NJ90 User Guide

The 3Com Network Jack is a platform that provides connectivity at the edge of the network infrastructure. The NJ90 Network Jack, is a member of this family of products.

The NJ90 Network Jack is a 4-port, un-managed Fast Ethernet switch that fits into most standard data port openings.

The NJ90 Network Jack quadruples port connections where a single port (and cable) already exists in the wall. Expanding port connec- tions with the 3Com Network Jack is a less expensive and less dis- ruptive 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 NJ90 Network Jack allows up to four networking devices, such as computers, printers, Voice over IP (VoIP) telephones, and scanners, each to be connected to the network via its own Ethernet port.

The NJ90 needs no software to operate and no configuration. All ports feature 10/100 Mbps auto-negotiation, which configures the NJ90 Network Jack for 10 Mbps or 100 Mbps connections automati- cally.
