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

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 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.
