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.

Installing the IntelliJack
Installing the NJ205 IntelliJack consists of the following steps:
1 Set up the power supply.
2 Mount the NJ205 to the wall outlet box.
3 Connect devices to the NJ205.
4 Check the NJ205 LEDs.
Setting up the Power Supply
Power to the IntelliJack is provided through one of the following
methods:
■ Over the network via an integrated switch that supports
Power Over Ethernet.
■ Over the network via an Ethernet multi-port endspan power
supply.
■ Over the network via a single-port Ethernet power supply.
■ Locally via a 3Com local power supply.
NOTE: Power Over Ethernet, also known as in-line
power, is a method to provide power to equipment over
an Ethernet cable, allowing a device to receive both data
and power from the same network cable. The NJ205 is
ideally powered by a switch that is IEEE 802.3afcompliant. The NJ205 can also be powered by some
switches that are not 802.3af-compliant. Consult the
3Com web site for more information.
7
Installing the IntelliJack
Before you begin installation, determine which type of power
supply the IntelliJack will use. For more information on power
options and configuration, see Appendix D, “Power Options”.
Mounting the IntelliJack
The IntelliJack mounts in any standard British Standard Institute
(BSI): BS 4664:1970 (1986) single cubicle opening or wall outlet.
8
M ounting the IntelliJack
Before connecting the IntelliJack to the network, verify that the
existing network cabling meets the ANSI/TIA/EIA-568 standard
and that the port in the wiring closet is connected to an active
Ethernet MDI-X port.
1 Thread both IntelliJack LAN cables through the opening in
the mounting plate.
2 Connect the wiring as illustrated on page 8.
The IntelliJack has two Ethernet cables each terminated
with a male RJ-45 connector.
The white cable connects the LAN to the four personal
area network (PAN) ports located on the bottom of the
IntelliJack.
The black cable connects the LAN to the single passthrough port located on the front of the IntelliJack.
3 Choose one pair of the provided screws that best fits your
outlet box.
4 Tighten the screws while holding the IntelliJack in place.
NOTE: The IntelliJack is designed to be mounted
using the provided mounting plate or many aftermarket 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.

Installing the IntelliJack
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.

Installing the
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.
13
Installing the Configuration Managers
System Requirements
The machine you install the software on should meet the
following requirements:
■ Pentium processor
■ Minimum of 15MB disk space
■ Windows 2000 or Windows NT 4.0 with Service Pack 6
installed (Windows 95 and Windows 98 are not
recommended operating systems for use with management
platforms. In most cases, the Configuration Manager
software will work with Windows 95, 98, or XP. However,
please check 3Com’s web site for additional information
regarding XP support)

22
Initializing the NJ205 IntelliJack
5 Enter Location Information for the particular NJ205 you are
configuring. This field can help you and other network
managers identify this IntelliJack in the future. You may
enter any information you like (up to 256 characters), but
we recommend that you enter a logical, easy to follow
description, such as “Building A, 3rd floor, room 315, West
wall.”
6 Enter a Group Name for this IntelliJack. This can be any
name you wish. With the Central Configuration Manager,
you can perform management tasks on all IntelliJacks with
the same group designation.
7 Select the method the NJ205 should use to obtain an IP
address. The NJ205 can either get an IP address from an
existing DHCP server on your network or you can directly
specify the address. If you elect to specify your own
address, you should enter the IP Address, Subnet Mask, and
Default Gateway information in the appropriate fields.
NOTE: By default, the NJ205 is configured to
automatically obtain an IP address from a DHCP
server. If no DHCP server exists, or if the NJ205
cannot obtain an IP address, it will default to
the IP address 192.168.1.252.
23
Using the Local Configuration Manager
8 If you wish, check the box next to Lock IP Address. Selecting
this option will ensure that the IntelliJack will always use a
particular address.
WARNING: If you lock an IP address and
reserve it for this IntelliJack, make sure you
configure your DHCP server so it won’t
distribute that address to other devices.
9 Click the Configure button and the Local Configuration
Manager will ask you to enter the password for the device.
If you haven’t changed the password, you should enter the
default password, which is “password” (without the
quotes). Your changes are sent to the NJ205 and will
become effective immediately.
Those are the only steps required to initialize your NJ205
IntelliJack.
24
Setting Advanced Options
Setting Advanced Options
If you want to change the default password of the NJ205 or

password twice to ensure you entered it correctly.) The
password you select can be any combination of letters and
numbers between 8 and 32 characters.
3 To configure the NJ205 for management with an SNMP
console, select the SNMP Configuration box. Enter the GET
Community String and SET Community String in the
appropriate fields. Each field lets you enter any combination
of letters and numbers up to 32 characters.
4 Click the Configure button and the Local Configuration
Manager will ask you to enter the password for the device.
If you haven’t changed the password, you should enter the
default password, which is “password” (without the
quotes). Your changes are sent to the NJ205 and will
become effective immediately.
NOTE: You should change the password to
ensure that no one else can re-configure your
system. Make sure you remember the new
password you set. If you forget the new
password, you will not be able to perform
any other configuration tasks unless you
send the device back to 3Com.
26
5
Using the Central
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 Network
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.
27
Using the Central Configuration Manager
To discover devices on your network, run the following steps:
1 Open the Central Configuration Manager by doubleclicking on the NJ205 Central Config Mgr desktop icon.
When it launches, you will see a window similar to this one:
28
Discovering NJ205 Devices on Your Network
2 Select Discovery from the Devices menu. The following
window appears:
NOTE: The default subnets are the ones your
machine is connected to.
3 You can discover new devices based on a specific subnet or
on a specific range of IP addresses.
a To discover devices by subnet, select that option on the
screen. Click the Add button to add a new subnet to the
discovery list. The following box appears:
29
Using the Central Configuration Manager
b Fill in the Subnet and Mask fields and click OK.
or
c To discover devices within a certain IP range, select that
option on the screen and complete the From and To
fields.
4 If the box next to “Delete all devices in the existing list” is
checked, the discovery process will replace all of the devices
in your current database with the new devices it discovers.
If unchecked, the discovery process will add newly
discovered devices to the current database.
5 Click OK to start the discovery process.
30
Discovering NJ205 Devices on Your Network
The device discovery tool will return the following information
from the NJ205 IntelliJacks on your network:
■

Subnet address
Group Name
Location information
Firmware version
You can sort this information in ascending or descending order.
NOTE: Discovered devices are automatically
added to the default database. This default
database opens automatically when you launch
the Central Configuration Manager. If you like,
you can keep several database files, each with
its own list of devices. For example, you may
want a separate database for each subnet you
manage. To save a database file or open
another database file, select the Open Database
or Save Database As options from the File
menu.
You can view discovered devices many ways. On the left side of
the window, under the toolbar, you can see a drop down box
with options for either Subnet, Firmware Version, or Group
Name. The option you select in this box determines how the
views are displayed in the left pane of the window.
31
Using the Central Configuration Manager
When Subnet is selected (the default option), you will see a list
of IP subnets to choose from. Selecting Network will show all of
the discovered devices in the database. If you select a particular
subnet, only the devices in that subnet will be displayed.
When Firmware Ver is selected, you will see a list of the different
firmware versions loaded on the devices. This view is particularly
useful if you want to select only the devices with an old firmware
version so you can perform an upgrade.
When you select Group Name from the drop down list, the
Central Configuration Manager will present a list of the different
group names you have specified.

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.
74
F
Troubleshooting
If you encounter problems with the NJ205 IntelliJack:
■
■
Verify the IntelliJack is receiving power by viewing the
Power LED (it should be on). If the Power LED is not on,
make sure that:
■
(If using Power Over Ethernet) the other end of the
network cable is plugged into a switch on the network
that has Power Over Ethernet integrated into it, or one
that feeds into an external midspan power supply that
supports Power Over Ethernet.
■
(If using a local power supply) the power supply is
plugged into the IntelliJack and into a working electrical
outlet.
Verify the IntelliJack is connected to the network properly
by viewing the Link LED (it should be on). If the Link LED is
not on, 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.
