About the NJ205 IntelliJack
The 3Com NJ205 is part of the IntelliJack family of products that
provides connectivity at the edge of the network infrastructure.
The NJ205 IntelliJack is a 4-port, un-managed Fast Ethernet
switch that fits into most standard data port openings.
The NJ205 IntelliJack quadruples port connections where a single
port (and cable) already exists in the wall. Expanding port
connections with the 3Com IntelliJack is a less expensive and less
disruptive alternative to running additional cabling. Also, the
3Com IntelliJack is installed in the wall, making it more secure
and out of the way than deploying a remote desktop switch.
The NJ205 IntelliJack 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. A pass-through port is provided that allows an additional
device to be connected to a separate network segment through
the same IntelliJack.
All ports feature 10/100 Mbps auto-negotiation, which
configures the NJ205 IntelliJack for 10 Mbps or 100 Mbps
connections automatically.
The NJ205 needs no software to operate and no configuration.
However, to modify the default configuration and utilize the
advanced feature we have provided a configuration manager
software suite on compact disk.

4
Choose one pair of the provided screws that best fits your
outlet box.
Tighten the screws while holding the IntelliJack in place.
NOTE: The IntelliJack is designed to be mounted
using the provided mounting plate or many after-
market faceplates. However, some after-market
faceplates stand out from the wall and do not
provide a secure mounting surface for the IntelliJack.
In such cases it is recommended to place the 3Com
spacer between the IntelliJack and the after-market
face plate. For more information on the different
mounting plates and spacers, see Appendix B.

Connecting Devices to the IntelliJack
Once the power source and the data source have been verified in
good working order and the IntelliJack has been installed and
mounted, connect your networking devices (such as computers,
printers, IP phones, cameras, etc.) to the IntelliJack.
The IntelliJack has two ways to connect devices:
1
RJ-45 Personal Area Network (PAN) Ports — any of the four
switched ports on the bottom of the IntelliJack. All ports feature
10/100 Mbps auto-negotiation, which configures the NJ205
IntelliJack for 10 Mbps or 100 Mbps connections automatically.
2
Pass-through port—a single pass-through port is provided
that allows an additional device to be connected to a
separate network segment through the same IntelliJack. The
data or voice traffic that travels through the pass-through
port, passes through the IntelliJack without being switched.

Configuration Managers
Once you have installed the NJ205 hardware, you need to
configure it for use on your particular network. To configure the
NJ205, install the Local and Central Configuration Managers.
NOTE: You will use the Local Configuration
Manager for initial configuration of the NJ205
on your network. It is usually easiest if you load
this software on a laptop and use it to configure
NJ205 devices as you install them.
The NJ205 Central Configuration Manager is
used for advanced configuration and
management of one or more NJ205 devices on
your network. This software should be installed
on the machine you plan to use to manage your
NJ205 devices from a remote location—perhaps
the same console you use for SNMP
management.

Configuration Manager
You should use the Local Configuration Manager to initialize
each of the NJ205 IntelliJacks installed on your network. Once
you have completed that step, you can manage all of them with
the Central Configuration Manager.
Install this program on any computer on your network you want
to use as a central management console. (See the previous
chapter, “Installing the Configuration Managers,” for help). You
can use the same machine that has your SNMP-based
management platform. The Central Configuration Manager will
be able to configure and manage all of the IntelliJacks that reside
on your network.
Discovering NJ205 Devices on Your Netw ork
In order to manage the NJ205 IntelliJacks on your network, the
Central Configuration Manager needs to include them in its
database. The easiest way to add new NJ205 IntelliJacks to the
database is to use the device discovery tool included in the
Central Configuration Manager. The first time you run the
Central Configuration Manager, it will automatically take you to
the Discovery window as shown under step one below.

NOTE: VLAN stands for Virtual Local Area
Network. VLANS are used to create a subgroup
of systems within a LAN in order to isolate
traffic between network devices. The NJ205
supports VLAN tagging, but does not route
inbound traffic on a per-port basis.
If you change your VLAN settings, they should

authorization. Dated proof of purchase from 3Com or its authorized reseller may be
required. A User Service Order (USO), Return Material Authorization (RMA) or Service
Repair Order (SRO) number will be issued. This number must be marked on the
outside of the package sent to 3Com’s Corporate Service Center. The product must
be packaged appropriately for safe shipment and sent prepaid. It is recommended
that returned products be insured or sent by a method that provides for tracking of
the package. Responsibility for loss or damage does not transfer to 3Com until the
returned item is received by 3Com. 3Com will retain risk of loss or damage until the
item is delivered to Customer. For non-US Customers, the word 'prepaid' shall be
omitted where this requirement is not permitted by law. The allocation of
responsibility for loss or damage stated shall be subject to any mandatory legal
requirements. 3Com shall not be responsible for any software, firmware,
information, or memory data of Customer contained in, stored on, or integrated
with any products returned to 3Com for repair, whether under warranty or not.
