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.
