Power over Ethernet

OverviewStandard implementationTechniquesStandards developmentUsesTerminologyPower management features and integrationNon-standard implementations

Standards-based Power over Ethernet is implemented following the specifications in IEEE 802.3af-2003 (which was later incorporated as Clause 33 into IEEE 802.3-2005) or the 2009 update, IEEE 802.3at. The standards require Category 5 cable or better for high power levels but allow using Category 3 cable if less power is required. In multi-pair cases, PoE supplies power as a common-mode signal over two or more of the differential pairs
