The 3CNJ220-CRM 3Com IntelliJack Switch NJ220 is an "in-the-wall," managed Ethernet switch that easily quadruples LAN infrastructure connections. Four switched ports and up to two pass-through ports connect a variety of devices via one wall outlet, making it more cost-effective than pulling additional wiring. This unique networking platform is ideal for hard-to-wire spaces such as asbestos-insulated walls, older buildings, dormitories, and modular cubicles
The 3CNJ220-CRM wall-mounted form factor is more secure than a freestanding hub or switch. The unit mounts inside the wall space, keeping the switch case and uplink port out of the way. A network jack isn't easily damaged or disconnected, nor will it "grow legs" and vanish. It provides unobtrusive and reliable connectivity for high-traffic locations such as classrooms, public kiosks, conference rooms, and shared office spaces.
