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 kwimveliUkutshintsha kwe-Ethernet, kunye nokongezwa komsebenzi we-PoE ngaphakathi, ukwenzela ukuba ukutshintshwa kungabi nomsebenzi wokutshintshiselana kwedatha kuphela, kodwa kunokudlulisa amandla ngekhebula lomnatha ngexesha elifanayo.Olu lutshintsho lonikezelo lwamandla womnatha.Iyakwazi ukwahlula kwiinguqu eziqhelekileyo kwimbonakalo.Iiswitshi ze-PoE zinegama elithi "PoE" phambi kwephaneli, ebonisa ukuba banemisebenzi ye-PoE, ngelixa iiswitshi eziqhelekileyo zingenayo.
Ukuqonda unikezelo lwamandla enethiwekhi ngokutshintsha kwePoE kuneenzuzo ezininzi.
1.Ukusasazwa okulula.Akukho mfuneko yokwemba imingxunya, ukutsala iintambo, okanye ukufaka iziseko zombane ukuze usebenzise iPoE.Ufuna enye kuphelaIzibuko le-RJ45ukubonelela ngeendlela ezahlukeneyo zonikezelo lwamandla kwizixhobo kwiindawo ezahlukeneyo nge-Ethernet ekhoyo.
2.Okubhetyebhetye ngakumbi.Nge-PoE, indawo yokufakela iikhamera zenethiwekhi kunye neendawo zokufikelela ezingenazintambo azisathintelwa.Kungakhathaliseki ukuba ikude kangakanani i-socket yamandla e-AC, inokuthunyelwa naphi na apho ifuneka khona, nto leyo eyenza ukuba iliso lomnatha ligqibelele ngakumbi.
3.Ikhuseleke ngakumbi.Xa kuthelekiswa nombane we-AC,Ubonelelo lwamandla e-PoEyeyoluhlu lwangoku olubuthathaka, kwaye akukho mngcipheko wokhuseleko lwangoku olomeleleyo.Ngaphezu koko, amandla anikezelwa ngentambo yenethiwekhi.Kuphela xa izixhobo ezifuna ukunikezelwa kwamandla zixhunyiwe, intambo ye-Ethernet iya kuba ne-voltage, isusa umngcipheko wokuvuza kumgca.
4.Ixabiso eliphantsi.Iindleko ezikhankanywe apha azibhekiseli kuphela kwimali, kodwa zibandakanya iindleko zexesha.Iintambo zamandla emveli zifuna iindleko zabasebenzi kwaye zifuna ixesha elithile lokugqiba, nto leyo yindleko enkulu.Isebenzisa kuphela iswitshi ye-PoE yonikezelo lwamandla, akukho msebenzi wezandla okanye ixesha elininzi, ngokusisiseko iplagi kunye nokudlala, ilula kakhulu, iluncedo kwaye iyakhawuleza.
5.Ulawulo olulula.Ulawulo lwenkqubo yokubeka iliso yemveli kunye nokugcinwa kunzima kakhulu kwaye kunzima.Ukusebenzisa umbane we-PoE unokulawula ukude, ukulungelelanisa okanye ukusetha kwakhona iikhamera zenethiwekhi kunye neendawo zokufikelela ezingenazintambo.
Iiswitshi zePoEukubonelela ngeekhamera zenethiwekhi ngokuphuculwa kokuthembeka, ukunciphisa iindleko, kunye nokulula kokuthunyelwa.Ngophuhliso olunamandla lokucupha inethiwekhi, ngakumbi nangakumbi iikhamera zenethiwekhi zinokunikwa amandla yi-PoE.
