Power over Ethernet
OverviewNon-standard implementationsTechniquesStandards developmentUsesTerminologyPower management features and integrationStandard implementation
There are more than ten proprietary implementations. The more common ones are discussed below. Some Cisco WLAN access points and VoIP phones supported a proprietary form of PoE many years before there was an IEEE standard for delivering PoE. Cisco''s original PoE implementation is not software upgradeable to the IEEE 802.3af standard. Cisco''s original PoE equipment is capable of delivering up to 10 W per port. The amount of power to be delivered is negotiated between the endpoi
