PoE hloov yog dab tsi?
PoE hloov (piv txwv li, Fais fab tuag hla Ethernet hloov) yog lub pob hluav taws xob txuas uas siv lub zog dua Ethernet technology. Nws tuaj yeem ua tiav cov kev sib txuas xov tooj kom zoo thiab lub zog xa hluav taws xob los ntawm cov kab hluav taws xob, thiab muab cov ntaub ntawv teeb liab rau IP xov tooj, IP koob yees duab, txuas wireless txuas ntxiv thiab lwm yam khoom siv thiab ncaj qha tam sim no. Tam sim no muaj ntau hom PoE hloov ntawm khw, uas tuaj yeem muab faib ua 8-chaw nres nkoj / 16-chaw nres nkoj / 24-chaw nres nkoj PoE hloov raws li tus naj npawb ntawm cov chaw nres nkoj. Raws li seb lub pob hluav taws xob puas tuaj nrog lub microprocessor, nws tau muab faib ua tus tswj PoE hloov thiab tus tswj tsis tau PoE hloov.
PoE siv qhov twg?
Txhawm rau kom nkag siab qhov twg PoE hloov siv feem ntau, koj yuav tsum xub to taub qhov tsis hloov PoE hloov thiab qhov sib txawv ntawm PoE keyboards thiab non-PoE keyboards.
Non-PoE keyboards xa mus rau cov keyboards uas tsis muaj lub zog dua Ethernet muaj nuj nqi. Yog li no, cov kab hluav taws xob no tsis tuaj yeem muab lub zog rau PoE siv hluav taws xob los ntawm cov xov tooj network, tab sis tsuas tuaj yeem xa cov ntaub ntawv rau lawv.
Yog tias koj xav muab DC lub zog rau PoE uas siv cov cuab yeej, koj tuaj yeem siv cov khoom siv fais fab fais fab (PSE) xws li PoE fais fab siv fais fab (cov tshuab txuas hluav taws xob) nruab nrab ntawm cov hluav taws xob uas tsis yog PoE thiab PoE uas siv tau. Cov cuab yeej hluav taws xob no muaj peev xwm sib txuas tau cov ntaub ntawv ntawm cov tsis-PoE hloov nrog nws tus kheej lub zog hluav taws xob ua ke los muab DC lub zog thaum muab cov ntaub ntawv teeb liab rau PoE siv hluav taws xob. Txawm li cas los xij, vim tias cov khoom siv hluav taws xob (PSE) nws tus kheej tseem xav tau lub zog txuas hluav taws xob los muab lub zog (qee zaus nws yuav tsum ntxiv lub qhov txuas cais), yog li ntawd, cov xov tooj ntawm cov xov tooj thiab cov hlua yuav tsum muaj rau daim ntawv thov kev pabcuam nce ntxiv, ua rau muaj kev nce ntxiv hauv kev tsim kho thiab tus nqi, thiab tib lub sijhawm, rau kev tswj hwm thiab txij nkawm Ua rau muaj kev tsis yooj yim.
Piv nrog cov ntsuas hluav taws xob uas tsis yog PoE, PoE keyboards txuas tau yooj yim rau kev txuas. Nws tsuas xav tau tib lub network cable kom tau raws li ob qho tib si cov ntaub ntawv xa mus thiab DC lub zog hluav taws xob (ib kawg ntawm lub network cable txuas nrog lub cuab yeej tau txais kawg, thiab lwm qhov kawg txuas nrog RJ45 chaw nres nkoj ntawm PoE hloov), Nws txuag tau zoo kev siv cov khoom siv hluav taws xob yooj yim xws li cov hlua txuas hluav taws xob thiab lub zog siv hluav taws xob, ua kom yooj yim cov phiaj xwm xaib sib txuas, ua rau kev tsim vaj tsev yooj yim dua, thiab tswj thiab tswj kom yooj yim dua.
Hauv txoj kev xaus, piv rau cov tsis hloov PoE, PoE hloov hluav taws xob tuaj yeem muab cov neeg siv khoom muaj qhov hloov pauv yooj yim dua, yooj yim, thiab tus nqi ntau dua.
Yooj Yim: Tsis muaj cov khoom siv fais fab txuas ntxiv thiab txuas hluav taws xob txuas ntxiv, uas yooj yim kev xaib network, txuag chaw, thiab coj tau zoo rau kev xa xov hluav taws xob. Cov neeg siv tuaj yeem npaj lub xov tooj IP, IP koob yees duab thiab lwm yam khoom siv hluav taws xob tau txais raws li cov ntawv thov tiag tiag Qhov chaw teeb tsa. Ntxiv rau, PoE hloov chaw tuaj yeem ua ke nrog cov thev naus laus zis wireless kom ua tiav wireless cheeb tsam thaj chaw hauv nroog, nqa kev hloov pauv ntau dua.
Kev Yooj Yim: Tus PoE hloov txhawb nqa cov kis ntawm cov ntaub ntawv cov cim thiab ncaj qha tam sim no los ntawm lub network cable. Nws yog ib qho yooj yim rau kev txhim kho thiab tuaj yeem hloov mus ntawm qhov yuav. Ib qho ntxiv, PoE hloov tuaj yeem saib xyuas thiab tswj tau lub cuab yeej los ntawm Kev Tswj Network yooj yim (SNMP).
Raug nqi-qhov tseeb: qhov tseeb, ntau lub zog siv hluav taws xob (xws li cov koob yees duab keb soj ntsuam yees duab, thiab lwm yam) yuav tsum tau nruab rau hauv qhov chaw uas nws tsis yooj yim siv AC fais fab, thiab kev siv PoE keyboards tshem tawm qhov kev xav tau rau cov neeg siv yuav khoom cov khoom siv fais fab kim, lwm yam kab hlau, thiab cov thom khwm. Txuag lub sijhawm teeb tsa thiab nqi them rau ntau yam.
FAQ ：
1. Ib qho PoE puas tuaj yeem txuas tau rau lwm tus PoE hloov?
tuaj yeem. Kev hloov pauv ntawm PoE yuav tsuas yog muab cov ntaub ntawv sib kis thiab ncaj qha tam sim no mus rau lub zog tau txais cov cuab yeej (PD) thaum nws siv los ua lub zog hluav taws xob (PSE) kom paub txog lub zog txais hluav taws xob (PD). Ob txoj hlua PoE yog ob qho khoom siv hluav taws xob kawg. Yog tias lawv txuas nrog, lawv tuaj yeem siv ncaj qha raws li cov keyboards niaj hnub. Lub sijhawm no, ob tus PoE hloov tsuas ua cov ntaub ntawv sib kis thiab yuav tsis muab hwj chim rau ib leeg.
2. Dab tsi yog qhov sib txawv ntawm PoE hloov thiab PoE + hloov?
Qhov sib txawv ntawm PoE hloov thiab PoE + hloov chaw feem ntau yog qhov lawv muab DC lub zog sib txawv rau qhov tau txais cov khoom siv kawg.
3. Dab tsi yog qhov sib txawv ntawm tswj PoE hloov thiab lub pob tswj ntawm PoE uas tsis muaj kev tswj hwm?
Tus tswj tus tes hloov hluav taws xob PoE yog lub zog hloov dua Ethernet hloov uas txhawb nqa VLAN, SNMP, chaw nres nkoj iav, thiab lwm yam haujlwm. Nws tuaj yeem pab cov neeg siv faib thaj chaw rau kev siv sib txawv thiab ua tau zoo tswj thiab tswj hwm lub network. Txawm li cas los xij, vim hais tias cov PoE uas tsis tau tswj hwm tau hloov kho lub teeb tsa ua ntej, nws tuaj yeem tsuas yog kev sib txuas lus ntawm cov khoom siv, thiab tsis ua ntaub ntawv, thiab nws tsis tuaj yeem hloov pauv ntawm lub teeb tsa.
4.Cov lub koos pij tawj lossis lwm yam khoom siv tsis yog PoE txuas nrog PoE hloov? Yog tias nws txuas nrog, nws puas yuav raug puas ntsoog?
Yog tias koj xav txuas mus rau lwm cov khoom siv, koj yuav tsum xaiv tus qauv PoE hloov chaw hloov chaw tsis txhob siv PoE hloov. Qhov no vim tias tsuas yog tus lej pauv raws li PoE hloov ua haujlwm tau tshawb pom, nws tuaj yeem nrhiav cov cuab yeej ua haujlwm uas txhawb nqa lub Hwj Chim dhau Ethernet txuj ci thiab muab lub zog rau lawv. Yog tias nws pom tias cov cuab yeej txuas tsis ua raws li lub hwj chim dhau Ethernet tus qauv (ntawd yog, nws tsis muaj PoE ua haujlwm), nws yuav ua cov ntaub ntawv sib kis zoo li lub pob hloov mus, thiab yuav tsis muab lub hwj chim rau nws.
Txawm li cas los xij, cov kev hloov pauv rau Po-tsis-tus qauv yog qhov txawv. Txawm hais tias cov khoom siv sib txuas puas ua raws li Lub Hwj Chim dhau Ethernet tus qauv (txawm nws txhawb nqa lub PoE ua haujlwm), nws yuav muab qee qhov nqi ntawm cov khoom siv ncaj qha rau nws. Yog tias cov cuab yeej txuas tsis yog cuab yeej PoE, nws yuav ua rau muaj kev puas tsuaj.
Raws li qhov PoE hloov khoom ntawm lub khw muag khoom muaj kev txhawj xeeb, lawv yog tus qauv raws li PoE hloov. Txawm li cas los xij, tseem muaj qee tus neeg muab khoom siv uas muab cov khoom txheem uas tsis yog PoE hloov. Xav txog kev nyab xeeb thiab cov ua tau, nws muaj kev nyab xeeb dua yog xaiv cov qauv PoE hloov raws.
