3Com NJ 90 Network Jack - Switch - 4 ports - EN, Fast EN - 10Base-T, 100Base-TX - panel-mountable
The 3Com NJ90 Network Jack is a low-cost, unmanaged switch that mounts in the wall, expanding one LAN wall outlet into four Fast Ethernet network connections. It increases the number of network ports available at the desktop - without the cost and inconvenience of running additional cables through walls and ceilings. Priced attractively, one 3Com NJ90 Network Jack costs a fraction of what you would spend on installing and activating four additional lines using Category 5 or 5e cabling. Historical buildings, solid-wall structures, and sites with asbestos insulation are great candidates for the network jack. Installed in a standard wall cutout, it's an elegant and reliable alternative to a freestanding switch, with significantly less risk of theft or damage. Different power options are available to meet a variety of installation needs, including a local AC power adapter and industry-standard P802.3af-compatible Power over Ethernet delivered over existing network cabling.
