PoE hloovyog hais txog kev hloov pauv uas tuaj yeem muab lub zog hluav taws xob rau cov chaw taws teeb tswj hluav taws xob los ntawm lub network cable. Nws yog ib qho khoom siv hluav taws xob zoo sib xws hauv PoE lub tshuab hluav taws xob. Txawm li cas los xij, yog tias qhov hloov pauv tsis muaj POE muaj nuj nqi, puas tuaj yeem ntxiv poe fais fab mov module ntxiv rau lub zog AP los ntawm kev hloov? Qhov tseeb, nws ua tau. Nws tsuas tuaj yeem suav tau tias yog siv lub idle 4578 ko taw ntawm lub network cable hauv 100M network ib puag ncig kom xa hluav taws xob. Qhov ntawd yog txhawm rau txuas POE cov khoom sib txuas (tseem hu ua POE lub zog hluav taws xob) ntawm qhov hloov pauv thiab AP, tab sis qhov chaw nyob ntawm seb koj AP puas txhawb tau POE fais fab mov.

Yog li yog tias koj muaj lub qab nthab-mounted wireless AP, feem ntau ntawm lawv txhawb nws. Ib kawg yog lub network cable los ntawm lub network chaw nres nkoj, thiab lwm qhov kawg yog lub network cable thiab DC plug, uas yog ntsaws rau hauv AP lub network chaw nres nkoj thiab lub hwj chim chaw nres nkoj. Qhov ntawd yog nws. Txawm li cas los xij, hauv qhov no, muaj ob txoj hauv kev siv POE los muab lub zog rau AP, tab sis ntxiv 48V rau 12V POE splitter ntxiv rau AP.

Hom POE splitter no yeej yog DC48V rau 12V transformer. Ib kawg yog lub network cable los ntawm lub network chaw nres nkoj mus ntsaws rau hauv POE, thiab lwm qhov kawg yog lub network cable taub hau thiab DC fais fab plug, uas yog ntsaws rau hauv AP lub network chaw nres nkoj thiab lub hwj chim chaw nres nkoj.

Lwm qhov kawg yog lub network cable ntsaws, uas tau muab tso rau hauv lub network phab ntsa ntsaws ua rau AP. Nws zoo ib yam li ib qho hauv thawj txoj kev. Yog tias phau ntawv tsis sau los txhawb POE, feem ntau nws tsis txaus siab, vim hais tias ntxiv ib feem ntawm lub Circuit Court yuav tsum tau kaum tawm yuan. Nqi. Txuas lub network cable los ntawm kev hloov thiab 12V fais fab adapter hauv koj lub AP, tab sis tsis muaj qhov hloov pauv; qhov kev sib txuas DATA tuaj yeem txuas nrog AP. Yog tias nws tau txais kev txhawb nqa, 48V POE fais fab mov module tuaj yeem txuas ntawm qhov hloov pauv thiab AP. Muaj ob lub network chaw nres nkoj ntawm POE fais fab mov module, thiab qhov hloov pauv txuas nrog DATA tau sau. DATA chaw nres nkoj yog ntsaws rau hauv lub network cable los ntawm kev hloov, thiab DATA & POWER chaw nres nkoj yog ntsaws rau hauv lub network cable coj mus rau AP. Tom qab ntawd lub network cable ntawm AP kawg yog txuas nrog POE splitter lossis splitter, uas kuj tau txais kev txhawb nqa, tab sis cov khoom siv hluav taws xob ruaj khov thiab qhov ntev ntawm lub network cable raug tso cai mus txog 100 meters lossis ntau dua. Txoj kev no muaj tus nqi qis tshaj, tab sis yog tias qhov zoo ntawm lub network cable tsis zoo lossis ntev dhau lawm, nws yuav ua rau lub zog tsis txaus rau AP.

Cov lus qhia rau POE keyboards

Thawj txoj kev yog tus nqi thiab xav tau AP los txhawb Poe fais fab mov. Yog tias koj tsis txhawb nws, koj siv tsis tau txoj kev txuas no. Txwv tsis pub, nws yog qhov zoo yog tias nws tau nruab nrog tsis siv neeg tshawb pom lub zog txais khoom siv. Yog tias POE module raug yuam kom muab lub zog, nws yuav hlawv AP. Feem ntau, cov khoom sib txuas yooj yim tshaj plaws ntawm kev ua lag luam yog ib qho kawg. Ib qhov chaw nres nkoj network thiab ib lub DC poj niam connector. Txawm hais tias nws txhawb nqa phau ntawv yuav raug sau (lossis nug tus tub lag luam), piv txwv li, nws tau sau tias nws txhawb IEEE 802.

DC poj niam qhov chaw nres nkoj ntawm cov khoom sib txuas yog ntsaws rau hauv lub hwj chim adapter ntawm AP, thiab nws tsuas yog haum rau 100M network ib puag ncig. Yog tias nws txuas nrog hauv Gigabit network, nws yuav hlawv lub cuab yeej. Cov txheej txheem no tsis yog nyob rau ntawm cov qauv POE. Yog tias koj tsis ntsaws nws los ntawm phab ntsa, koj yuav tsum tau yuav hom modular combiner. Qee cov tuam txhab lag luam yuav tub nkeeg thiab tsuas yog sau tias lawv txhawb POE fais fab mov. 3af lossis IEEE 802.3at, uas txhais tau tias lawv txhawb nqa.
