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.

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
4. Attach the Wall-Mount Brac ket
Attach the included wall-mount bracket to the wall opening as s ho w n in this
diagram.

5. Set Up the Network Cabling
The network cabling (from the wiring closet to the wall opening) may already be
in s t a ll e d. If it is not, ins t al l the cabling following these general guidelines.
CAUTION: HP recommends that a professional cable installer perform these
procedures. Be sure to adhere to local safety and regulatory codes during the cable
installation.1
Connect oneendof an Ethernet cable to the network. Usually, this
connection is made in anetwork wiring closet, via the patchpanel.
2 T e rmin a t e the other endof the cable at the locationwherethe
NJ1000G is being installed (using eithera female or male RJ-45
connector). Refer to the connector manufacturer's instructions for
terminating the cable. Be sure to testthe connector and verify that it
is work ing.
6. Connect the NJ1000G to the Ne twork
The method for connecting the NJ1000G to the network is determined by how
the network cable is terminated, as described in step 5.
If the endof the cable is terminatedwith a female RJ-45connector, use one of
the RJ-45coupler cables included in the NJ1000G package to connect the
NJ1000G to the network cable.

12
If the endof the cable is terminatedwith a male connector, connect the network
cable directly into the Ethernet uplink po rt.
7. Mount the NJ1000G to the W all
After you connect the NJ1000G to the network, follow these steps, as shownin
the next figure:
1Mount the NJ1000G to the wall-mount bracket.
CAUTION: Make sure that the vents alongthe edges of the NJ1000G faceplate
are clear of any obstructions to allow airflow to vents.
2 Slide the NJ1000G onto the wall-mount bracket, en s uring that the
fo ur hooks on the bracket fit into the four slots on the back of the
NJ1000G.

13
3 Pull the NJ1000G down to lockthe hooks tightly into the slots. Be
sure to matchthe screwholes in the bracket andthe NJ1000G .
Secure the NJ1000G u s ing the T-10 torx screw that came in the
NJ1000G package
8. Connect the Local Power Supply (O pti onal)
If the network does not support PoE, you can use the optional local power supply. T o
connect the local power supply to the NJ1000G, follow these steps:
1 Connect the round connector of the local power supply to the
NJ1000G (as shownin the next diagram).
2 Plug the power cord of the local power supply into an AC ou tlet.
WARNING: Use only the local power supply available from HP. Failure to do so
may result in damage to the NJ1000G or may result in a hazardous situation.

14
9. Connect Devices to the NJ1000G
Now you may c onnec t networking devices such as computers, servers, access points,
IP cameras, and Voice Over IP (VoIP) telephones to any of the four LAN ports on the
front of the NJ1000G. Remember, if power is supplied to the NJ1000G by802.3at or
via the local, external power supply, then PoE PSE power will be available on ports1
and
2.
10. Troubleshooting: Check the LEDs
Verify the NJ1000G installation by checking the LEDs according to this table:
