UwitekaGuhindura PoEni switch ishigikira amashanyarazi kumurongo.Ugereranije na switch isanzwe, ingufu zakira itumanaho (nka AP, kamera ya digitale, nibindi) ntabwo ikenera insinga kugirango itange amashanyarazi, kandi kwizerwa kwurusobe rwose ni hejuru.
Itandukaniro hagati ya PoE ihinduranya na basanzwe
PoE ihinduranya itandukanye na switch isanzwe, PoE switch ntishobora gutanga gusa uburyo bwo kohereza ibintu bisanzwe, ariko kandi itanga imikorere yo gutanga amashanyarazi kurundi ruhande rwumurongo wurusobe.Urugero, hariho kamera yo kugenzura ibyuma bya digitale (ikeneye amashanyarazi kuri kora mubisanzwe), ariko ntabwo ihujwe no gutanga amashanyarazi, ariko ihujwe na switch isanzwe ikoresheje umugozi.Muri iki gihe, kamera ntabwo ikora.Niba kamera idahujwe no gutanga amashanyarazi, ariko insinga yayo yohereza imiyoboro ihujwe na PoE switch, kamera irashobora gukora mubisanzwe.
PoE igabanijwemo ibisanzwe kandi bitari bisanzwe.Igisanzwe umuntu azamenya niba ibikoresho byumuyoboro uhujwe bifite imbaraga za PoE zakira.Niba ihari, izahabwa ingufu, niba atariyo, ntabwo izakoreshwa kandi itanga gusa ihererekanyamakuru.Ibitari bisanzwe bizahabwa imbaraga zitaziguye.Niba iyi link itamenyekanye, ibikoresho birashobora gutwikwa.
POE hindura ikoranabuhanga nibyiza
Hariho amahame abiri kubisanzwe byingenzi byahinduwe na PoE kumasoko, IEEE802.3af na 802.3at, bisobanura ingufu zitanga amashanyarazi ya 15.4W na 30W, ariko kubera igihombo mugikorwa cyo kohereza, amashanyarazi nyirizina ni 12.95W na 25 ．5W, voltage yagenwe ni DC 48v.
Iyo ukoresheje PoE switch ishigikira IEEE802.3af isanzwe, imbaraga zigikoresho gikoresha ntishobora kurenga 12.95W;kimwe, mugihe ukoresheje PoE ihinduranya ya IEEE802.3at, imbaraga zigikoresho gikoresha ntishobora kurenga 25.5W.
Mubisanzwe, PoE ihindura ishyigikira IEEE802.3af / kurwego rusanzwe icyarimwe, amashanyarazi arahinduka.Kurugero, niba ihujwe nigikoresho cya 5W, itanga 5W yingufu;niba ihujwe nigikoresho cya 20W, noneho itanga 20W yingufu.
PoE ihinduranya ni amashanyarazi ashyigikira amashanyarazi kumurongo.Ugereranije na sisitemu zisanzwe, ama terefone (nka AP, kamera ya digitale, nibindi) ntabwo akenera insinga kugirango itange amashanyarazi, kandi byizewe kumurongo wose.UwitekaGuhindura PoEntishobora gutanga gusa ihererekanyabubasha ryimikorere isanzwe, ariko kandi itanga imikorere yumuriro kurundi ruhande rwumuyoboro.
Igikoresho cya nyuma cya PoE gikenera umugozi umwe gusa, kibika umwanya kandi gishobora kwimurwa uko bishakiye (byoroshye kandi byoroshye), bizigama ibiciro.
Igihe cyose PoE ihinduranya ihujwe na UPS, irashobora gutanga ingufu kubikoresho byose byanyuma-POE bifitanye isano mugihe amashanyarazi azimye.Abakoresha barashobora guhita kandi bavanga ibikoresho byumwimerere nibikoresho bya PoE kumurongo, kandi ibyo bikoresho birashobora kubana ninsinga zisanzwe za Ethernet.
