The 3Com NJ220 IntelliJack is a 4-port, managed Ethernet switch that fits into any standard electrical wall outlet or data port opening. It brings switching capabilities to any single port on an Ethernet network by allowing you to connect up to four networking devices, such as computer, printers, and Voice Over IP (VoIP) telephones to the network via one Ethernet port. You can use optional connectors to connect one or two additional devices to separate network segments through the same IntelliJack. All ports feature 10/100 Mbps auto-negotiation.

THE

NJ220 I

NTELLI

ACK

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 optional single-port or multi-port Ethernet power supply

Locally via an optional 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 NJ220 is ideally powered by a switch or other Power Sourcing Equipment (PSE) that is IEEE

802.3af-compatible. The NJ220 can also be powered by some switches which are not 802.3af-compatible. Consult the 3Com web site for more information.

You can manage the NJ220 IntelliJack using the included Central Configuration Manager or Web Configuration Manager. You can also use a supported SNMP management console as you would with any managed device on your network, but greater management and control is available through the Configuration Manager software. Management features include:

5 Mount the plate to the IntelliJack using the two adapter plate screws provided.

Installing the IntelliJack 9

Planning the Installation When installed, the back of the IntelliJack extends into a wall or cubicle opening

1.5 inches. Because the depth of some wall and cubicle openings differ, observe the following requirements and recommendations before installing the IntelliJack:

• Make sure the wall or cubicle opening where the IntelliJack is being installed

complies with the NEMA-WD6 standard, as described below.

• Make sure the distance between the back of the IntelliJack and the inside of

the wall or cubicle opening is at least 1.5 inches (3 inches is recommended).

NOTE: Some cubicle openings have a depth of 1.2 inches. In this case, install the IntelliJack using the extension ring (available for purchase separately; see “Obtaining Optional Components” on page 4) to obtain the minimum 1.5-inch depth.

If installing into a wall junction box, make sure there is enough space between the back of the IntelliJack and the inside of the junction box to maintain an acceptable bend radius on the cable. If you encounter interference or need additional clearance between the IntelliJack and where it sits inside the junction box, use the extension ring.

• To ensure proper horizontal cabling functionality, adhere to the following

network cabling 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

10 CHAPTER 1: INSTALLING THE NJ220 INTELLIJACK

Setting up the Network

Cabling at Your Site

Connecting the

IntelliJack to the

Network

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 performs 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 IntelliJack is being

installed (using either a female or male 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.

The method for connecting the IntelliJack to the network is determined by how your network cable is terminated (as described in the previous section, “Setting up the Network Cabling at Your Site”).

• If the end of the cable is terminated with a female RJ-45 connector, use the

RJ-45 coupler cable included in the package to connect the IntelliJack to the network cable (recommended installation.)

Installing the IntelliJack 11

• If the end of the cable is terminated with a male connector, connect the

network cable directly into the Ethernet uplink port.

Mounting the IntelliJack After connecting the IntelliJack to the network, use the two provided screws to

mount the IntelliJack in any standard NEMA-WD6 cubicle opening or wall outlet.

If the cubicle or wall opening has a depth of fewer than 1.5 inches, does not support the NEMA-WD6 standard, or does not have pre-drilled screw holes, mount the IntelliJack using the extension ring, as shown below.

NOTE: The extension rings are designed to stack on top of one another. If you need more than 0.3 inches of clearance, simply snap an additional extension ring to the back of the IntelliJack.

CAUTION: Make sure the vents along the edges of the IntelliJack faceplate are clear of any obstructions. If necessary, install the extension ring on recessed openings to allow airflow to vents.

12 CHAPTER 1: INSTALLING THE NJ220 INTELLIJACK

Connecting the Local

Power Supply (Optional)

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” on page 4). To connect the local power supply to the IntelliJack, please follow these steps:

1 Route the power cable through the strain relief of the IntelliJack (as shown in the

diagram below).

2 Securely mount the IntelliJack on a wall.

3 Plug the power cable into the IntelliJack. 4 Secure the local power supply and cable to the wall.

Installing the Web Configuration Manager

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.

NJ220 IntelliJacks are capable of being discovered and managed through a standard web browser. The Web Configuration Manager lets you access and control IntelliJacks from any Web-enabled computer on your network.

In order to enable the Web Configuration Manager you will need the following:

• A servlet-compliant web server or stand alone servlet engine

• Internet Explorer 6.0 or later; Netscape 7.0 or later web browser

• NJ220 Installation CD

The following instructions assume a scenario where the operating system being used is Microsoft Windows 2000 and the servlet engine is Apache Tomcat, Version 4.1. You may have to slightly alter this process if your specific environment is different. Note that Apache Tomcat requires Sun Microsystems’ Java Development Kit (JDK) 1.4. These are available at no charge from Sun.
