What is power over Ethernet (PoE)?

PoE is the delivery of electrical power to networked devices over the same data cabling that connects them to the LAN. This simplifies the devices themselves by eliminating the need for an electric plug and power converter, and makes it unnecessary to have separate AC electric wiring and sockets installed near each device. PoE’s use has grown substantially since the IEEE standardized it in 2003. Dell’Oro group says that PoE port shipments will total over 624 million over the next five years.
