Checking

the

indicator

lights

The

controller

unit

indicator

lights

(see

Figure

31

on

page

48)

display

the

status

of

the

controller

unit

and

its

components.

Green

indicator

lights

mean

normal

operating

status;

amber

indicator

lights

mean

a

possible

failure.

It

is

important

that

you

check

all

the

indicator

lights

on

the

front

and

back

of

the

controller

unit

when

you

turn

on

the

power.

After

you

turn

on

the

power,

the

indicator

lights

might

blink

intermittently.

Wait

until

the

controller

unit

completes

its

power

up

before

checking

for

faults.

It

can

take

up

to

15

minutes

for

the

battery

to

complete

its

self-test

and

up

to

24

hours

to

fully

charge,

particularly

after

an

unexpected

power

loss

of

more

than

a

few

minutes.

Perform

the

following

steps

to

check

the

controller

unit

indicator

lights

and

operating

status.

1.

To

view

the

indicator

lights,

remove

the

controller

unit

bezel.

2.

Check

the

indicator

lights

on

the

front

of

the

controller

unit.

3.

Check

the

indicator

lights

on

the

back

of

the

controller

unit.

4.

Check

the

indicator

lights

on

the

mini

hubs.

5.

If

all

indicator

lights

show

a

normal

status,

replace

the

bezel;

otherwise,

run

the

storage

management

software

to

diagnose

and

repair

the

problem.
