Qhov loj ntawm cov cuab yeej siv los ntawm cov ntawv thov kev lag luam xws li kev thauj mus los, cov chaw pej xeem thiab kev tsim khoom siv hluav taws xob yuav ua rau cov cables nyob rau hauv qhov xwm txheej tsis zoo. Nrog rau kev lag luam cov cuab yeej ua kom muaj zog-dhuav, PoE thev naus laus zis yeej lub koob npe nrov ntawm cov neeg siv nrog lub peev xwm los muab lub zog ntau dua thiab txo cov xov tooj ntawm cov cables xav tau. Hauv tsab xov xwm no peb yuav tham txog dab tsi yog qhov hloov pauv PoE thiab siv PoE hloov li cas.

PoE Hloov yog dab tsi?

PoE hloov lossis lub zog dhau Ethernet hloov pauv yog lub network hloov uas siv fais fab dhau Ethernet thev naus laus zis. Nrog rau PoE network hloov, kev sib txuas hauv network thiab lub zog los khiav PD (lub zog siv hluav taws xob) tuaj yeem pom tau zoo dua ntawm Ethernet cable. PoE network hloov tau muab faib ua ntau hom, xws li 8/12/24/48 chaw nres nkoj PoE hloov, lossis tsis tswj thiab tswj PoE hloov.

Vim li cas koj thiaj xav tau PoE Hloov?
Raws li kev ua haujlwm ntawm PoE vs. tsis yog-PoE hloov, PoE hloov coj tau txiaj ntsig los ntawm cov hauv qab no:
Flexibility:Tau tshem ntawm cov kev txwv ntawm cov tsis-PoE keyboards xav tau ntxiv PSEs thiab txuas ntxiv cables, PoE keyboards tau txais txiaj ntsig zoo rau cov neeg siv cov kab hluav taws xob network. Nws tso cai rau PDs zoo li IP soj ntsuam lub koob yees duab kom raug teeb tsa raws li qhov nws xav tau mus. Tsis tas li ntawd, kev sib txuas ntawm PoE hloov thiab wireless thev naus laus zis tuaj yeem ua rau qhov chaw tsis muaj kab hluav taws xob ua tau.
Simplicity:Tsis tas yuav xav txog PSEs ntxiv thiab qhov chaw teeb tsa zoo li qhov tsis yog-PoE hloov, PoE hloov pauv yooj yim rau tag nrho kev xa tawm network. Tsis tas li ntawd, cov keyboards PoE zoo kuj tseem ua kom yooj yim network tswj raws tu qauv (SNMP), uas muab txoj hauv kev yooj yim rau kev saib xyuas thiab tswj kev hloov.
Nqi-Efficient:Nrog PoE network hloov, tsis tas yuav tsum muaj rau cov neeg siv los yuav thiab teeb tsa cov xov hluav taws xob ntxiv thiab qhov hluav taws xob, uas tsim kev txuag nyiaj tseem ceeb ntawm kev teeb tsa thiab tu cov nqi thiab sijhawm.
