POE injector: isiqu, inkcazo

POE injector - divaysi womnatha eziziziqalelo ukuba lula kakhulu ukufakelwa kwezixhobo womnatha kwi kwishishini okanye kwi-ofisi. technology POE (PowerOver Ethernet) uvumela amnike izixhobo womnatha nge intambo womnatha, ngaleyo ndlela asuse lo izixhobo ukusuka imfuneko ukufaka iintambo zombane kwiindawo apho kukho izinto lingavumi kunye enkulu namandla.

Makhe sijonge amancedo isixhobo ezifana POE injector amandla. Xa sifakwe kwi-ofisi Wi-Fi iindawo zokungena, iikhamera network, okanye umzila, kufuneka uthathe ingqalelo, iphi na lo walivala ithende elikufutshane (220 volts) ukudibanisa iiyunithi umbane eso sixhobo. Amaxesha amaninzi, oku kakhulu ukunciphisa iinketho zakho. Amaxesha amaninzi, ukuze ufumane inqanaba ilungileyo umqondiso Wi-Fi, kuyimfuneko ukubeka kwindawo ephakamileyo, umzekelo, kwi eluphahleni. Kule meko kuyimfuneko, okanye ukubaleka iintambo ukufaka entsha kwi yophahla, okanye ukuba ibingelele umgangatho umqondiso afakele izixhobo apho umbane ivumela. Kwaye ukuba ufuna ukufaka izixhobo womnatha kwiindawo ezisemaphandleni (phezu kwendlu, imbala, njalo njalo), ngoko ke ixabiso iintambo kunye nofakelo iziseko kunokuba phezulu kakhulu. Ukusombulula le ngxaki IEEE 802.3AF esezantsi zadalwa, nto leyo evumela ukuba ukudlulisela nge ombane Ethernet. Ukuqinisekisa ukusebenza yamacebo na iintambo ngokwaneleyo ezikhoyo lesithathu okanye sesihlanu didi. Mu kuya kwa nshita volts 220, apho umbane nakwesiphi zonke izixhobo odlayo amandla-, POE injector isasaze amandla kwisixhobo ngasinye.

Ekubeni zonke izixhobo zekhompyutha kuxhaswa yi ngoku ngqo, umgangatho POE lithathele yokosulela nge cable a DC ombane ukuya kwisibini ephothiweyo kuluhlu ukusuka volts 44 ukuya 57 volts. Eli xabiso wakhethwa ngenxa yokuba ingenziwa ukuba iintambo ye sibini ephothiweyo ngaphandle ukulinganiselwa ubude. Ukugqithisa of current zombane kwi intambo ezi izibini ezibini, phezu ngamnye kubo ukubonelwa ezikhoyo kuluhlu milliamperes 175 (350 ma iyonke). Ngako oko, amandla isixhobo ezifana POE injector unako ukufikelela watts 16. Oku kungaphezulu kuno ezaneleyo ukuze amnike izixhobo womnatha.

Enyanisweni, i-POE injector - kwisixhobo ezithwala umboniso intambo ngamandla ombane. Esi sixhobo adityaniswe kwi izixhobo womnatha (umzila) okanye iqwalaselwe nje isixhobo elizimeleyo. Kwimeko yokugqibela, lo injector POE uqhagamshele kwisibini ephothiweyo, ukuba liqatywe ukuya 220 volts. Xa ze data igalelo ukuya kwisixhobo, kwaye imveliso - le ombane kunye data.

Xa ndiqukumbela, sidibanisa ukuba iteknoloji POE kukhawulweyo njengethuba yokunciphisa iindleko ngelixa Yokutshayelela uthungelwano kwii-ofisi kunye neefektri. Noko ke, ngokukhawuleza wazuza popularity and kwicandelo labucala, njengoko lula kakhulu uxhulumaniso kwezixhobo womnatha khipha inani okungeyomfuneko elikhulu unikezelo lombane.
