Overview of the

NJ2000G

and Its Features

The

Installation Overview for the NJ2000G

Detailed installation instruc

ions are included

in the

sections

that

follow.

The

following

diagram displays

overview

of the

recommended

installation.

In this

example,

the

NJ2000G is

being

connected

to an

Ethernet

network

cable

that

terminatedwith a

female

-45

connector.

1. Understandthe Power Options

Power

to the

NJ2000G can

supplied

in one of

these

ways:

•

Through

PoE (either

802.3at or

802.3af) applied

to the uplink

•

Through

the optional

local external

power supply

If power is

upp

lied

to the uplink port by 802.3at or bythe

external

power

supply,

then

1 and 2

may

act

as PoE PSE

(Power

urce

Equipment)

and

may also provide

power to other

devices

plugged into

hos

ports.

If power is

upp

lied

by 802.3af, then port 1 and 2 will not be

able

to supply

PoE

power.

2. Understandthe

PoE Capabilities

for Port 1 and Port 2

If power is

upp

lied

by 802.3at through the uplink port

(PD)

or if power is

supplied

through the

external

power

supply,

then

1 and2

may

act

as PoE PSE

and

may provide

power.

If power

is provided

to the

NJ2000G

bythe uplink port

(PD)

with 802.3at

PoE

or with the

external

power

supply,

then the

NJ2000G

will

have

a total

PoE

PSE

budget of 15.4W, which

can

divided

betweenport 1 and port 2

based

the

class-based

power

management

feature.

The NJ2000G can

power

these combinations

of devices:

•

One Class

0,3

PD device

•

Two

PD devices

•

PD devices

•

One Class

CAUTION:

Youmust

use

supply

that

HPfor

use

with this

NJ2000G. Failure

comply

with this

requirement

may

result

damage

to the

NJ2000G,

may result

in a

hazardous

situation or

personal

injury.

Plan

the Installation

When

installed,

the

back

of the

NJ2000G extends

into a wall for 0.5

inch

es. Because

the depth of

some

wall

openings

differs,

observe

the

ollo

win

requirements

and

comm

dation

before you

install

the

NJ2000G

•

Make

sure

that the wall opening where the

NJ2000G is

being

installed

complies

with the

NEMA-WD6 standard, as described

in this

diagram:

•

Make

sure

that the

distance

betweenthe

back

of the

NJ2000G

and

the

inside

of the wall isat

least

1.5

inches

inches is

recommended).

NOTE:

If you

are installing

the

NJ2000G

into awalljunction box,

make sure

tha

there

enough

space

betweenthe

back

of the

NJ2000G

and the

inside

of the junction box to maintain an

acceptable

bend

radius

on the cable.
