Strategy

for

replacing

FRUs

Before

replacing

parts

Make

sure

that

all

diskette

fixes

are

installed

before

replacing

any

FRUs

listed

in

this

manual.

Use

the

following

strategy

to

prevent

unnecessary

expense

for

replacing

and

servicing

FRUs:

v

If

you

are

instructed

to

replace

a

FRU

but

the

replacement

does

not

correct

the

problem,

reinstall

the

original

FRU

before

you

continue

.

v

Some

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

replacing

one

of

them

does

not

correct

the

problem,

reinstall

that

board,

and

then

replace

the

other

one.

v

If

an

adapter

or

a

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:

The

setup

configuration

on

the

computer

you

are

servicing

may

have

been

customized.

Running

Automatic

Configuration

may

alter

the

settings.

Note

the

current

configuration

settings

(using

the

View

Configuration

option);

then,

when

service

has

been

completed,

verify

that

those

settings

remain

in

effect.
