Power

cabling

The

DS4100

base

storage

server

uses

two

standard

power

cords,

and

the

single-controller

storage

server

uses

only

one.

You

can

connect

the

power

cords

to

a

primary

power

unit

inside

the

rack

cabinet,

such

as

a

properly

grounded

ac

distribution

unit,

or

to

an

external

source,

such

as

a

properly

grounded

electrical

outlet.

The

DS4100

storage

server

does

not

ship

with

power

cords.

Refer

to

for

the

list

of

IBM-approved

power

cords

for

your

region.

Depending

on

your

model,

the

DS4100

storage

server

does

ship

with

one

or

two

line

jumper

cords

for

connecting

the

DS4100

power

supply

or

power

supplies

to

an

IBM-approved

rack

power

distribution

unit.

If

you

have

not

already

done

so,

attach

the

power

cords

by

using

for

the

location

of

the

component

parts.

Perform

the

following

to

cable

the

power

cords:

1.

Connect

the

power

cord

to

the

power

supply.

2.

Remove

the

nut

that

holds

the

power

cable

strain-relief

clamp,

and

then

remove

the

strain-relief

clamp.

3.

Wrap

the

strain-relief

clamp

around

the

power

cord

approximately

20

cm

(8

in.)

from

the

power

supply

connection

end.

Leave

some

slack

between

the

clamp

and

the

power-supply

end

of

the

power

cord.

4.

Replace

the

power

cable

strain-relief

clamp,

and

tighten

it

securely

with

the

nut.

5.

Plug

the

power

cord

into

a

properly

grounded

electrical

outlet.

Note:

To

maintain

power

redundancy,

plug

the

storage

server’s

right

and

left

power

supplies

into

two

independent

external

power

circuits

through

ac

distribution

units

inside

a

rack

cabinet

or

directly

into

external

receptacles.

Similarly,

the

right

and

left

power

supplies

of

the

DS4000

storage

expansion

units

attached

to

the

DS4100

should

be

plugged

into

the

same

two

independent

external

power

circuits

as

the

DS4100.

It

is

recommended

that

you

determine

the

maximum

surge

current

possible

when

all

devices

in

the

power

circuit

are

started

at

the

same

time.

Based

on

the

total

number

of

devices

on

a

power

circuit,

find

the

maximum

(worst-case)

specification

value

in

order

to

prevent

the

circuit

from

tripping.

When

both

power

supplies

are

connected

and

the

storage

server

is

powered

on,

each

power

supply

unit

will

handle

approximately
