Cov keyboards feem ntau siv rau hauv cov haujlwm tam sim no tsis muaj zog, tshwj xeeb tshaj yogPOE hloov.POE tseem hu ua lub zog hauv cheeb tsam network-raws li lub zog siv hluav taws xob (POL, Fais fab hla LAN) lossis Active Ethernet (Active Ethernet), qee zaum hu ua Power over Ethernet.Qhov no yog tus qauv tshiab tshaj plaws rau ib txhij xa cov ntaub ntawv thiab lub zog hluav taws xob siv cov qauv Ethernet kis tau tus mob uas twb muaj lawm, thiab tswj kev sib raug zoo nrog Ethernet systems thiab cov neeg siv tam sim no.Yog li, peb xaiv POE hloov pauv li cas?

1. Xav txog lub zog ntawm koj cov khoom siv

Ua ke xaiv lub PoE hloov nrog lub zog siab.Yog tias lub zog ntawm koj cov khoom siv qis dua 15W, ces xaiv qhov hloov pauv PoE uas txhawb nqa tus qauv 802.3af.Yog tias lub zog loj dua 15W, xaiv qhov hloov hluav taws xob siab nrog 802.3at tus qauv.Tam sim no, ntau PoE keyboards txhawb ob qho tib si af thiab ntawm, yog li them nyiaj ntau dua thaum yuav khoom.

2. Lub cev chaw nres nkoj

Ua ntej tshaj plaws, nws yog ib qho tsim nyog los txiav txim siab tus naj npawb ntawm kev hloov pauv, tus naj npawb ntawm cov chaw nres nkoj fiber ntau, kev tswj xyuas network, ceev (10/100/1000M) thiab lwm yam teeb meem.Tam sim no, cov interfaces ntawm kev ua lag luam feem ntau yog 8, 12, 16, thiab 24 chaw nres nkoj.Feem ntau muaj ib lossis ob qhov chaw kho qhov muag fiber ntau, thiab koj yuav tsum tau them sai sai rau seb qhov chaw nres nkoj kho qhov muag yog 100M lossis 1000M.Nws nyob ntawm qhov xwm txheej.

PoE keyboards feem ntau yog siv los txuas cov khoom siv hluav taws xob thiab siv los ua cov keyboards nkag.Xav txog tus naj npawb ntawm PoE fais fab mov chaw nres nkoj txhawb nqa los ntawm kev hloov pauv raws li tus naj npawb ntawm cov khoom siv fais fab.Tsis tas li ntawd, nws tseem yuav tsum tau xav txog qhov siab tshaj plaws uas qhov chaw nres nkoj yuav tsum tau txhawb nqa raws li lub zog siv hluav taws xob thiab cov kev xav tau tiag tiag.Piv txwv li, yog tias qhov chaw nres nkoj ntawm AP yog Gigabit thiab siv 11AC lossis dual-band, Gigabit nkag tuaj yeem txiav txim siab.

3. Fais fab mov tsis

Xaiv qhov kev hloov tsim nyog raws li cov txheej txheem muab hluav taws xob (xws li 802.3af, 802.3at lossis tsis yog tus qauv PoE) txhawb nqa los ntawm lub davhlau ya nyob twg (AP lossis IP lub koob yees duab).PoE fais fab mov raws tu qauv txhawb nqa los ntawm kev hloov pauv yuav tsum ua raws li lub zog siv hluav taws xob.Muaj ntau yam kev nyab xeeb muaj peev xwm nyob rau hauv tsis yog tus qauv PoE keyboards.Nws raug nquahu kom koj sim xaiv tus qauv 48V PoE hloov khoom siv.

4. Cov txheej txheem xaim

Cov neeg siv tuaj yeem sib piv thiab xam cov nqi ntawm lub davhlau ya nyob twg lub chaw xa hluav taws xob hauv zos thiab tus nqi ntawm kev siv PoE hloov rau lub hwj chim.Tam sim no, lub hwj huam mov nrug ntawm PoE keyboards yog nyob rau hauv 100 meters.Tsis muaj kev txwv layout, uas tuaj yeem txuag tau li 50% ntawm tus nqi tag nrho.Kev xaim hauv 100 meters tuaj yeem hloov kho lub network yam tsis muaj kev txwv los ntawm kev teeb tsa ntawm cov kab hluav taws xob.Dai wireless APs, lub koob yees duab network thiab lwm yam khoom siv davhlau ya nyob twg ntawm cov phab ntsa siab lossis qab nthab rau kev nthuav dav, yooj yim txuas, thiab zoo nkauj zoo nkauj.

5. Kev muag khoom ua ntej thiab kev pab cuam tom qab muag

Xaiv cov tub lag luam txhim khu kev qha kom tau txais kev tshaj lij ua ntej muag thiab kev pab cuam tom qab muag
