Power over Ethernet - PoE, IEEE802.3af standard

Power-over-Ethernet (PoE) is an emerging new technology that enables delivery of data and power to internet appliances over existing CAT-5 Ethernet cables. PoE is rapidly gaining in popularity with manufacturers and end users of devices such as VoIP phones, wireless access points, security cameras and point-of-sale terminals. PoE is governed by the standards defined in the recently ratified IEEE802.3af standard.
