Error Codes, or
Beeps
Table 2-1 on page 2-11 lists failure symptoms and possible causes. The
most likely cause is listed first. When servicing a system, always begin with
“Start” on page 2-2. This index can also be used to help you decide which
FRUs to have available when servicing a system.
If you are unable to correct the problem using this index, go to
“Undetermined Problem” on page 2-62.
Notes:
1. If an error message and incorrect audio response occur, diagnose the
error message first.
2. If you cannot run the Advanced Diagnostics tests but did receive a
POST error code, diagnose the POST error message.
3. If you did not receive any error message, look for a description of your
error symptoms in the first part of this index.
4. Check all power supply voltages and jumper settings before you replace
the system board. Also check the power supply voltages if you have a
system no-power condition. See “Power Supply” on page 2-26 and
“System Board Layout—Type
I
-1” on page 5-2 and “System Board
Layout—Type
I
-2” on page 5-5.
In Table 2-1 on page 2-11, an X in an error code may be any number. If
you are unable to correct the problem using this index, go to “Undetermined
Problem” on page 2-62.
