Recursos e Benefícios
Quadruple LAN Connectivity at the Wall The 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 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 isnt 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. The included management software provides port-level monitoring and central administration of the 3Com IntelliJack Switch NJ220. Advanced 10/100 switch features and SNMP compatibility enable network jacks to be discovered and controlled by standard enterprise management platforms-including 3Com Network Supervisor and HP OpenView.		Four 10/100 Mbps switched ports connect desktops, notebooks, printers, fax machines, or VoIP telephones; optional pass-through ports support telephony or additional networking Bundled central management capabilities help streamline IT administration and enhance data security Management GUIs offer fine control of a single port, as well as bulk administration for a group of network jacks The Location Mapping feature remotely locates any device on the network—a great advantage for troubleshooting Standards-based traffic prioritization, multicast rate control, and VLANs balance loads and boost security Security features include 802.1x Network Login, RADIUS support, MAC address filtering, traffic monitoring, SNMP traps, 802.1Q VLANs, and wall-mounted case Power over Ethernet lowers the risk of power interruptions; port #1 can forward power to another device Portable AC power supply for LANs without inline power capabilities is also convenient for installation and configuration Compliance with NEMA-WD6 and ANSI commercial building standards helps ensure easy installation
