a FRU,

make sure the model of the com-

puter

and

FRU

part

number

are correct by

referring

to

the

FRU

parts

list.

Ÿ

A

FRU

should

not

be

replaced

because

of

a

single,

unreproducible

failure.

Single

failures

can

occur

for

a

variety

of

reasons

that

have

nothing

to

do

with a hardware defect, such as: cosmic radiation,

electrostatic discharge, or software errors. FRU

replacement

should

be

considered

only

when a

recur-

ring

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 non-defective FRU.
