PoE izwi kandi nka Power hejuru ya Ethernet (PoL, Imbaraga hejuru ya LAN) cyangwa Ethernet ikora, cyangwa rimwe na rimwe nkububasha kuri Ethernet.
Porogaramu zisanzwe kuri PoE zirimo gukurikirana umutekano, terefone ya IP, hamwe n’ahantu hatagaragara (WAP).Igikoresho cyakira cyangwa hagati cyakoreshejwe mugutanga amashanyarazi nibikoresho byo gutanga amashanyarazi (PSE) .Umutwaro uhujwe na Ethernet uhuza ni ibikoresho bitanga amashanyarazi (PD).
Porotokole ya PoE yo kugenzura imbaraga zumutwaro hagati ya PSE na PD isobanurwa na IEEE 802.3bt.Transformator irakenewe kuri port ya Ethernet yakira, midspan, hamwe na hub kugirango bazane amakuru mumurongo.Mubyongeyeho, voltage ya DC irashobora gukoreshwa kuri kanda yo hagati ya transformateur itagize ingaruka kubimenyetso byamakuru.Kimwe n'umurongo uwo ari wo wose wohereza amashanyarazi, iryo koranabuhanga rikoresha ingufu zingana cyane (hafi 50V) kugira ngo igumane hasi kandi igabanye ingaruka z'igabanuka rya voltage ya IR ku murongo, bityo bikomeza kugeza amashanyarazi ku mutwaro.Ikirangantego 2-insinga PoE itanga hafi 13W kuri PDs yo mucyiciro cya 1 na hafi 25.5W kugeza mucyiciro cya 2 PD, mugihe PoE isanzwe ya 4-insinga PoE izashobora gutanga hafi 51W kuri PD yo mucyiciro cya 3 na hafi 71W kugeza kuri 4 PDs.
