Chapter 6. Symptom-to-FRU Index

SDRAM memory errors	.	.	.	. 70		No-beep symptoms	.	.	92
Hard disk drive boot error	.	.	.	.	70	POST error codes	.	.	93
Power Supply Errors	.	.	.	.	71	Miscellaneous error messages	.		107
Diagnostic error codes	.	.	.	.	72	Undetermined problems	.		109
Beep symptoms	.	.	.	.	90

The Symptom-to-FRU index lists error symptoms and possible causes. The most likely cause is listed first. Always begin with ″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 109.

Notes:

vIf you have both an error message and an incorrect audio response, diagnose the error message first.

vIf 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.

vIf you did not receive any error message, look for a description of your error symptoms in the first part of this index.

vCheck the hard disk drive jumper settings before you replace a hard disk drive.

Important:

Some errors are indicated with a series of beep codes (see “Beep symptoms” on page 90).

Type 2254, 2256, 2257, 6336, 6337, 6339, 6341, 6342, 6346, 6347, 6348 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 “Setup Utility program” on page 10).

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.
