Chapter 1. Introduction

Important service information

Important

BIOS and device driver fixes are

customer-installable. The BIOS and device drivers

are posted on the IBM support site

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

Advise customers to contact the PC Company

HelpCenter at 800-772-2227 if they need assistance

in obtaining or installing any diskette fixes.

FRU replacement strategy

Before replacing parts

Ensure that all BIOS and device driver fixes are

installed before 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, but the

replacement 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 replace does not correct the problem, reinstall

the original board, and then replace the other (processor

or system) board.

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

any of the FRUs may be the cause of the error. 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.

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); then,

when service has been completed, verify that the

settings are in place.

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. If you select an incorrect drive,

data or programs can be overwritten.

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. Whatever causes the

first error code may also cause false error codes. 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 have one meaning for

SCSI errors and a different meaning for non-SCSI errors.

The following example shows which digits display the

shorter POST error messages and also defines the SCSI

information in each digit of an eight-digit error message.

Shorter POST Messages

Reserved

Device Code

00000000

ID (SCSI)

Logical Unit Number (SCSI)

Slot Number (SCSI)

Size (SCSI)

Each SCSI device is assigned a unique SCSI ID. Duplicate

SCSI ID settings can generate a false error message. Use

the SCSI ID to determine whether an error message is

coming from an internal or an external device.

Safety notices: multilingual translations

The following safety notices are provided in English,

French, German, Italian, and Spanish languages.

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.

Safety Notice 2

Some standby batteries contain a small amount of

nickel and cadmium. Do not disassemble it,

recharge it, throw it into fire or water, or short-circuit

it. Dispose of the battery as required by local

ordinances or regulations. Use only the battery in

the appropriate parts listing. Use of an incorrect

battery can result in ignition or explosion of the

battery.

Certaines batteries de secours contiennent du nickel

et du cadmium. Ne les démontez pas, ne les

rechargez pas, ne les exposez ni au feu ni àl’eau.

Ne les mettez pas en court-circuit. Pour les mettre

au rebut, conformez-vous àla réglementation en

vigueur. Lorsque vous remplacez la pile de

sauvegarde ou celle de l’horloge temps réel, veillez

àn’utiliser que les modèles cités dans la liste de

pièces détachées adéquate. Une batterie ou une

pile inappropriée risque de prendre feu ou

d’exploser.

Die Bereitschaftsbatterie, die sich unter dem

Diskettenlaufwerk befindet, kann geringe Mengen

Nickel und Cadmium enthalten. Sie darf nur durch

die Verkaufsstelle oder den IBM Kundendienst

ausgetauscht werden. Sie darf nicht zerlegt,

wiederaufgeladen, kurzgeschlossen, oder Feuer

oder Wasser ausgesetzt werden. Die Batterie kann

schwere Verbrennungen oder Verätzungen

verursachen. Bei der Entsorgung die örtlichen

Bestimmungen für Sondermüll beachten. Beim

Ersetzen der Bereitschafts- oder Systembatterie nur

Batterien des Typs verwenden, der in der

Ersatzteilliste aufgeführt ist. Der Einsatz falscher

Batterien kann zu Entzündung oder Explosion

führen.

Alcune batterie di riserva contengono una piccola

quantitàdi nichel e cadmio. Non smontarle,

ricaricarle, gettarle nel fuoco o nell’acqua né

cortocircuitarle. Smaltirle secondo la normativa in

vigore (DPR 915/82, successive disposizioni e

disposizioni locali). Quando si sostituisce la batteria

dell’RTC (real time clock) o la batteria di supporto,

utilizzare soltanto i tipi inseriti nell’appropriato

Catalogo parti. L’impiego di una batteria non adatta

potrebbe determinare l’incendio o l’esplosione della

batteria stessa.
