of

less

than

38

mm

(1.5

in.).

Installing

SFP

modules

The

DS4100

host

ports

require

SFP

modules.

SFP

modules

are

used

to

convert

electrical

signals

to

optical

signals

that

are

required

for

fibre

channel

transmission

to

and

from

RAID

controllers.

The

DS4100

supports

two

types

of

SFP

modules:

one

with

a

plastic

latch

and

one

with

a

wire

latch.

After

you

install

the

SFP

modules,

you

use

fiber-optic

cables

to

connect

the

DS4100

to

other

fibre

channel

devices.

Before

you

install

SFP

modules

and

fiber-optic

cables,

read

the

following

information:

v

Do

not

mix

long-wave

SFPs

and

short-wave

SFPs

on

a

single

storage

server.

Use

either

long-wave

SFPs

or

short-wave

SFPs.

You

can

use

the

DS4000

Storage

Manager

client

to

view

the

storage

subsystem

profile

in

order

to

verify

that

you

are

not

mixing

long-wave

and

short-wave

SFPs.

v

The

SFP

module

housing

has

an

integral

guide

key

designed

to

prevent

you

from

inserting

the

SFP

module

improperly.

v

Use

minimal

pressure

when

you

insert

the

SFP

module

into

a

port.

Forcing

the

SFP

module

into

a

port

could

cause

damage

to

the

SFP

module

or

the

port.

v

You

can

insert

or

remove

the

SFP

module

while

the

port

is

powered

on.

v

The

operational

loop

performance

is

not

affected

when

you

install

or

remove

an

SFP

module.

v

You

must

insert

the

SFP

module

into

a

port

before

you

connect

the

fiber-optic

cable.

v

You

must

remove

the

fiber-optic

cable

from

the

SFP

module

before

you

remove

the

SFP

module

from

the

port.

See

for

more

information.

To

install

an

SFP

module,

complete

the

following

steps.

Statement

3:

CAUTION:

When

laser

products

(such

as

CD-ROMs,

DVD

drives,

fiber-optic

devices,

or

transmitters)

are

installed,

note

the

following:

v

Do

not

remove

the

covers.

Removing

the

covers

of

the

laser

product

could

result

in

exposure

to

hazardous

laser

radiation.

There

are

no

serviceable

parts

inside

the

device.

v

Use

of

controls

or

adjustments

or

performance

of

procedures

other

than

those

specified

herein

might

result

in

hazardous

radiation

exposure.
