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 Planning and Implementation Guide, which is available on the HP Networking website at
Power-over-ethernet (PoE) and Power-over-ethernet plus (PoE+ or POEP) operate similarly in most cases. The CLI commands are the same for a PoE module or a PoE+ zl module. Any differences between PoE and PoE+ operation are noted; otherwise, the term "PoE" is used to designate both PoE and PoE+ functionality.
