The PoE Switch ONV-POE21004P-at provides power and data from a single point, using Power over Ethernet (PoE) over a single Cat-5 cable. The five Fast Ethernet ports can be used for any 10/100 Mbps link and four of these ports can supply industry-standard IEEE 802.3at power. Advanced auto-sensing algorithm gives power only to IEEE802.3at end devices, so no need to worry about damaging proprietary PoE or non-PoE equipment. In addition, it discontinues the power when PoE devices are disconnected. Easy and reliable, the PoE Switch ONV-POE21004P-at automatically determines PoE requirements, speed, duplex, and cable type using Auto Uplink™.
