Nyob rau hauv niaj hnub no kev nce digital ntiaj teb, qhov xav tau kom muaj kev nrawm, txhim khu kev qha cov kev sib txuas hauv internet loj dua. Qhov no yog qhov tseeb tshwj xeeb rau cov lag luam thiab cov koomhaum, qhov chaw ruaj khov network txuas yog qhov tseem ceeb rau hnub-hnub ua haujlwm. Qhov no yog qhov chaw hluav taws xob dhau Ethernet (Poe) lub khawm hloov mus ua si.
Dab tsi yog aPoE HloovKoj nug? Lawv yog lub network hloov pauv uas muab cov khoom siv thiab cov ntaub ntawv sib kis rau Ethernet Cables rau cov khoom siv xws li IP cov koob yees duab, thiab wireless nkag tau cov ntsiab lus. Qhov kev tshem tawm qhov kev xav tau ntawm txoj hlua cais, ua kev teeb tsa thiab txij nkawm yooj yim.
Ib qho ntawm qhov zoo ntawm PE PE hloov pauv yog lub peev xwm rau cov khoom siv hluav taws xob ntau dua li ncua deb (txog 100 meters). Qhov no yog qhov tshwj xeeb tshaj yog siv rau sab nraum zoov lossis thaj chaw uas cov cheeb tsam hluav taws xob yuav tsis muaj. Ntxiv rau,PoE Hloovtuaj yeem ua qhov ua ntej thiab tswj lub zog faib kom ntseeg tau tias cov khoom siv tseem ceeb tau txais lub zog ua ntej.
Thaum xaiv ib tug poe hloov, muaj ob peb qhov tseem ceeb los xav txog. Ua ntej, lub zog peev nyiaj ntawm ib qho hloov yog qhov tseem ceeb vim tias nws qhia tau ntau npaum li cas lub zog hloov tuaj yeem muab rau cov khoom siv. Kuj tseem xav txog tus naj npawb ntawm PoE ports yuav tsum tau, nrog rau cov ntaub ntawv hloov pauv ntawm tus hloov pauv thiab tag nrho network kev ua haujlwm.
Lwm qhov kev txiav txim siab tseem ceeb yog qhov sib xws ntawm Poe hloov nrog cov cuab yeej nws lub zog. Nws yog qhov tseem ceeb los xyuas kom meej tias tus hloov yuav tuaj yeem muab lub zog tsim nyog rau txhua cov cuab yeej tsim nyog thiab txhawb nqa cov txheej txheem kev sib txuas ua ke.
Installation-paub qab hau, poe hloov tau yooj yim los teeb tsa. Lawv tuaj yeem yooj yim sib xyaw ua ke rau cov kev sib xyaw uas twb muaj lawm thiab muaj ntau qhov ntau thiab tsawg thiab kev teeb tsa kom tau raws li cov cai sib txawv. Feem ntau cov poe hloov mus los kuj tuaj nrog kev tswj software uas ua rau nws yooj yim saib xyuas thiab tswj cov khoom siv sib txuas.
Ntxiv nrog rau lawv cov kev coj ua, PEe Hloov kuj tuaj yeem txuag cov nqi thiab nce lub zog txuag hluav taws xob. Los ntawm kev siv ib qho cable rau fais fab thiab cov ntaub ntawv kis, cov lag luam tuaj yeem txo cov ntaub lag luam uas yuav tsum tau, yog li txo qis kev teeb tsa thiab kev kho tus nqi. Ib qho ntxiv, muaj peev xwm remotely rebotely li cov poe hloov txuag lub sijhawm thiab cov peev txheej.
Zuag qhia tag nrho, Poe hloov yog ib qho kev daws teeb meem thiab cov tshuaj muaj txiaj ntsig rau kev tswj hwm thiab tswj cov network sib txuas. Lawv lub peev xwm muab cov khoom siv hluav taws xob muaj zog thiab cov ntaub ntawv sib kis dhau ib qho eternet cable ua rau lawv zoo tshaj rau ntau yam kev siv los ntawm cov lag luam me rau cov lag luam me.
Hauv kev xaus,PoE HloovYog cov cuab yeej muaj txiaj ntsig zoo rau kev ua kom tau txais cov kev xav tau ntawm cov tes hauj lwm niaj hnub no. Lawv lub peev xwm los ua kom yooj yim txhim kho, txo cov nqi thiab muab cov zog hluav taws xob ua rau lawv mus rau ib lub koom haum nrhiav kom tau yooj yim. Txawm hais tias muaj lub koob yees duab IP, lossis cov ntsiab lus tsis sib haum, PEe hloov pauv yog kev xaiv ntawm kev xaiv, txhawj xeeb-kev sib txuas dawb.
