Read FRU Removal and Replacement

procedures

before

replacing

any

FRUs.

Be

extremely

careful

during

write

operations

such as copying, saving, or formatting.

Drives

in

the computer that you are servicing

might have been rearranged or the drive start-up

sequence

might

have

been

altered. If you

select

an incorrect drive, data or programs might be

overwritten.

Replace

FRUs

only

for

the

correct

model.

When

you

replace

a

FRU,

make sure

the

model

of

the

machine

and

FRU part

number

are

correct

by

referring

to

the FRU

parts

list.

A

FRU

should

not

be

replaced

because

of

a

single,

unreproducible

failure.

Single

failures

can

occur

from

a

variety

of

reasons

that

have

nothing

to

do with a hardware problem, such as:

cosmic radiation, electrostatic discharge, or

software errors. FRU replacement should be

considered

only

when

a

recurring

problem

exists.

If

this

is suspected, clear the error

log

and run

the

test

again. Do

not

replace

any

FRUs

if

log

errors

do

not

reappear.

Be

careful

not

to

replace

a

nondefective

FRU.
