Attention:

The

DS4100

single-controller

storage

server

does

not

support

hot-swap

RAID

controllers

or

power

supplies.

You

will

lose

access

to

data

if

you

attempt

to

remove

or

replace

a

functioning

(non-failed)

RAID

controller

or

power

supply

in

a

DS4100

single-controller

storage

server

without

first

powering

down

the

storage

server.

Hot-swap

drive

bays

The

hot-swap

drive

bays

that

are

accessible

from

the

front

of

your

storage

server

are

shown

in

Figure

2.

The

DS4100

supports

up

to

14

DS4000

1.5

Gbps

SATA

hard

disk

drives.

These

drives

are

preinstalled

in

drive

trays.

The

unit

consisting

of

the

drive

and

the

drive

carrier

assembly

is

called

a

drive

CRU.

The

SATA

drive

CRU

includes

the

drive

tray,

the

SATA

drive,

and

the

hard

disk

drive

(HDD)

interposer

card.

You

install

the

drive

CRUs

in

the

14

drive

bays

on

the

front

of

the

storage

server.

There

are

no

serviceable

parts

in

a

drive

CRU.

If

it

fails,

it

must

be

replaced

in

its

entirety

(drive,

interposer,

bezel,

and

tray).

Attention:

1.

Never

hot-swap

a

drive

CRU

when

its

associated

green

Activity

LED

is

flashing.

Hot-swap

a

drive

CRU

only

when

its

associated

amber

Fault

LED

lights

and

is

not

flashing

or

when

the

drive

is

inactive

and

its

associated

green

Activity

LED

lights

and

is

not

flashing.

2.

The

SATA

drive

and

its

HDD

card

are

digitally

signed

together

at

the

factory.

Do

not

swap

drives

and

interposers

between

drive

CRUs.

Do

not

replace

one

SATA

drive

with

another

SATA

drive.

These

actions

will

result

in

a

drive

CRU

that

cannot

be

recognized

by

the

storage

server

RAID

controller.

3.

After

you

remove

a

drive

CRU,

wait

at

least

70

seconds

before

replacing

or

reseating

the

drive

CRU

to

allow

the

drive

to

properly

spin

down.

Failure

to

do

so

may

cause

undesired

events.

Note:

If

the

hard

disk

drive

you

want

to

remove

is

not

in

a

failed

or

bypass

state,

always

use

the

DS4000

Storage

Manager

client

program

either

to

place

the

drive

in

a

failed

state

or

to

place

the

array

that

is

associated

with

the

drive

(or

drives)

in

an

offline

state

before

you

remove

the

drive

from

the

enclosure.
