    https://en.wikipedia.org/wiki/Power_over_Ethernet

    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.
    Power is supplied as a common-mode signal over two or more of the differential pairsof wires fou…

      Remote powering, such as Power over Ethernet (PoE), is a popular method of dc power delivery using communications cabling, with more than 100 million nodes installed around the globe. Power over Ethernet has evolved—from initially sourcing up to 15 watts at the power source equipment (PSE) as

      • During autonegotiation, the PD is signalling the PSE of how much wattage of power it requires. The below standards are the power in watts that the PSE will supply to PD based on its requirement: 1. PoE–IEEE 802.3af standard that supplies up to 15 watts of DC power from PSE and 12.95 watts from PD due to losses on an ethernet cable. It uses two pairs of wires like CAT…
