Nyob rau niaj hnub no lub ntiaj teb digital nce zuj zus, qhov xav tau rau kev sib txuas siab ceev, txhim khu kev qha hauv internet yog ntau dua li qhov qub. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov lag luam thiab cov koom haum, qhov twg kev sib txuas lus ruaj khov yog qhov tseem ceeb rau kev ua haujlwm txhua hnub. Qhov no yog qhov uas Power over Ethernet (PoE) keyboards tuaj rau hauv kev ua si.
Dab tsi yog aPoE hloovkoj nug? Lawv yog cov hloov pauv hauv lub network uas muab lub zog thiab cov ntaub ntawv xa mus hla Ethernet cables rau cov khoom siv xws li IP koob yees duab, VoIP xov tooj, thiab cov ntsiab lus nkag wireless. Qhov no tshem tawm qhov kev xav tau ntawm cov hlua hluav taws xob sib cais, ua rau kev teeb tsa thiab kev saib xyuas yooj yim dua.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm PoE keyboards yog lub peev xwm los siv cov khoom siv hluav taws xob ntev ntev (txog 100 meters). Qhov no yog qhov tshwj xeeb tshaj yog rau kev teeb tsa sab nraum zoov lossis thaj chaw uas cov hluav taws xob hluav taws xob yuav tsis tshua muaj. Ntxiv rau,PoE hloovtuaj yeem ua ntej thiab tswj hwm kev faib hluav taws xob kom ntseeg tau tias cov cuab yeej tseem ceeb tau txais lub zog ua ntej.
Thaum xaiv qhov hloov pauv PoE, muaj ntau yam tseem ceeb los xav txog. Ua ntej, cov peev nyiaj siv hluav taws xob ntawm qhov hloov pauv tseem ceeb vim nws qhia tias lub zog hloov pauv tuaj yeem muab tau rau cov khoom siv sib txuas. Kuj xav txog tus naj npawb ntawm PoE cov chaw nres nkoj xav tau, nrog rau cov ntaub ntawv hloov ceev ntawm kev hloov thiab kev ua haujlwm hauv network tag nrho.
Lwm qhov kev txiav txim siab tseem ceeb yog kev sib raug zoo ntawm PoE hloov nrog cov cuab yeej nws lub zog. Nws yog ib qho tseem ceeb kom ntseeg tau tias qhov hloov pauv tuaj yeem muab cov kev xav tau ntawm lub zog tsim nyog rau txhua yam khoom siv txuas nrog thiab txhawb nqa cov txheej txheem kev sib txuas uas xav tau.
Installation-wise, PoE keyboards kuj yooj yim rau teeb. Lawv tuaj yeem yooj yim ua ke rau hauv cov tes hauj lwm uas twb muaj lawm thiab tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab kev teeb tsa kom tau raws li qhov xav tau sib txawv. Feem ntau PoE keyboards kuj tuaj nrog kev tswj software uas ua rau nws yooj yim los saib xyuas thiab tswj cov khoom siv sib txuas.
Ntxiv nrog rau lawv qhov kev ua tau zoo, PoE keyboards kuj tseem tuaj yeem txuag nqi thiab ua kom lub zog ua haujlwm tau zoo. Los ntawm kev siv tib lub cable rau lub zog thiab cov ntaub ntawv xa mus, cov lag luam tuaj yeem txo qhov kev xaim hluav taws xob xav tau, yog li txo qis kev txhim kho thiab kho cov nqi. Tsis tas li ntawd, muaj peev xwm rov pib dua cov cuab yeej los ntawm kev hloov PoE txuag lub sijhawm thiab cov peev txheej.
Zuag qhia tag nrho, PoE hloov yog ib qho kev daws teeb meem ntau yam thiab muaj txiaj ntsig rau kev siv hluav taws xob thiab tswj cov khoom siv sib txuas. Lawv lub peev xwm los muab lub zog thiab cov ntaub ntawv xa mus dhau ib qho Ethernet cable ua rau lawv zoo tagnrho rau ntau yam kev siv los ntawm kev lag luam me mus rau cov lag luam loj.
Hauv kev xaus,PoE hloovyog cov cuab yeej tseem ceeb rau kev ua kom tau raws li cov kev xav tau ntawm cov network niaj hnub no. Lawv lub peev xwm los ua kom yooj yim rau kev teeb tsa, txo cov nqi thiab muab lub zog zoo thiab cov ntaub ntawv hloov pauv ua rau lawv yuav tsum muaj rau txhua lub koom haum tab tom nrhiav kom yooj yim rau lawv lub network infrastructure. Txawm hais tias lub hwj chim IP lub koob yees duab, VoIP xov tooj, lossis cov ntsiab lus nkag mus rau wireless, PoE keyboards yog cov kev xaiv rau kev txhim khu kev qha, tsis muaj kev txhawj xeeb.
