Introduction to PoE

PoE technology allows IP telephones, wireless LAN access points, and other appliances to receive power and transfer data over existing ethernet LAN cabling. For more information about PoE technology, see the PoE/PoE+ planning and implementation guide, which is available on the Networking website at Enter your Switch number.

Additionally, PoE+ provides more power-management capability, allowing the switch to have more power available for more PDs. Power can be allocated exactly and automatically according to what the PD actually requires at a given time.
