User Guide

The 3Com® Network Jack is a platform that provides
connectivity at the edge of the network infrastructure. The NJ95
Network Jack, is a member of this family of products.

The NJ95 Network Jack is a 4-port, un-managed Fast Ethernet
switch that fits into most standard data port openings. It has a
modular design consisting of a “main unit” and a “wall plate”.

The NJ95 Network Jack quadruples port connections where a
single port (and cable) already exists in the wall. Expanding port
connections with the 3Com Network Jack is a less expensive and
less disruptive alternative to running additional cabling. Also, the
3Com Network Jack is installed in the wall, making it more
secure and out of the way than deploying a remote desktop
switch.

The NJ95 Network Jack allows up to four networking devices,
such as computers, printers, Voice Over IP (VoIP) telephones, and
scanners, to be connected to the network via its own Ethernet
port. An optional port is available that allows an additional
device to be connected to a separate network segment through
the same NJ95.

The NJ95 needs no software to operate and no configuration. All
ports feature 10/100 Mbps auto-negotiation, which configures
the NJ95 Network Jack for 10 Mbps or 100 Mbps connections
automatically.

Before you begin installation, register your product at:
www.3com.com/support.

Appendix A: Detail Description of NJ95

Appendix A: Detail Description of NJ95

The NJ95 is a 4-port, un-managed Fast Ethernet switch that fits
into most standard data port openings. The NJ95 allows up to
four networking devices, such as computers, printers, Voice over
IP (VoIP) telephones, and scanners, to be connected to the
network via one Ethernet port. An optional connector is available
that allows an additional device to be connected to a separate
network segment through the same NJ95.

The NJ95 needs no software to operate and requires no
configuration. All ports feature 10/100 Mbps auto-negotiation,
which configures the NJ95 for 10 Mbps or 100 Mbps
connections automatically.

Power to the NJ95 can be provided in one of the following ways:

■

Power over Ethernet using an Integrated Switch

network via an integrated switch that supports IEEE

802.3af-compatible Power Over Ethernet (also known as In­line power, is a feature that provides power through an
Ethernet cable, allowing a device to receive both data and
power from the same network cable). See “Using an
Integrated Switch with Power over Ethernet” on page 24.

■

Power over Ethernet using a Midspan solution

network via an optional Multi-port or Single-port Ethernet
power supply. See “Using a Multi-port Ethernet Power
Setting up the Power Supply” on page 25 or “Using a
Single-port Ethernet Power Setting up the Power Supply”

Connecting Devices to the NJ95

After the NJ95 is installed, connect your networking devices
(such as computers, printers, etc.) to any of the four switched
ports on the front of the NJ95. If you installed the manufacturer­specific wall plate, you can connect to another device to the
optional port.

Using the 3Com Local Power Supply

If your network does not support Power Over Ethernet, or if you
are not using a single-port or multi-port Ethernet power supply,
you must purchase a local power supply from 3Com (see
“Obtaining Optional Components” in Appendix E). To use the
local power supply, make sure you have an electrical outlet near
the site where the NJ95 will be installed.

The network cabling at your site (from the wiring closet to the
wall or cubicle opening) may already be installed. If it is not,
install the cabling following these general guidelines.

CAUTION: It is recommended that a professional cable
installer perform these procedures. Be sure to adhere to
local safety and regulatory codes during the cable
installation.

1 Connect one end of an Ethernet cable to your network.

Usually, this connection is done in a network wiring closet,
via the patch panel.

2 Terminate the other end of the cable at the location where

the NJ95 is being installed using a female RJ-45 connector.
Refer to the connector manufacturer’s instructions for
terminating the cable. Be sure to test the connector and
verify it is working.

To ensure proper horizontal cabling functionality, adhere to the
following network cabling standards during installation:

■ ANSI/TIA/EIA-568 Commercial Building Telecommunications

■ The other end of the network cable is plugged into a

system that provides Power over Ethernet according to
IEEE 802.3af, if using Power over Ethernet.

■ The Local Power Supply is plugged into the NJ95 and

into a working electrical outlet, if using Local power
supply.

■ Verify the NJ95 is connected to the network properly by

viewing the Link LED (it should be lit). If the Link LED is not
lit, make sure the network cable:

■ Is terminated properly. Refer to the connector

manufacturer’s instructions for terminating the cable. Be
sure to test the connector and verify it is working.

■ Has a valid connection to the network.

■ Adheres to proper length and cabling specifications for

your network.

■ Make sure the port on the switch to which the NJ95 is

connected is configured as a standard MDI-X port. Make
sure all cables connecting the NJ95 to the patch panel are
straight-through cables (not crossover cables).
