Nrog rau qhov muaj koob meej ntawm IP xov tooj, kev saib xyuas video network thiab cov khoom siv wireless Ethernet hauv lub network, qhov yuav tsum tau muab kev txhawb zog los ntawm Ethernet nws tus kheej tau dhau los ua nrawm dua.Feem ntau, cov khoom siv davhlau ya nyob twg xav tau DC fais fab mov, thiab cov khoom siv davhlau ya nyob twg feem ntau yog ntsia rau hauv qab nthab lossis sab nraum zoov siab ntawm hauv av.Nws yog qhov nyuaj kom muaj lub qhov hluav taws xob tsim nyog nyob ze.Txawm hais tias muaj lub qhov (socket), AC / DC converter xav tau los ntawm cov khoom siv davhlau ya nyob twg yog qhov nyuaj rau muab tso rau.Tsis tas li ntawd, hauv ntau daim ntawv thov LAN loj, cov thawj coj yuav tsum tswj hwm ntau lub davhlau ya nyob twg tib lub sijhawm.Cov khoom siv no xav tau kev sib koom ua ke ntawm kev siv hluav taws xob thiab kev tswj hwm kev sib koom ua ke.Vim qhov kev txwv ntawm qhov chaw siv hluav taws xob, nws ua rau muaj kev cuam tshuam loj rau kev tswj fais fab.Ethernet fais fab mov Poe tsuas yog daws qhov teeb meem no.

Poe yog ib lub tshuab hluav taws xob xaim Ethernet.Lub network cable siv rau kev xa cov ntaub ntawv muaj peev xwm ntawm DC fais fab mov tib lub sijhawm, uas tuaj yeem daws cov teeb meem hauv nruab nrab ntawm cov khoom siv hluav taws xob xws li IP xov tooj, wireless AP, portable device charger, daim npav nyeem ntawv, lub koob yees duab thiab cov ntaub ntawv tau txais.Poe fais fab mov muaj qhov zoo ntawm kev ntseeg siab, kev sib txuas yooj yim thiab cov qauv sib koom ua ke:

Kev ntseeg tau: Poe ntaus ntawv tuaj yeem muab lub zog rau ntau lub davhlau ya nyob twg tib lub sijhawm, kom paub txog lub zog nruab nrab ntawm lub zog thiab lub zog thaub qab tib lub sijhawm.Kev sib txuas yooj yim: cov khoom siv davhlau ya nyob twg tsis xav tau cov khoom siv hluav taws xob sab nraud, tab sis tsuas yog ib lub network cable xwb.Txheem: ua raws li cov qauv thoob ntiaj teb thiab siv lub ntiaj teb sib koom ua ke RJ45 lub zog sib txuas kom ntseeg tau tias muaj kev sib txuas nrog cov khoom siv los ntawm cov tuam txhab sib txawv.
