Overview of the NJ1000G and Its Features
The front of the NJ1000G has four gigabit LAN ports for local switching. The gigabit
LAN uplink port on the rear connects it to the rest of the network.
The NJ1000G brings gigabit switching capabilities to any single port on an
Ethernet network by allowing connections for up to four networking devices such
as

3
computers, servers, access points, IP cameras, and Voice Over IP (VoIP) telephones to
the network through a single Ethernet connection.
All 5 LAN ports feature 10/100/1000 Mbp s with auto-negotiation and auto MDI-X.
The NJ1000G also provides two p a ss -thr ough ports that can be used to connect
two additional devices to separate network segments through the same un it.
Power is provided to the NJ1000G either through the uplink port via 802.3at or
802.3af PoE(Power over Ethernet) or locally via anoptional, external 48V DC power
supply, 3CNJ1000GPSL.
NOTE: Power Over Ethernet (PoE) is amethodfor providing powerto equipment over
an E t her net cable, allowing a device to receive both dataandpower from the same
network cable. PoE power may be provided on port 1 or port 2 of the NJ1000G if
there is sufficientpower available to the system. See the section “Under s t a nd the PoE
Ca pa bili t i e s for P o rt 1 and Por t 2” laterin thi s guidefor details.

the end of this guide. F or the safety of people andequipment,onlyprofessional
network personnel s hould install the NJ1000G .
WARNING: Toavoid possibleinjury or damage to equipment, you must
use power supplyequipment that issafety certified according to UL, CSA,
IEC, or other applicable national or international safetyre qui re ment s for the
country of use. All references to power supply in this document refer to
equipment meeting these requirements.
Check the Shipment
The NJ1000G is available in single- and20-unit packs. Make sure that you have
the following items, which are included with each NJ1000G:
NJ1000G
 Screw kit for wall mounting the NJ1000G
 Male-to-male RJ-45coupler cable (2 per NJ1000G ) for connecting the Ethernet
cable from the network to the NJ1000G. NOTE: For use onlyif the network
cable is terminatedwith a f e ma le RJ-45 connector.
The following optional items in Table 3 may be u s eful, depending on your specific
installation requirements andthe PoE capability of yournetwork. If you choose to use
any of t h ese items, be sure that they are on handbefore you begin the installation.

Installation Overview for the NJ1000G
Detailed installation in struc t i ons are included in the sections that follow .
The following diagram displays an overview of the recommended installation. In this
example, the NJ1000G is being connected to an Ethernet network cable that is
terminatedwith a f e male RJ-45 connector.

1. Understand the Power Op ti on s
Power to the NJ1000G can be supplied through either PoE(either 802.3at or 802.3af)
applied to the uplink port or through the optional local external power supply.
If power is supplied to the uplink port by 802.3at or by the external power supply,
then ports1 and2 may act as PoE PSE (Power Source E quipment ) and may also
provide power to other devices pluggedinto those ports.If power is s upplied by
802.3af,then port 1 and2 will not be able to supply PoE power. Refer to Table 4 for a
summary of this in for mation.
Table 4

802.3at Ye s
Local E x ternal P ower Ye s
802.3af No
2. Under s ta nd the PoE Capabilities for Port 1 and Port 2
If power is supplied by 802.3at through the uplink port (PD) or if power is supplied
through the external power supply, then ports1 and2 may in turn act as PoE PSE and
may provide power.
If power is provided to the NJ1000G by the uplink port (PD) with 802.3at PoE or
with the external power supply, then the NJ1000G will have atotal PoE PSE budget
of
15.4W, which can be divided betweenport 1 and port 2 based on the class-based
power management feature.
The NJ1000G can power these combinations of devices:
 One Class 0,3 PD device or
 Two Class 2 PD devices or
 Two Class 1 PD devices or

9
 One Class 1 PD device and One Class 2 PD device
CAUTION: Youmust use onlya power supply that is provided or approved by HP for
use with this NJ1000G. Failure to comply with this requirement may result in damage
to the NJ1000G, or may result in a hazardous situation or personal injury.
3. Plan the Installation
When installed, the back of the NJ1000G extends into a wall for 0.5 inches.
Because the depth of some wall openings differs, observe the following
requirements and recommendations beforeyou install the NJ1000G :
Make sure that the wall openingwherethe NJ1000G is being in s t alled
complies with the NEMA-WD6 standard, as described in this diagram:
1.75 0”
(44.45mm)
2.8125 ”
(71.44 mm) 3.2812
5”
(83.31mm)
re f eren c e
Screw ho les
Make sure that the distance betweenthe back of the NJ1000G andthe inside
of the wall is at least 1.5 inches (3 inches is recommended).

10
NOTE: If you are installing the NJ1000G into a wall junction box, make sure that
there is enough space between the back of the NJ1000G and the inside of the
junction box to maintainan acceptable bend radiu s on the cable.
 To ensure properhorizontal cabling functionality, adhere to the following
network cabling s t andar d s during installation:
ANSI/TIA/EIA-568
Commercial Building Telecommunications Cabling Standard
 ANSI / TIA/E I A-569
Commercial Building Standard for Telecommunications Pathways andSpaces
