Guhindura PoEbivuga icyerekezo gishobora gutanga imiyoboro y'amashanyarazi kumurongo wa kure ukoresheje amashanyarazi. Nibikoresho bisanzwe bitanga amashanyarazi muri sisitemu yo gutanga amashanyarazi. Ariko, niba switch idafite imikorere ya POE, birashoboka ko module yinyongera ya poe yamashanyarazi ishobora kongerwaho ingufu AP ikoresheje switch? Mubyukuri, birashoboka. Birashobora gusa gufatwa nko gukoresha metero 4578 zidafite akamaro za kabili y'urusobe mumashanyarazi 100M kugirango wohereze ingufu. Nukuvuga guhuza POE ikomatanya (izwi kandi nka POE itanga amashanyarazi) hagati ya switch na AP, ariko ikibanza giterwa nuko AP yawe ishyigikira kwakira amashanyarazi ya POE.

PoE ihindura amashanyarazi uburyo bumwe

Niba rero ufite igisenge cyubatswe na simsiz AP, benshi barabishyigikiye. Impera imwe numuyoboro wumuyoboro uva kumurongo wumuyoboro, kurundi ruhande ni umuyoboro wumuyoboro hamwe numuyoboro wa DC, wacometse kumuyoboro wa AP hamwe nicyambu. Nibyo. Ariko, muriki gihe, hari uburyo bubiri bwo gukoresha POE kugirango utange ingufu kuri AP, ariko hiyongereyeho 48V kugeza 12V POE itandukanya yongerewe kuri AP.

Ubu bwoko bwa POE butandukanya mubyukuri ni DC48V kugeza 12V. Impera imwe numuyoboro wumuyoboro uva kumurongo wumuyoboro kugirango ucomeke muri POE, kurundi ruhande ni umuyoboro wumuyoboro wumuyoboro hamwe numuyoboro wamashanyarazi wa DC, ucomeka kumurongo wumuyoboro wa AP hamwe nicyambu.

PoE ihindura amashanyarazi uburyo bubiri

Iyindi mpera ni umuyoboro wumuyoboro, winjijwe mumurongo wurukuta rugana kuri AP. Irasa nimwe muburyo bwa mbere. Niba imfashanyigisho itanditse kugirango ishyigikire POE, muri rusange ntabwo ishyigikiwe, kuko kongeraho iki gice cyumuzunguruko bisaba amafaranga icumi. Igiciro. Shira kumurongo wumuyoboro uva kuri switch na 12V power adapt muri AP yawe, ariko nta gice cya transformateur; ihuriro rya DATA rirashobora guhuzwa na AP. Niba ishyigikiwe, 48V POE itanga amashanyarazi irashobora guhuzwa hagati ya switch na AP. Hano hari ibyambu bibiri kuri module ya POE itanga amashanyarazi, kandi switch ihujwe na DATA yanditse. Icyambu cya DATA cyacometse kumurongo wumuyoboro uva kuri switch, hanyuma icyambu cya DATA & POWER cyacometse mumurongo wumuyoboro ugana kuri AP. Noneho umuyoboro wumuyoboro kumurongo wa AP uhujwe na POE itandukanya cyangwa itandukanya, nayo irashyigikirwa, ariko amashanyarazi arahagaze kandi uburebure bwumugozi wemerewe kugera kuri metero 100 cyangwa zirenga. Ubu buryo bufite igiciro gito, ariko niba ubwiza bwumugozi wurusobe ari bubi cyane cyangwa birebire cyane, bizatera amashanyarazi adahagije kuri AP.

Inama zo guhinduranya POE

Uburyo bwa mbere buhenze kandi busaba AP gushyigikira amashanyarazi ya Poe. Niba udashyigikiye, ntushobora gukoresha ubu buryo bwo guhuza. Bitabaye ibyo, nibyiza niba ifite ibikoresho byikora byerekana ibyuma byakira ingufu. Niba POE module ihatirwa gutanga ingufu, izatwika AP. Mubisanzwe, guhuza byoroshye kumasoko nimwe ifite impera imwe. Umuyoboro umwe numuyoboro umwe DC wumugore. Niba ishyigikiye imfashanyigisho izandikwa (cyangwa ubaze umucuruzi), kurugero, byanditswe ko ishyigikira IEEE 802.

Icyambu cya DC cyumugore kuri kombineri icomekwa mumashanyarazi ya AP, kandi irakwiriye gusa ibidukikije 100M. Niba ihujwe numuyoboro wa Gigabit, izatwika igikoresho. Ubu buryo ntabwo buri murwego rwa POE isanzwe. Niba udacometse kurukuta, ugomba kugura ubwo bwoko bwa modular combiner. Bamwe mubakora bazaba abanebwe bakandika gusa ko bashyigikiye amashanyarazi ya POE. 3af cyangwa IEEE 802.3at, bivuze ko bayishyigikiye.
