Notes:

1.

Damaged

data

in

CMOS

can

cause

undetermined

problems.

To

reset

the

CMOS,

remove

the

battery

for

15

minutes,

and

then

reinstall

the

battery.

2.

Damaged

data

in

BIOS

code

can

cause

undetermined

problems.

v

Flash

the

system

with

the

latest

BIOS

code.

v

If

the

system

appears

inoperative,

recover

the

BIOS

(see

“Recovering

the

BIOS

code”

on

page

30).

Check

the

LEDs

on

all

the

power

supplies

of

the

BladeCenter

unit

where

the

blade

server

is

installed.

If

the

LEDs

indicate

the

power

supplies

are

working

correctly,

and

reseating

the

blade

server

does

not

correct

the

problem,

complete

the

following

steps:

1.

Check

that

the

front

panel

is

connected

to

the

system

board.

2.

If

no

LEDs

on

the

front

panel

are

working,

replace

the

front

panel;

then,

try

to

turn

on

the

blade

server

from

the

BladeCenter

web

interface

(see

the

BladeCenter

documentation

for

more

information).

3.

Turn

off

the

blade

server.

4.

Remove

the

blade

server

and

remove

the

cover.

5.

Remove

or

disconnect

the

following

devices

(one

at

a

time)

until

you

find

the

failure

(reinstall,

turn

on

and

reconfigure

the

blade

server

each

time):

v

I/O

adapter

v

Drives

v

Memory

modules

(minimum

requirement

=

two

256

MB

DIMMs)

The

following

components

are

required,

at

a

minimum,

for

the

blade

server

to

operate:

v

System

board

v

One

microprocessor

v

Memory

(with

a

minimum

of

two

256

MB

DIMMs)

v

A

functioning

BladeCenter

6.

Install

and

turn

on

the

blade

server.

If

the

problem

remains,

suspect

the

following

FRUs

in

the

order

listed:

v

DIMM

v

System

board

v

Microprocessor

Notes:

1.

If

the

problem

is

solved

when

you

remove

an

I/O

adapter

from

the

blade

server

and

replacing

that

I/O

adapter

does

not

correct

the

problem,

suspect

the

system

board.

2.

If

you

suspect

a

networking

problem

and

the

blade

server

passes

all

the

system

tests,

suspect

a

network

cabling

problem

external

to

the

blade

server.

tips

Because

of

the

variety

of

hardware

and

software

combinations

that

can

be

encountered,

use

the

following

information

to

you

in

problem

determination.

If

possible,

Failure

symptom:

–

Does

the

server

fail

the

diagnostics

tests?

–

What,

when,

where,

single,

or

servers?

–

Is

the
