3COM CORPORATION 3CNJ225 - 3Com IntelliJack NJ225 - Switch - 4 ports - EN, Fast EN - 10Base-T, 100Base-TX + 1x10/100BaseTX(uplink) 3CNJ225 INTELLIJACK NJACK 4PT 10/100 SWCH WM ONLYThe 3Com IntelliJack Switch NJ225 is a four-port, managed Fast Ethernet switch that can support VoIP, IEEE 802.1p Packet Prioritization, IEEE 802.1Q VLANs, and IEEE 802.3af Power over Ethernet. This "in the wall" solution mounts in BSI- or DIN-standard wall cutouts for a fraction of what it costs to run Category 5 or 5e cabling. The pass-through port can be used to add an analog voice or dedicated LAN line. The IntelliJack Switch NJ225 supports IEEE 802.1X network login for enhanced security. This SNMP-compatible switch includes capabilities for port-, unit-, and group-level administration. It's also enterprise-ready, supporting most management platforms such as 3Com Network Supervisor and HP OpenView. 3Com IntelliJacks are significantly less vulnerable to theft or damage than freestanding alternatives. They install without disturbing walls, ceilings, or day-to-day operations - making them ideal for hospitals, hotels, classrooms, historical buildings, conference rooms, and cubicles. Multiple power options including standard Power over Ethernet endspan switches and midspan solutions, and a local AC adapter, are sold separately. The NJ225 can also forward Power over Ethernet to another 802.3af-compatible device, such as a 3Com NBX Phone.
