FRU Replacement

Strategy

Before

Replacing

Parts

Ensure that all diskette fixes are installed prior to

replacing

any

FRUs

listed

this

manual.

Use the following strategy to prevent unnecessary FRU replacement and service expense:

If you

are

instructed

replace a

FRU

and

that

does

not

correct

the

problem,

reinstall

the

original

FRU

before

you continue

Some

computers

have

both

processor

board

and

system

board.

If you are instructed to replace either

the

processor

board

the system

board,

and

the first

board that you replaced does not correct the problem,

reinstall the original board, then replace the other

(processor

system)

board.

Ÿ If an adapter or device

consists of more than one

FRU,

error

code may be caused by any of the

FRUs.

Before

replacing

the

adapter

device,

remove

the

FRUs,

one

one,

see

the

symptoms

IBM Corp.

1999

change. Replace only the FRU that changed the symptoms.

	Attention
	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

run a

low-level

format

before

replacing

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

overwritten if

you select an incorrect drive.

How

Use

Error

Messages:

Use the error

codes

displayed

the

screen to

diagnose

failures.

If more

than

one

error

code

displayed,

begin

the

diagnosis

with

the

first

error

code.

The

cause of the first error code can

result

false

error

codes

being

displayed.

error code

is displayed, see if the error symptom

listed

the

Symptom-to-FRU Index for

the

computer

you

are

servicing.

How

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

this

index.

Some

digits will represent different information

for

SCSI

errors

versus non-SCSI errors.

The following example shows which digits display the

shorter POST error messages and also defines the SCSI

information

an eight-digit error message.

Shorter POST Messages

"""""""""""""""""""""

" " " " "

"""""""""""""""""""""""""""""""""""""""""

" ð " ð " ð " ð " ð " ð " ð " ð "

Reserved "

Size (SCSI)

"""""""""""

" Slot Number (SCSI)

Device Code

Logical Unit Number (SCSI)

ID (SCSI)

All SCSI

devices

are

set

a different SCSI ID. Duplicate

SCSI

settings

can generate a false error message. Use

the

SCSI

Safety Notice 7

Though main batteries have low voltage, a shorted or grounded battery can produce enough current to burn combustible materials or personnel.

Bien que		le voltage des batteries principales soit peu
élevé, le court-circuit ou la mise à la masse d'une
batterie peut produire suffisamment de courant pour
brûler des matériaux combustibles ou causer des
brûlures		corporelles	graves.
Obwohl Hauptbatterien eine niedrige Spannung
haben,	können sie doch bei Kurzschluß			oder Erdung
genug Strom abgeben, um brennbare Materialien zu
entzünden oder Verletzungen bei Personen
hervorzurufen.
Sebbene le batterie di alimentazione siano a basso
voltaggio,		una batteria in corto circuito o a massa può
fornire corrente sufficiente da bruciare materiali
combustibili o provocare ustioni ai tecnici di
manutenzione.
Aunque	las	baterías	principales tienen	un voltaje bajo,
una batería cortocircuitada o con contacto a tierra
puede producir la corriente suficiente como para
quemar	material combustible o provocar quemaduras
en el	personal.

any

heavy

object:

Ensure

you

can

stand

safely

without

slipping.

Distribute the weight of the object equally

between

your

feet.

Use

slow lifting force. Never move suddenly or

twist

when

you

attempt

to lift.

Lift by standing or by pushing up

with

ŸReinstall all covers correctly before returning the machine to the customer.

Electrical Safety: Observe the following rules when working on electrical equipment.

	Important

Use	only	approved tools and test equipment. Some
hand	tools		have handles covered	with a soft	material
that does not insulate you when working with live
electrical		currents.
Many customers have, near their				equipment, rubber
floor mats that contain small conductive fibers to
decrease		electrostatic discharges. Do not use this type
of	mat to		protect yourself from	electrical	shock.

ŸFind the room emergency power-off (EPO) switch,

disconnecting switch, or				electrical outlet. If an
electrical accident occurs, you can then operate the
switch	or	unplug	the power cord		quickly.
Ÿ Do not	work	alone	under	hazardous	conditions or


near equipment				that	has		hazardous voltages.
Ÿ Disconnect		all	power		before:
–	Performing		a	mechanical			inspection
–	Working	near		power		supplies
–	Removing	or		installing		main units

Ÿ Before you start to work on	the machine, unplug the
power cord. If you cannot	unplug it, ask the customer
General	Descriptions11

to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.

ŸIf you need to work on a machineexposedthat has

electrical circuits, observe the following precautions:

–Ensure that another person, familiar with the power-off controls, is near you.

Attention: Another person must be there to switch off the power, if necessary.

–Use only one hand when working with

powered-on electrical equipment;

keep

the

other

hand in your pocket or behind your back.

Attention:

There

Handling Electrostatic Discharge-Sensitive

Devices: Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur

when there is a difference in charge between objects.

General Descriptions13

Protect against ESD damage by					equalizing		the charge			so
that the machine, the part,					the	work mat, and			the	person
handling the		part	are all	at	the	same	charge.
	Notes
	Notes
1. Use product-specific ESD procedures								when they
	exceed	the	requirements		noted here.
2. Make sure that the				ESD	protective			devices	you
	use have been certified (ISO 9000)							as fully
	effective.

When handling ESD-sensitive parts:

ŸKeep the parts in protective packages until they are

inserted into the product.

ŸAvoid contact with other people.

ŸWear a grounded wrist strap against your skin to

eliminate static on your body.

ŸPrevent the part from touching your clothing. Most

clothing

mat

to provide

a static-free work surface. The mat is especially

useful

when

handling

ESD-sensitive

devices.

Ÿ Select a grounding system,

such
