4 Chaw nres nkoj Poe Vaj Huam Sib Luag Injector

Qhov no tsis yog - tus qauv passive PoE injector yog tsim los muab lub zog hla Ethernet cables rau cov khoom siv sib xws, txhawb nqa 4-chaw nres nkoj thiab 8-chaw nres nkoj teeb tsa. Nws siv 48V fais fab adapter kom tso tawm 48V lub zog sib npaug thoob plaws txhua qhov chaw nres nkoj, nrog lub zog sib npaug. Lub tsev no muaj cov ntaub ntawv yas ruaj khov, LED lub zog taw qhia kom yooj yim saib xyuas cov xwm txheej, thiab kev sib raug zoo nrog txhua qhov hloov Ethernet lossis router. Nws yog qhov zoo tshaj plaws rau kev siv lub xov tooj VoIP, IP koob yees duab, WiFi nkag tau cov ntsiab lus, thiab cov cuab yeej zoo sib xws. Tseem ceeb: Raws li ib tug passive injector, nws muab lub hwj chim tam sim ntawd raws li kev twb kev txuas yam tsis muaj nws pib-nrhiav, yog li xyuas kom meej tias koj cov cuab yeej txhawb tus pin configuration (4/5 zoo, 7/8 tsis zoo) kom tsis txhob muaj teeb meem.

Qhov no injector boasts ob peb yam tseem ceeb uas ua rau nws ib tug txhim khu kev qha kev xaiv rau network powering xav tau kev pab. Nws xa tib qhov hluav taws xob mus rau txhua qhov chaw nres nkoj, kom ntseeg tau tias txawm tias lub zog faib tsis muaj kev nyiam. Tus qauv tsim tsis zoo txhais tau hais tias nws yuam cov khoom siv hluav taws xob sai li sai tau thaum cov khoom siv txuas nrog, uas yog qhov zoo rau cov khoom siv tsis yog -PoE thaum ua ke nrog PoE splitter. Nws ua haujlwm seamlessly nrog cov khoom siv network txheem, ua raws li ncaj nraim -los ntawm 568B cabling rau hassle- kev sib txuas dawb. Cov chaw nres nkoj PoE txuas rau choj AP lossis CPE ntaus ntawv WAN interfaces, thaum LAN cov chaw nres nkoj txuas ncaj qha rau routers, keyboards, lossis host computers. Ntxiv rau, lub davhlau ya nyob twg ntsuab txuas mus rau DC jack rau cov khoom siv hluav taws xob ruaj khov. Zuag qhia tag nrho, nws yog lub ntsaws-thiab- ua si ntaus ntawv uas yooj yim zog rau ntau lub ntsiab lus kawg hauv ib qho mus.

Deal rau ntau yam xwm txheej, qhov no PoE injector ci nyob rau hauv B2B ib puag ncig zoo li kev soj ntsuam kev ruaj ntseg, qhov twg nws powers IP koob yees duab nyob rau hauv ntev kev deb yam tsis muaj qhov chaw ntxiv. Nws kuj tseem zoo meej rau VoIP xov tooj tshuab hauv chaw ua haujlwm, kom ntseeg tau cov kab sib txuas lus meej. Hauv kev sib txuas lus wireless, nws txhawb nqa cov ntsiab lus nkag mus rau WiFi rau kev txuas ntxiv hauv cov tsev khaws khoom lossis teeb tsa sab nraum zoov. Lwm daim ntawv thov suav nrog cov txuas txuas txuas hluav taws xob, CPE cov khoom siv, lossis ib qho IEEE 802.3af / ntawm cov khoom siv sib xws hauv khw muag khoom, tos txais qhua, lossis chaw tsim khoom lag luam. Nws tsis yog - tus qauv passive txoj hauv kev ua rau nws muaj ntau yam rau kev teeb tsa kev cai uas tus qauv PoE yuav dhau los lossis tsis sib xws.

Thaum peb tsis muaj cov duab tshwj xeeb ntawm no, xav txog cov hnab yas compact uas muaj cov chaw nres nkoj kom meej meej: 4/8 RJ45 LAN inputs rau cov ntaub ntawv los ntawm koj lub qhov hloov lossis router, thiab sib piv PoE cov zis uas sib txuas cov ntaub ntawv thiab lub zog. Sab pem hauv ntej nta ib lub teeb ci LED uas ci tsis tu ncua thaum siv hluav taws xob, muab tswv yim rau koj tam sim. Nyob rau sab, DC lub qhov (socket) lees txais tus qauv 2.1 x 5.5 hli ntsaws, thiab lub davhlau ya nyob twg ntsuab ua kom muaj kev ruaj ntseg voltage input. Tus pin layout yog ncaj nraim-cov ntaub ntawv ntawm tus pins 1,2,3,6 thiab lub zog ntawm 4/5(+) thiab 7/8(-)-ua rau kev xaim intuitive rau cov kws tshaj lij.

Ntau tus neeg siv hauv kev sib txuas lus tau pom tias hom tshuaj txhaj no yog tus nqi - siv tau zoo rau tag nrho PoE keyboards, tshwj xeeb tshaj yog nyob rau hauv me me mus rau nruab nrab xa mus. Piv txwv li, nyob rau hauv tiag tiag - ntiaj teb teeb tsa, nws muaj kev ntseeg siab tau siv ntau lub koob yees duab IP hauv kev ruaj ntseg yam tsis muaj hluav taws xob poob, tsuav yog cov khoom siv sib xws nrog tus pin qauv. Kev lag luam tawm tswv yim qhia txog nws txoj kev sib raug zoo nrog tsis yog -PoE iav los ntawm kev sib cais, txo cov cabling clutter. Rov qab los ntawm cov txheej txheem Ethernet raws tu qauv, nws ua haujlwm tsis tu ncua hauv 10/100Mbps ib puag ncig, ua pov thawj nws tus nqi hauv kev txuas lub zog mus rau cov kev txwv Ethernet yam tsis muaj teeb liab degradation.

Peb muab qhov tseem ceeb rau koj qhov kev txaus siab nrog kev txhawb nqa dav dav rau cov neeg siv khoom B2B. Peb pab neeg muab kev sib tham ua ntej - kev yuav khoom los xyuas kom meej qhov sib haum nrog koj cov teeb tsa, suav nrog kev txiav txim ntau qhov txo nqi rau cov haujlwm loj. Tshaj tawm -muag, koj yuav nkag mus rau cov ncauj lus kom ntxaws txog kev teeb tsa thiab cov lus qhia daws teeb meem ntawm email lossis xov tooj. Peb kuj tseem muab cov qauv kev lees paub uas suav nrog kev tsim khoom tsis xws luag, ntxiv rau kev xaiv xa khoom sai kom txo qis sijhawm poob qis. Yog hais tias koj xav tau kev cai configurations los yog kev koom ua ke tswv yim, peb cov kws txawj nyob rau hauv no los pab ua kom koj deployment smooth.

Rau cov txiaj ntsig zoo tshaj plaws, pib los ntawm kev lees paub koj cov khoom siv 'PoE cov cai. Txuas cov chaw nres nkoj LAN rau koj qhov hloov Ethernet siv Cat.5 lossis zoo dua cables. Txuas cov chaw nres nkoj PoE rau koj cov khoom siv hluav taws xob, thiab ntsaws rau hauv 48V adapter rau DC lub qhov (socket). LED yuav teeb, qhia txog kev ua haujlwm. Ib txwm sim nyob rau hauv ib puag ncig tswj ua ntej, thiab nco ntsoov: passive PoE txhais tau hais tias lub zog tas li, yog li tshem tawm cov khoom siv tsis sib xws tam sim ntawd.
