Power over Ethernet (PoE) passes electrical power over the same Ethernet conductors as the data eliminating the need for a separate power cable. It’s a handy way to connect and power equipment such as IP cameras, IP telephones, routers, wireless access points and bridges. The PoE standard per IEEE 802.3at provides up to 15.4 watts of DC power to each device. The newer PoE+ or PoE plus standard offers up to 25.5 watts. PoE allows long cable runs up to 330 feet (100 meters). Managed PoE switches include Layer 2 functions like VLAN, QoS, IGMP, rapid spanning tree, redundancy and security. Select from 5 to 26 ports, copper or fiber connections and extended temperature.
