Ngaphambi kokuba siqonde utshintsho lwe-PoE, kufuneka siqale siqonde ukuba yintoni i-PoE.
I-PoE lubonelelo lwamandla ngaphezulu kwetekhnoloji ye-Ethernet.Yindlela yokubonelela ngokude amandla kwizixhobo zenethiwekhi ezixhunyiwe (ezifana ne-Wireless LAN AP, i-IP Phone, iBluetooth AP, ikhamera ye-IP, njl.) Isixhobo se-terminal network ye-IP senza ukuba kube yimfuneko ukusasaza inkqubo yonikezelo lwamandla eyahlukileyo kwisixhobo kwindawo yokusetyenziswa, enokunciphisa kakhulu ukubiyelwa kweengcingo kunye neendleko zolawulo lokusebenzisa izixhobo zetheminali nokukhuthaza uphuhliso lwemimandla enxulumeneyo.
IUkutshintsha kwePoEisekelwe kwinguqu ye-Ethernet yendabuko, kunye nokongezwa komsebenzi we-PoE ngaphakathi, ukwenzela ukuba ukutshintshwa kungabi nje umsebenzi wokutshintshiselana kwedatha, kodwa kunokudlulisa amandla ngentambo yenethiwekhi ngexesha elifanayo.Olu lutshintsho lonikezelo lwamandla womnatha.Iyakwazi ukwahlula kwiinguqu eziqhelekileyo kwimbonakalo.Iiswitshi zePoEbabe negama elithi "PoE" ngaphambili kwendawo yolawulo, ebonisa ukuba banemisebenzi ye-PoE, ngelixa iiswitshi eziqhelekileyo zingenayo.
1. Ukhuseleko ngakumbi
Sonke siyazi ukuba i-220V yombane iyingozi kakhulu.Iintambo zonikezelo lwamandla zihlala zonakele.Oku kuyingozi kakhulu, ngakumbi kwiindudumo.Emva kokuba isixhobo sokufumana amandla sonakaliswe, into eyenzeka ngokuvuza ayinakuphepheka.Ukusetyenziswa kweIiswitshi zePoEikhuseleke ngakumbi.Okokuqala, akukho mfuneko yokutsala umbane, kwaye inika i-voltage ekhuselekileyo ye-48V.
2. Ukulungeleka ngakumbi
Phambi kokuxhaphaka kwetekhnoloji yePoE, iisokethi zamandla ezingama-220V zazisetyenziselwa ukubonelela ngombane.Le ndlela yokwakha inzima, kuba akusiyo yonke indawo enokuthi inikwe amandla okanye ifakwe, ngoko ke indawo engcono kakhulu yekhamera isoloko ithintelwa yimiba eyahlukeneyo Indawo kufuneka itshintshwe, nto leyo ebangela ukuba kubekho iindawo ezininzi ezingaboniyo zokubeka iliso.Emva kokuba iteknoloji ye-PoE ikhulile, ezi zinokusonjululwa.Emva kwayo yonke loo nto, intambo yenethiwekhi inokunikwa amandla yiPoE.
3. Ubhetyebhetye ngakumbi
Indlela yokudibanisa yendabuko iya kuchaphazela uthungelwano lwenkqubo yokubeka iliso, okubangela ukungakwazi ukufaka ukubeka iliso kwezinye iindawo ezingafanelekanga kwi-wiring.Nangona kunjalo, ukuba utshintsho lwe-PoE lusetyenziselwa ukunikezelwa kwamandla, alukhawulelwanga ngexesha, indawo kunye nokusingqongileyo, kwaye indlela yothungelwano iya kuba nayo Ubuninzi bokuguquguquka, ikhamera inokufakwa ngokungekho mthethweni.
4. Okonga amandla ngakumbi
Indlela yonikezelo lwamandla yemveli ye-220V idinga uluhlu olubanzi lweengcingo.Kwinkqubo yothumelo, ilahleko inkulu kakhulu.Okukhona umgama omde, kokukhona ilahleko inkulu.Itekhnoloji yamva nje ye-PoE isebenzisa itekhnoloji enekhabhoni ephantsi kunye neyokusingqongileyo enelahleko encinci kakhulu.Ngokombono wayo, ukonga amandla kunye nokukhuselwa kwendalo kunokufezekiswa.
5. Intle ngakumbi
Ngenxa yokuba iteknoloji ye-POE yenza uthungelwano kunye nombane ube yinto enye, akukho mfuneko yocingo kunye nokufaka iisokethi kuyo yonke indawo, eyenza indawo yokubeka iliso ibonakale imfutshane kwaye inesisa.Umbane we-POE unikwe amandla yintambo yenethiwekhi, oko kukuthi, intambo yenethiwekhi ehambisa idatha inokudlulisa kwakhona amandla , Oku akugcini nje ukwenza lula inkqubo yokwakha, ukunciphisa iindleko zokufakela, kwaye kukhuselekile.Phakathi kwazo, iiswitshi ze-POE zithandwa kakhulu ziinjineli zokhuseleko ngokusebenza kwazo okuphezulu, ukusetyenziswa okulula nokufanelekileyo, ulawulo olulula, uthungelwano olufanelekileyo, kunye neendleko eziphantsi zokwakha.
