FRU Replacement

Strategy

Before

Replacing

Parts

Ensure that all diskette fixes are installed p

replacing

any

FRUs

listed

this

manual.

Use the following strategy to prevent unnecessar replacement and service expense:

Ÿ	If	you	are instructed	to replace a FRU	and	that
	does	not	correct the	problem, reinstall	the	original
	FRU	before	you continue	.

ŸSome computers have both a processor board


system board. If you are instructed							to	re
the processor board or the system board,
board that you replaced does not correct
reinstall the original board, then replace th
(processor		or system)	board.
Ÿ If	an adapter or device consists					of	more
FRU, an error code may be caused by								any
FRUs. Before replacing the adapter or devi
remove the		FRUs, one	by	one,	to	see	if t
toms	change. Replace		only	the	FRU	that	chang
the	symptoms.

Introduction1

	Attention
	Attention
A customized setup configuration (other						than de
settings) may exist on the computer					you	are	se
Running Automatic Configuration may alter those							set
tings. Note the current configuration					settings		(u
the		View	Configuration option) and	verify		that t
tings		are	in place when service	is	complete.

Hard Disk Drive		Replacement	Strategy:
Always	try to	run a	low-level format before repla
disk	drive.

Attention

The drive startup sequence in the computer you servicing might have been changed. Be extremely careful during write operations such as copying saving, or formatting. Data or programs can be o written if you select an incorrect drive.

How to Use Error Messages

Use the error codes displayed on the screen

failures. If	more	than	one error code is displa
the diagnosis	with	the	first error code. The c

first error code can result in false error cod played. If no error code is displayed, see if symptom is listed in the Symptom-to-FRU Index for computer you are servicing.

How to Read POST Error Messages

POST error messages are displayed on the screen three, four, five, or eight digits. The error m can be displayed as shorter POST messages are h lighted in this index. Some digits will represent

information for SCSI	errors	versus non-SCSI errors.
The following example	shows	which digits display t

shorter POST error messages and also defines the information in an eight-digit error message.

Shorter POST Messages *3333-3333-3333-33330
