n Configuration Manager software.
Planning the Installation Because the depth of some wall and cubicle openings differ, observe the following
requirements and recommendations before installing the IntelliJack:
• Ensure there is enough volume in the wall opening to accommodate fiber
cables.
• Ensure there is clearance around the unit for proper cooling.
• The NJ240FX has been designed for installation into wall or cubicle openings
that conform to NEMA standards.
• Make sure the distance between the back of the IntelliJack and the inside of
the wall or cubicle opening is at least 25mm to maintain an acceptable bend
radius on the cable.
• To ensure proper horizontal cabling functionality, adhere to the following
standards during installation:
n ANSI/TIA/EIA-568
Commercial Building Telecommunications Cabling Standard
n ANSI/TIA/EIA-569
Commercial Building Standard for Telecommunications Pathways and
Spaces
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.
NOTE: 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.

Supply
Power to the IntelliJack Switch NJ240FX is provided via AC power. It has an
internal power supply that can accept 100~240V AC power. A power connector
is supplied that can be securely plugged into the unit.
CAUTION: The supplied AC power cable is the only approved power cord that
can be used with the unit and is required to maintain proper strain relief of the
assembly and AC power cord.
Before connecting the IntelliJack to the network, verify that the existing network
cabling is connected to an active fiber port.
Instructions for unpacking and mounting the NJ240FX.
1 Remove the unit from its protective anti-static bag.
6 CHAPTER 1: INSTALLING THE NJ240FX INTELLIJACK
2 Remove any shipping tape from the unit and separate the metal plate from the
main unit. Separate the plastic housing cable tray from the main unit by sliding it
downward towards the four downstream ports and then away from the main
unit.
3 Route the two fiber cables through the rectangular opening directly above the UP
arrow indicator from the backside of the metal mounting plate (side opposite the
metal mounting post). Pull through enough cable to allow yourself room to
terminate the connections.
4 Route both fiber optic cables through the rectangular opening in the plastic
housing cable tray.
5 Attach both fiber optic cables to the fiber transceiver module located on the
backside of the main unit.
6 Route the two fiber cables around the cable management feature approximately
one turn until you end up in the area with no guide tabs.
7 Plug the supplied AC power cable into the mating plug on the backside of the
main housing.
Mounting the IntelliJack 7
8 Reassemble the plastic cable tray to the main housing in the reverse order from
step 2.
NOTE: Care should be taken when reassembling the plastic cable tray to the
main housing so as not to damage the four installation guide hooks.
9 If the pass-thru feature is required, route the existing female RJ45 connector and
cable through the same rectangular opening in the metal mounting plate. Again
ensure you have allowed yourself enough room to terminate the connection.
10 If the pass-thru cable feature is required, connect the male RJ45 connector to the
existing female RJ45 connector.

13 Align the main housing mounting hole with the metal mounting boss on the
metal mounting plate and secure with the supplied long oval head machine screw.
NOTE: An access hole is provided for installations that require the supplied AC
power cord to be routed back into the NEMA box. Place the AC power cord
between the metal and plastic housing cable tray and route through the lower
rectangular opening in the metal mounting plate. Adjust cable for desired loop
length before securing in place.
Connecting Devices to the NJ240FX
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 NJ240FX 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.

System Requirements The machine you install the software on should meet the following requirements:
C
ONFIGURATION MANAGERS
Once you have installed the NJ240FX hardware, you need to configure it for use
on your particular network. To configure the NJ240FX, install the Local and
Central Configuration managers.
NOTE: You will use the Local Configuration Manager for initial configuration of
the NJ240FX on your network. It’s usually easiest if you load this software on a
laptop and use it to configure IntelliJacks as you install them.
The NJ240FX Central Configuration Manager is used for advanced
configuration and management of one or more NJ240FXs on your network.
This software should be installed on the machine you plan to use to manage
your NJ240FXs from a remote location—perhaps the same console you use for
SNMP management.
• Pentium processor
• Minimum of 15MB disk space
• Windows 2000, Windows XP Pro (required for IPv6 support), or Windows NT
4.0 with Service Pack 6 installed (While Windows 95 and Windows 98 are not
recommended operating systems for use with management platforms, the
Configuration Manager software may work with them.)
NOTE: The NJ240FX is designed with a dual mode IP stack. The unit can accept
and respond to commands over IPv4 or IPv6. The mode of operation of the
Central Configuration Manager will determine whether specific IPv4 or IPv6
parameters are displayed and can be configured by the CCM.
12 CHAPTER 2: INSTALLING THE CONFIGURATION MANAGERS
Installing the Local and Central Configuration Managers
Run the following steps to install the Configuration Manager software:
1 Insert the NJ240FX CD into your Windows 2000, Windows XP Pro, or Windows
NT computer.
2 If your computer is configured to Auto-Play CDs, the installation will start
automatically. If not, double-click the setup.exe icon on the CD.
3 Click Next to continue.
4 Carefully read the license agreement. If you agree, select “I accept the terms in
the license agreement” and click Next to continue.
5 The installation will present Readme Information. This is also found in the
Readme.txt file on the installation CD. Please read the information and click Next
to continue.
6 Enter your user and organization names. You can also specify whether you want
the management programs to be available to just you or to anyone that may use
the computer you’re installing these applications on. Select the option you prefer
and click Next.
NOTE: If you have a previous version of the Central Configuration Manager
installed in another directory, you will lose access to any database or log files
that are stored there. Prior to completing the installation, you should copy these
files to the same directory into which you plan to install the configuration
software.
7 The program files will be installed in the directory C:\Program
Files\3Com\IntelliJack. If you want to change the location of the installation, click
Change. Otherwise click Next to accept the default location and continue.
8 Select a typical or custom setup and click Next. The Typical installation will install
both the Local Configuration Manager and the Central Configuration Manager on
your system. The Custom installation option lets you install just one of the
programs if you wish.
9 Review the settings you selected and click Install.
10 When the installation has completed, click the Finish button to close the
installation utility.
The installation utility will create two shortcut icons on the Desktop--one for the
Local Configuration Manager and one for the Central Configuration Manager.
You can also launch the programs from a program group you can access from the
Start menu. The program group folder is labeled 3Com IntelliJack and can be
found under the Programs menu.
USING THE
3
Initializing the IntelliJack
LOCAL CONFIGURATION MANAGER
Once you have installed the NJ240FX hardware on your network and the Local
Configuration Manager software on your computer, you need to perform an
initial configuration of the IntelliJack.
1 The first step is to connect your computer to the NJ240FX that you are installing.
Attach an Ethernet cable from a computer running the Local Configuration
Manager software to any one of the four personal area network (PAN) ports on
the front of the NJ240FX.
2 Click on the desktop shortcut icon labeled IJ Local Config Mgr to start the
program. When it launches, you will see a window like this:
3 Select the type of IntelliJack switch you would like to manage.
4 Enter the password for the device. The default password is “password” (without
the quotes). You will have the opportunity to specify a new password from within
this application.
5 Select the transport mode you are using to communicate on your network. The
IPv6 option will only be enabled if your operating system supports IPv6.
(IntelliJacks prior to NJ240FX do not support IPv6.) The Interface number
corresponds to the network interface in the computer running the LCM
14 CHAPTER 3: USING THE LOCAL CONFIGURATION MANAGER
application. If this computer has more than one network interface, it may be
necessary to specify the correct interface number. You can use the Windows
IPCONFIG DOS command to assist you in determining the correct interface
number.
6 Click OK, and you will see this window:
7 The MAC address, Serial Number, and Firmware Version of the currently
connected NJ240FX will appear at the top of the window. If you connect to
another NJ240FX, you must click the Query button to refresh the window.
If you are not connected to any IntelliJacks, the MAC address field will display the
message Not Connected. If the Not Connected message appears, check your
connection to the IntelliJack and click the Query button.
8 Make sure the General tab is selected.
9 Enter Location Information for the NJ240FX you are currently 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 128 characters), but we
recommend that you enter a logical, easy to follow description, such as “Building
A, 3rd floor, room 315, West wall.”
10 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.
11 Select the method the NJ240FX should use to obtain an IP address. The NJ240FX
can either get an IP address from an existing DHCP server on your network, or you
can specify an address. If you elect to specify your own address, you should enter
Setting Advanced Options 15
the IP Address, Subnet Mask, and Default Gateway information in the appropriate
fields.
NOTE: By default, the NJ240FX is configured to automatically obtain an IP
address from a DHCP server. If no DHCP server exists, or if the NJ240FX cannot
obtain an IP address, it will default back to its previously configured static IP
address. If it had previously been assigned an IP address, it will default to that
one. If it did not, it will default to the static IP address of 192.168.1.252.
12 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.
13 Click the Configure button. Any changes you specify are sent to the NJ240FX and
will become effective immediately.
Setting Advanced Options
Those are the only steps required to initialize your NJ240FX.
If you want to change the default password of the NJ240FX or change SNMP
community strings, you can configure these settings from either the Local
Configuration Manager or the Central Configuration Manager (covered in the
next chapter). In the Local Configuration Manager, both settings are found under
the Advanced tab.
16 CHAPTER 3: USING THE LOCAL CONFIGURATION MANAGER
1 Select the Advanced tab on the IntelliJack Local Configuration Manager window.
2 To change the IntelliJack’s configuration password, click on the box next to
Change Password. Then enter the new password in both password fields. (You
must enter the password twice to ensure you type it correctly.) The password you
select can be any combination of letters and numbers between 8 and 32
characters.
3 To configure the NJ240FX 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.
Note that this only applies to SNMP v1. If you are using SNMP v3, you will need to
create SNMP profiles using the Central Configuration Manager.
4 Click the Configure button. The changes are sent to the NJ240FX 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.
USING THE
4
Discovering IntelliJacks on Your Network
CENTRAL CONFIGURATION MANAGER
You should use the Local Configuration Manager to initialize each of the
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 chapter 2, “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.
We recommend that you keep the Central Configuration Manager (CCM) running
on your machine. Information such as traps and alerts are sent to the CCM on a
periodic basis. If you shut off the machine or close the configuration manager, you
will not be able to receive this information.
In order to manage the IntelliJacks on your network, the Central Configuration
Manager needs to include them in its database. The easiest way to add new
IntelliJacks to the database is to use the device discovery tool included in the

1 When you launch the Central Configuration Manager, you will see a welcome
window like this one:
You should select the type of IntelliJack switch you would like to manage with the
CCM software. If you are managing an NJ240FX IntelliJack, then enter the
password (“password” by default) you specified when you first installed the
IntelliJack switch. Entering a password is not required to communicate with other
IntelliJacks.
Next select the IP transport you will use for communication on your network. The
IPv6 option will only be enabled your operating system supports IPv6. (IntelliJacks
prior to NJ240FX do not support IPv6.)
The interface number corresponds to the network interface in the computer
running the CCM application. If this computer has more than one network
interface, it may be necessary to specify the correct interface number. You can use
the Windows IPCONFIG DOS command to assist you in determining the correct
interface number.
The CCM can only manage one type of IntelliJack switch at a time (i.e., either
NJ240FX or NJ220). To switch between managing these two types of IntelliJacks
without exiting the CCM, select CCM Settings from the View menu to display the
CCM session configuration window. From here you can make the necessary
changes. If you decide to change the type of IntelliJack that is being managed, you
must re-discover the IntelliJacks on your network. If you want to change the IP
transport used, you must restart the CCM.

IPv4 mode and you have previously discovered IntelliJacks:
If the CCM is operating in IPv6 mode, it will look like this:
