Guhindura PoE ni switch ishigikira amashanyarazi kumurongo. Ugereranije na sisitemu zisanzwe, amashanyarazi yakira itumanaho (nka AP, kamera ya digitale, nibindi) ntabwo akenera insinga kugirango itange amashanyarazi, yizewe cyane kumurongo wose.Uyu munsi,Ikoranabuhanga rya JHAAzamenyekanisha ikoranabuhanga nibyiza bya POE byahinduwe muburyo burambuye hano.

Itandukaniro hagati ya PoE ihinduranya na basanzwe

Ihinduka rya PoE ntirishobora gutanga gusa uburyo bwo kohereza ibintu bisanzwe, ariko kandi ritanga imikorere yumuriro kurundi ruhande rwumugozi. Kurugero, hariho kamera yo kugenzura ibyuma bya digitale (bisaba gutanga amashanyarazi kugirango ikore bisanzwe), ariko ntabwo ihujwe nisoko ryingufu, ariko ihujwe na enterineti 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 igikoresho cyumuyoboro uhujwe gifite PoE power yakira iherezo. Niba ihari, izahabwa ingufu, niba atariyo, ntabwo izahabwa ingufu kandi itanga gusa ihererekanyamakuru. Niba atari bisanzwe, izatanga ingufu muburyo butaziguye. Niba iyi link itamenyekanye, ibikoresho birashobora gutwikwa.

POE hindura ikoranabuhanga nibyiza

Hariho amahame abiri yingenzi yo guhinduranya PoE kumasoko, IEEE802.3af na 802.3 kuri, ibyo bikaba bisobanura ingufu zitanga amashanyarazi ya 15.4W na 30W, ariko kubera igihombo mugikorwa cyo kohereza, amashanyarazi nyirizina ni 12.95W na 25.5W, igipimo cya voltage Ni DC 48v. Iyo ukoresheje PoE switch ishigikira IEEE802.3af isanzwe, imbaraga zicyuma gikoresha ingufu ntizishobora 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, itanga 20W yingufu.A PoE switch ni switch ishigikira amashanyarazi kumurongo. Ugereranije na sisitemu zisanzwe, ama terefone (nka AP, kamera ya digitale, nibindi) ntabwo akenera insinga kugirango itange amashanyarazi, yizewe cyane kumurongo wose. Ihinduka rya PoE ntirishobora gusa gutanga imikorere yo kohereza ibintu bisanzwe, ariko kandi ritanga imikorere yumuriro kurundi ruhande rwumugozi. Igikoresho cya nyuma cya PoE gikenera umugozi umwe gusa, kibika umwanya, gishobora kwimurwa uko bishakiye (byoroshye kandi byoroshye), kandi 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.
