PoE injector ua haujlwm li cas?

Thaum cov keyboards lossis lwm yam khoom siv uas tsis muaj lub zog siv hluav taws xob txuas nrog cov cuab yeej siv hluav taws xob (xws li IP koob yees duab, wireless APs, thiab lwm yam), PoE fais fab mov tuaj yeem muab kev txhawb nqa hluav taws xob thiab cov ntaub ntawv xa mus rau cov khoom siv hluav taws xob tib lub sijhawm, nrog kev sib kis. nyob deb li 100 Meter.Feem ntau hais lus, PoE fais fab mov thawj zaug hloov AC lub zog rau DC lub zog, thiab tom qab ntawd muab lub zog rau cov khoom siv hluav taws xob tsawg PoE.

Yuav siv PoE injector li cas?

Hauv seem no, peb tsuas yog siv PoE-enabled IP koob yees duab (los yog lwm yam PoE cov khoom siv davhlau ya nyob twg) ua piv txwv los piav qhia yuav ua li cas siv PoE fais fab injectors thiab tsis-PoE keyboards los muab lub zog.Cov cuab yeej yuav tsum tau npaj yog: ob peb lub koob yees duab IP, ob peb PoE cov khoom siv hluav taws xob (tus lej yuav tsum tau txiav txim siab raws li tus naj npawb ntawm IP koob yees duab), tus qauv tsis-PoE hloov thiab ntau lub network cables (Cat5eCat6Cat6a).
1. Ntsuas tag nrho cov cuab yeej ua ntej kom ntseeg tau tias lub koob yees duab IP, PoE fais fab mov thiab lub koob yees duab tswj kev ua haujlwm txhua zaus.Ua ntej txhim kho lub koob yees duab, ua kom tiav lub network configuration ntsig txog lub koob yees duab ua ntej.
2. Tom qab ua tiav thawj kauj ruam, siv lub network cable txuas lub koob yees duab mus rau qhov chaw nres nkoj hluav taws xob ntawm PoE fais fab mov.
3. Tom ntej no, nruab lub koob yees duab rau hauv qhov chaw uas muaj teeb pom kev zoo kom pom cov duab uas lub koob yees duab tau pom meej dua.
4. Siv lwm lub network cable los txuas cov ntaub ntawv kis tau tus mob chaw nres nkoj ntawm tus tes hloov thiab lub hwj huam mov.
5. Thaum kawg, ntsaws lub hwj chim qaum ntawm lub hwj huam mov rau hauv lub qhov hluav taws xob AC ze tshaj plaws.

Yam dab tsi yuav tsum tau xav txog thaum yuav khoom PoE Injector?

* Tus naj npawb ntawm cov khoom siv hluav taws xob: Yog tias tsuas muaj ib qho khoom siv hluav taws xob, ib qho chaw nres nkoj PoE fais fab mov txaus.Yog tias muaj ntau yam khoom siv PoE davhlau ya nyob twg, koj yuav tsum xyuas kom meej tias tus naj npawb ntawm PoE fais fab injector ports sib tw.
* PoE ib qho chaw nres nkoj fais fab mov loj: Nws yog ib qho tsim nyog los xyuas kom meej tias cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob sib txuas ua tau raws li tus qauv PoE.Feem ntau muaj peb tus qauv PoE fais fab mov: 802.3af (PoE), 802.3at (PoE+), thiab 802.3bt (PoE++).Lawv cov khoom siv hluav taws xob siab tshaj plaws yog 15.4W, 30W, thiab 60W / 100W feem.
* Fais fab mov voltage: xyuas kom meej tias qhov kev khiav hauj lwm voltage ntawm lub hwj huam mov thiab cov khoom siv hluav taws xob sib txuas tau zoo ib yam.Piv txwv li, feem ntau cov koob yees duab soj ntsuam ua haujlwm ntawm 12V lossis 24V.Lub sijhawm no, koj yuav tsum tau ua tib zoo saib xyuas kom ntseeg tau tias lub zog hluav taws xob voltage tus nqi ntawm PoE lub zog hluav taws xob sib tw ua haujlwm voltage tus nqi ntawm lub koob yees duab kom tsis txhob muaj hluav taws xob ntau dhau lossis ua haujlwm tsis ua haujlwm.

FAQ ntawm PoE Injector:

Q: Puas yog PoE fais fab mov muab lub zog rau lub gigabit hloov?
A: Tsis yog, tshwj tsis yog lub gigabit hloov pauv muaj PoE fais fab chaw nres nkoj.

Q: Puas yog PoE fais fab mov muaj qhov chaw nres nkoj tswj?
A: Tsis yog, PoE fais fab mov tuaj yeem muab hluav taws xob ncaj qha rau PoE cov khoom siv hluav taws xob los ntawm cov khoom siv hluav taws xob, ntsaws thiab ua si.Tsis tas li ntawd, nws tseem muaj lub luag haujlwm tiv thaiv luv luv, uas tuaj yeem muab ncaj qha tam sim no rau cov khoom siv wireless thiab cov cuab yeej saib xyuas.Yog tias koj xav tau cov khoom siv hluav taws xob PoE nrog kev tswj hwm, koj tuaj yeem xaiv qhov hloov pauv PoE.
