Return

enclosure

to

fully

home

position

and

attach

to

rack

using

captive

fasteners

on

front

flanges.

Note:

Rack

rails

have

features

to

restrict

complete

enclosure

withdrawal

while

still

allowing

access

to

the

cooling

fans.

If

it

becomes

necessary

to

completely

remove

the

system,

pull

the

enclosure

out

until

it

stops

then

rotate

the

latches,

shown

in

Figure

15

(right

hand

up,

left

to

completely

remove

the

enclosure

from

the

Power

cord

connection

CAUTION:

The

power

connection

must

always

be

disconnected

prior

to

removal

of

a

PSU

from

the

enclosure.

To

connect

the

power

cord,

do

the

following:

1.

Observe

all

safety

and

ESD

precautions

listed

in

the

Safety

and

Warranty

Guide.

2.

Attach

a

power

cord

for

the

installed

PSU.

The

Power

On

LED

(see

for

the

PSU

will

blink

green

when

AC

main

power

is

present.

The

Power

Grounding

checks

The

SMC

-

Storage

Array

must

only

be

connected

to

a

power

source

that

has

a

safety

electrical

earth

connection.

CAUTION:

If

more

than

one

enclosure

is

installed

in

a

rack,

the

earth

connection

to

the

rack

is

even

more

important,

because

the

rack

will

have

a

high

“earth

leakage

current”

(“touch

current”).

Before

powering

on,

the

earth

connection

to

the

rack

must

be

checked

by

an

electrical

engineer

who

is

qualified

in

local

and

National

electrical

standards.
