Intermittent Problems

Intermittent system hang problems can be caused by 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 recurring

problem exists.

When

analyzing

the

intermittent problem,

do

the

following:

1.

Run

the advanced diagnostic test for the system

board

in

loop

modeat least

10

times.

2.

If

no

error

is

detected,not replacedoany FRUs.

3.

If

any

error

is detected, replace the FRU

shown

by

the

FRU

code. Rerun

the

test

to

verify

that

no

more

errors

exist.

Undetermined Problems

You

are

here

because

the

diagnostic

tests

did

not

identify

which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate nondefective FRUs).

Verify that all attached devices are supported by the computer.
