PoE fasaha ce da ke ba da wutar lantarki da watsa bayanai ta igiyoyin sadarwa.Kebul na cibiyar sadarwa ɗaya kawai ake buƙata don haɗawa zuwa wurin kyamarar PoE, ba tare da buƙatar ƙarin wutar lantarki ba.
Na'urar PSE ita ce na'urar da ke ba da wutar lantarki ga na'urar abokin ciniki na Ethernet, kuma shine mai sarrafa dukkan ikon POE akan tsarin Ethernet.Na'urar PD ita ce nauyin PSE wanda ke karɓar iko, wato, na'urar abokin ciniki na tsarin POE, kamar wayar IP, kyamarar tsaro ta hanyar sadarwa, AP, mataimaki na dijital ko caja wayar hannu da sauran na'urorin Ethernet da yawa (a gaskiya, kowane). na'urar da ke da ƙarfin ƙasa da 13W na iya samun madaidaicin iko daga soket RJ45).Su biyun sun kafa haɗin bayanai dangane da ma'aunin IEEE 802.3af game da matsayin haɗin kai, nau'in na'ura, matakin amfani da wutar lantarki, da sauran abubuwan da ke karɓar ƙarshen na'urar PD, kuma suna amfani da wannan azaman tushen PSE don kunna PD ta hanyar Ethernet.
Lokacin zabar canjin PoE, ana buƙatar la'akari da waɗannan abubuwan:
1. Ƙarfin tashar jiragen ruwa guda ɗaya
Tabbatar da ƙarfin tashar jiragen ruwa guda ɗaya ya haɗu da matsakaicin ƙarfin kowane IPC da aka haɗe zuwa sauyawa ko a'a.Idan eh, zaɓi ƙayyadaddun ƙayyadaddun sauyawa bisa iyakar ƙarfin IPC.
Ikon PoE IPC na yau da kullun bai wuce 10W ba, don haka sauyawa kawai yana buƙatar tallafawa 802.3af.Amma idan buƙatar wutar lantarki na wasu injunan ƙwallon ƙwallon ƙafa ya kai kusan 20W, ko kuma idan ƙarfin wasu APs mara waya ya fi girma, to canjin yana buƙatar tallafawa 802.3at.
