Ndi kutchuka kochulukira kwa foni ya IP, kuyang'anira makanema apaintaneti ndi zida za Ethernet zopanda zingwe pamaneti, kufunikira kopereka chithandizo chamagetsi kudzera pa Ethernet palokha kukukulirakulira.Nthawi zambiri, zida zama terminal zimafunikira magetsi a DC, ndipo zida zogwiritsira ntchito nthawi zambiri zimayikidwa padenga kapena panja pamwamba kuchokera pansi.Ndizovuta kukhala ndi soketi yamagetsi yoyenera pafupi.Ngakhale pali socket, chosinthira cha AC / DC chofunidwa ndi zida zama terminal ndizovuta kuyika.Kuphatikiza apo, m'mapulogalamu ambiri akuluakulu a LAN, oyang'anira amafunika kuyang'anira zida zingapo nthawi imodzi.Zidazi zimafuna magetsi ogwirizana komanso kasamalidwe kogwirizana.Chifukwa cha kuchepa kwa malo operekera magetsi, zimabweretsa vuto lalikulu pakuwongolera magetsi.Ethernet magetsi a Poe amangothetsa vutoli.

Poe ndi ukadaulo wama waya wa Ethernet.Chingwe cha netiweki chomwe chimagwiritsidwa ntchito potumiza deta chimakhala ndi mphamvu yamagetsi a DC nthawi imodzi, yomwe imatha kuthetsa mphamvu yapakati yama terminal monga IP foni, opanda zingwe AP, chojambulira cham'manja, owerenga makhadi, kamera ndi kupeza deta.Poe magetsi ali ndi ubwino wodalirika, kugwirizana kosavuta ndi muyezo umodzi:

Zodalirika: chipangizo cha Poe chimatha kupereka mphamvu pazida zingapo nthawi imodzi, kuti athe kuzindikira magetsi apakati komanso kusunga mphamvu nthawi imodzi.Kulumikizana kosavuta: zida zama terminal sizifuna magetsi akunja, koma chingwe chimodzi chokha cha netiweki.Muyezo: tsatirani miyezo yapadziko lonse lapansi ndikugwiritsa ntchito mawonekedwe amphamvu a RJ45 ogwirizana padziko lonse lapansi kuti muwonetsetse kulumikizana ndi zida kuchokera kwa opanga osiyanasiyana.
