When

 

this

 

LED

 

is

 

lit

 

and

 

not

 

flashing,

 

it

 

indicates

 

that

 

the

 

server

 

is

 

turned

 

on.

 

When

 

this

 

LED

 

is

 

flashing,

 

it

 

indicates

 

that

 

the

 

server

 

is

 

turned

 

off

 

and

 

still

 

connected

 

to

 

an

 

ac

 

power

 

source.

 

When

 

this

 

LED

 

is

 

off,

 

it

 

indicates

 

that

 

ac

 

power

 

is

 

not

 

present,

 

or

 

the

 

power

 

supply

 

or

 

the

 

LED

 

itself

 

has

 

failed.

 

 

If

 

this

 

LED

 

is

 

off,

 

it

 

does

 

not

 

mean

 

that

 

there

 

is

 

no

 

electrical

 

power

 

in

 

the

 

server.

 

The

 

LED

 

might

 

be

 

burned

 

out.

 

To

 

remove

 

all

 

electrical

 

power

 

from

 

the

 

server,

 

you

 

must

 

disconnect

 

the

 

power

 

cord

 

from

 

the

 

electrical

 

outlet.

 

 

 

Press

 

this

 

button

 

to

 

turn

 

the

 

server

 

on

 

and

 

off

 

manually.

 

A

 

power-control-button

 

shield

 

comes

 

installed

 

around

 

the

 

button

 

to

 

prevent

 

the

 

server

 

from

 

being

 

turned

 

off

 

accidentally.

 

You

 

can

 

remove

 

this

 

disk-shaped

 

shield

 

if

 

you

 

prefer.

 

 

 

Press

 

this

 

button

 

to

 

reset

 

the

 

server

 

and

 

run

 

the

 

power-on

 

self-test

 

(POST).

 

You

 

might

 

have

 

to

 

use

 

a

 

pen

 

or

 

the

 

end

 

of

 

a

 

straightened

 

paper

 

clip

 

to

 

press

 

the

 

button.

 

 

 

 

 

 

When

 

this

 

LED

 

is

 

flashing,

 

it

 

indicates

 

that

 

a

 

hard

 

disk

 

drive

 

is

 

in

 

use.

 

 

 

This

 

LED

 

can

 

be

 

lit

 

remotely

 

by

 

the

 

system

 

administrator

 

to

 

aid

 

in

 

visually

 

locating

 

the

 

server.

 

You

 

can

 

use

 

IBM

 

Director

 

to

 

light

 

this

 

LED

 

remotely.

 

 

 

When

 

this

 

LED

 

is

 

lit,

 

it

 

indicates

 

that

 

a

 

system

 

error

 

has

 

occurred.

 

An

 

LED

 

on

 

the

 

system

 

board

 

might

 

also

 

be

 

lit

 

to

 

help

 

isolate

 

the

 

error.

 

See

 

for

 

additional

 

information.

 

 

 

Connect

 

a

 

USB

 

device

 

to

 

either

 

of

 

these

 

connectors.

 

 

 

Press

 

this

 

button

 

to

 

release

 

a

 

CD

 

from

 

the

 

CD

 

drive.

 

 

 

 

 

When

 

this

 

LED

 

is

 

lit,

 

it

 

indicates
