3Com NJ90 Network Jack, Cream - 3CNJ90

Quadruple LAN Connectivity at the Wall!

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.

  • 3Com NJ90 Network Jack provides a low-cost, convenient alternative to running additional cables

  • Power over Ethernet provides configuration flexibility and reduces the risk of power interruptions; 3Com Network Jack AC Power Supply provides local power for LANs without inline power capabilities
  • Compliance with NEMA-WD6 and ANSI commercial building standards ensures easy installation in standard wall cutouts
