UwitekaGuhindura PoEni ahinduraishyigikira amashanyarazi kumurongo. Ugereranije nibisanzwehindura, ingufu zakira itumanaho (nka AP, kamera ya digitale, nibindi) ntikeneye kuba insinga kugirango itange amashanyarazi, kandi kwizerwa kwurusobe rwose ni hejuru.
Itandukaniro hagati ya PoE ihinduranya na swic zisanzwe
PoEhindurani bitandukanye na bisanzwehindura, PoEhindurantishobora gutanga gusa ibikorwa byo kohereza bisanzwehindura.hinduraunyuze kumurongo. Muri iki gihe, kamera ntabwo ikora. Niba kamera idahujwe no gutanga amashanyarazi, ariko insinga yayo yohereza imiyoboro ihujwe na PoEhindura, 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.
POEhinduraikoranabuhanga 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 PoEhinduraishyigikira igipimo cya IEEE802.3af, imbaraga z'igikoresho gikoreshwa ntishobora kurenga 12.95W; kimwe, mugihe ukoresheje PoEhinduraya IEEE802.3at bisanzwe, imbaraga zigikoresho gikoreshwa ntigishobora kurenga 25.5W.
Mubisanzwe, PoEhinduraishyigikira 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 ibikorwa byo kohereza bisanzwehindura, ariko kandi utange amashanyarazi kumurimo 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 PoEhinduraihujwe na UPS, irashobora gutanga ingufu kubikoresho byose byinyuma-POE bijyanye nibikoresho iyo amashanyarazi azimye. Abakoresha barashobora guhita kandi bavanga ibikoresho byumwimerere nibikoresho bya PoE kumurongo, kandi ibyo bikoresho birashobora kubana ninsinga zisanzwe za Ethernet.
