3Com® IntelliJack™ Switch Family

3Com IntelliJack switches are unique "in the wall" devices that quickly convert single port LAN wall outlets into four switched ports. They work in almost any network environment— including enterprise businesses, government offices, dormitories, hospitals, classrooms, laboratories, public kiosks, conference rooms, and shared office spaces. Unlike freestanding hubs or switches, these intelligent network jacks are not easily damaged or disconnected, and they are affixed to the wall for added physical security.

The IntelliJack Switch NJ220 comes with advanced switching, security, and management features, making it particularly suited for converged voice and data environments, with the added flexibility of optional pass-through connectivity and Power over Ethernet forwarding capabilities. The IntelliJack Switch NJ100 is similar to the NJ220 but without the enhanced security and remote management controls. The Network Jack NJ90 is 3Com's most economical solution for expanding a single LAN link into four autonegotiating 10/100 Mbps LAN ports.

3Com compatible power sources, which are required and sold separately, include inline Power over Ethernet and local AC adapters. For an integrated endspan solution, the 3Com SuperStack® 3 Switch 4400 PWR combines standard data switching and power injection in a single network appliance.
