TheKusintha kwa PoEndi chosinthira chomwe chimathandizira magetsi ku chingwe cha netiweki.Poyerekeza ndi chosinthira wamba, cholumikizira magetsi (monga AP, kamera ya digito, ndi zina zotero) sichiyenera kuyimitsidwa ndi mawaya amagetsi, ndipo kudalirika kwa netiweki yonse ndikokwera.
Kusiyana pakati pa ma switch a PoE ndi masiwichi wamba
PoE switch ndi yosiyana ndi lophimba wamba, kusintha kwa PoE sikungopereka ntchito yotumizira ya switch wamba, komanso kupereka mphamvu zamagetsi kumapeto ena a chingwe chaukonde. imagwira ntchito moyenera), koma sichimalumikizidwa ndi magetsi, koma yolumikizidwa ndi chosinthira wamba kudzera pa chingwe cha netiweki.Pankhaniyi, kamera sikugwira ntchito.Ngati kamera sichikulumikizidwa ndi magetsi, koma chingwe chake chotumizira ma netiweki chimalumikizidwa ndi switch ya PoE, kamera imatha kugwira ntchito bwino.
PoE imagawidwa kukhala yokhazikika komanso yopanda muyezo.Woyengayo awona ngati zida zolumikizidwa ndi netiweki zili ndi poE polandila mphamvu.Ngati ilipo, idzayendetsedwa, ngati sichoncho, sichidzagwiritsidwa ntchito ndikungopereka kutumiza deta.Zomwe sizili zoyenera zidzaperekedwa mwachindunji ndi mphamvu.Ngati ulalowu sunapezeke, zida zitha kutenthedwa.
POE kusintha luso ndi ubwino
Pali miyezo iwiri ya masiwichi akuluakulu a PoE pamsika, IEEE802.3af ndi 802.3at, omwe amatanthauzira mphamvu yamagetsi ya 15.4W ndi 30W, koma chifukwa cha kutayika kwa njira yotumizira, magetsi enieni ndi 12.95W. ndi 25.5W, voliyumu yake ndi DC 48v.
Mukamagwiritsa ntchito kusintha kwa PoE komwe kumathandizira muyezo wa IEEE802.3af, mphamvu ya chipangizo chamagetsi sichikhoza kupitirira 12.95W;mofananamo, pogwiritsa ntchito kusintha kwa PoE kwa muyezo wa IEEE802.3at, mphamvu ya chipangizo chamagetsi sichikhoza kupitirira 25.5W.
Nthawi zambiri, chosinthira cha PoE chomwe chimathandizira IEEE802.3af/panthawi yomweyo, magetsi amatha kusintha.Mwachitsanzo, ngati ilumikizidwa ndi chipangizo cha 5W, imapereka mphamvu ya 5W;ngati chikugwirizana ndi 20W chipangizo, ndiye amapereka 20W mphamvu.
Ma switch a PoE ndi masiwichi omwe amathandizira magetsi ku zingwe za netiweki.Poyerekeza ndi masiwichi wamba, ma terminals (monga ma APs, makamera a digito, ndi zina zambiri) safunikira kukhala ndi mawaya kuti apereke magetsi, ndipo ndi odalirika pa intaneti yonse.TheKusintha kwa PoEsangathe kupereka ntchito kufala kwa lophimba wamba, komanso kupereka mphamvu kotunga ntchito kumapeto ena a chingwe maukonde.
Chipangizo chakumbuyo cha PoE chimangofunika chingwe chimodzi cha netiweki, chomwe chimasunga malo ndipo chimatha kusunthidwa mwakufuna (chosavuta komanso chosavuta), kupulumutsa ndalama.
Malingana ngati kusintha kwa PoE kulumikizidwa ku UPS, kumatha kupereka mphamvu kuzipangizo zonse zakumbuyo za POE pamene mphamvu yazimitsidwa.Ogwiritsa ntchito amatha kusakaniza ndi kusakaniza zida zoyambirira ndi zida za PoE pamanetiweki, ndipo zida izi zitha kukhala limodzi ndi zingwe za Ethernet zomwe zilipo.
