Introduction

Important Service Information

Important

Diskette fixes are customer-installable. The diskette

fixes are posted on the IBM support site

http://www.pc.ibm.com/support/ .

Advise customers to contact the IBM

HelpCenter

at 800-772-2227 if they need assistance in obtaining

or installing any diskette fixes.

Customers in Canada should call IBM

HelpCenter

at 800-565-3344 for assistance or download

information.

FRU Replacement Strategy

Before Replacing Parts

Ensure that all diskette fixes are installed prior to

replacing any FRUs listed in this manual.

Use the following strategy to prevent unnecessary FRU

replacement and service expense:

vIf you are instructed to replace a FRU and that does

not correct the problem, reinstall the original FRU

before you continue.

vSome computers have both a processor board and a

system board. If you are instructed to replace either the

processor board or the system board, and the first board

that you replaced does not correct the problem, reinstall

the original board, then replace the other (processor or

system) board.

vIf an adapter or device consists of more than one FRU,

an error code may be caused by any of the FRUs.

Before replacing the adapter or device, remove the

FRUs, one by one, to see if the symptoms change.

Replace only the FRU that changed the symptoms.

vR31 : When CPU is replaced, the heat sink should be

replaced with new one also.

Attention: A customized setup configuration (other than

default settings) may exist on the computer you are

servicing. Running Automatic Configuration may alter those

settings. Note the current configuration settings (using the

View Configuration option) and verify that the settings are

in place when service is complete.

Hard Disk Drive Replacement Strategy

Always try to run a low-level format before replacing a hard

disk drive.

Attention: The drive startup sequence in the computer

you are servicing might have been changed. Be extremely

careful during write operations such as copying, saving, or

formatting. Data or programs can be over-written if you

select an incorrect drive.

How to Use Error Messages

Use the error codes displayed on the screen to diagnose

failures. If more than one error code is displayed, begin the

diagnosis with the first error code. The cause of the first

error code can result in false error codes being displayed.

If no error code is displayed, see if the error symptom is

listed in the Symptom-to-FRU Index for the computer you

are servicing.

How to Read POST Error Messages

POST error messages are displayed on the screen as

three, four, five, or eight digits. The error messages that

can be displayed as shorter POST messages are

highlighted in this index. Some digits will represent

different information for SCSI errors versus non-SCSI

errors.

All SCSI devices are set to a different SCSI ID. Duplicate

SCSI ID settings can generate a false error message. Use

the SCSI ID to determine whether the error message is

coming from an internal or an external device.

Drive and Diskette Compatibility Matrix

The following table provides identification information for

3.5-inch drives.

Diskette Drive Identifying Mark

Safety Notices (Multi-lingual

Translations)

page number reference to the appropriate multi-lingual,

translated safety notice found in this section.

The following safety notices are provided in English,

French, German, Italian, and Spanish.

Safety Notice 1

Before the computer is powered-on after FRU

replacement, make sure all screws, springs, or other

small parts are in place and are not left loose inside

the computer. Verify this by shaking the computer

and listening for rattling sounds. Metallic parts or

metal flakes can cause electrical shorts.

Avant de remettre l’ordinateur sous tension après

remplacement d’une unitéen clientèle, vérifiez que

tous les ressorts, vis et autres pièces sont bien en

place et bien fixées. Pour ce faire, secouez l’unitéet

assurez-vous qu’aucun bruit suspect ne se produit.

Des pièces métalliques ou des copeaux de métal

pourraient causer un court-circuit.

Bevor nach einem FRU-Austausch der Computer

wieder angeschlossen wird, muβsichergestellt

werden, daβkeine Schrauben, Federn oder andere

Kleinteile fehlen oder im Gehäuse vergessen

wurden. Der Computer muβgeschüttelt und auf

Klappergeräusche geprüft werden. Metallteile oder

-splitter können Kurzschlüsse erzeugen.

Prima di accendere l’elaboratore dopo che éstata

effettuata la sostituzione di una FRU, accertarsi che

tutte le viti, le molle e tutte le altri parti di piccole

dimensioni siano nella corretta posizione e non

siano sparse all’interno dell’elaboratore. Verificare

ciòscuotendo l’elaboratore e prestando attenzione

ad eventuali rumori; eventuali parti o pezzetti

metallici possono provocare cortocircuiti pericolosi.

Antes de encender el sistema despues de sustituir

una FRU, compruebe que todos los tornillos,

muelles y demás piezas pequeñas se encuentran

en su sitio y no se encuentran sueltas dentro del

sistema. Compruébelo agitando el sistema y

escuchando los posibles ruidos que provocarían.

Las piezas metálicas pueden causar cortocircuitos

eléctricos.
