The Symptom-to-FRU index lists error symptoms and possible causes. The most
likely cause is listed first. Always begin with Chapter 1, "General checkout", on
page 1. This index can also be used to help you decide which FRUs to have
available when servicing a computer. If you are unable to correct the problem
using this index, go to "Undetermined problems" on page 71.
In the following indexes, X can represent any number.

Notes:
v If you have both an error message and an incorrect audio response, diagnose the error
message first.
v If you cannot run the diagnostic tests or you get a diagnostic error code when running a
test, but did receive a POST error message, diagnose the POST error message first.
v If you did not receive any error message, look for a description of your error symptoms
in the first part of this index.
v Check all power supply voltages before you replace the system board (see "Power
supply" on page 44).
v Check the hard disk drive jumper settings before you replace a hard disk drive (see
"Hard disk drive jumper settings" on page 32).
Important:
Some errors are indicated with a series of beep codes (see "Beep symptoms" on page 48).
Type 6838, 6848 computers default to come up quiet (no beep and no memory count and
checkpoint code display) when no errors are detected by POST. To enable beep and
memory count and checkpoint code display when a successful POST occurs, do the
following:
1. Select Start Options in the Configuration/Setup Utility program (see "Using the
Configuration/Setup Utility program" on page 19).
2. Set Power-On Self-Test to Enhanced.
The processor is a separate FRU from the system board; the processor is not included with
the system board FRU.
