3Com Network Jacks Family Overview

Innovative "In the Wall" Switches for Network Growth!
3Com® Network Jacks expand LAN connectivity "in the wall" without disturbing wall spaces. Each network jack quickly and easily converts a one-port Ethernet wall outlet into four switched LAN connections. Ideal for older buildings or other hard-to-wire facilities, network jacks help reduce installation costs in almost any network environment—including small-office or enterprise businesses, government offices, dormitories, hospitals, K-12 classrooms, universities, laboratories, public kiosks, conference rooms, and shared office spaces.

These unique "in the wall"switches support VoIP, 10/100 Ethernet, Power over Ethernet, and local AC power. The 3Com NJ200 Network Jack offers advanced switching features, bundled management utilities, and VLAN support. The 3Com® NJ100, NJ90, and NJ95 Network Jacks are economical, unmanaged alternatives for sites not needing central control. The 3Com NJ100 Network Jack Power over Ethernet Bundle includes a P802.3af (draft)-compatible inline power source.
