Ngokunyuka kokuthandwa kwefowuni ye-IP, ukujongwa kwevidiyo yenethiwekhi kunye nezixhobo ze-Ethernet ezingenazintambo kwinethiwekhi, imfuno yokubonelela ngenkxaso yamandla nge-Ethernet ngokwayo iya ingxamiseka ngakumbi. Kwiimeko ezininzi, isixhobo se-terminal sifuna unikezelo lwamandla e-DC, kwaye isixhobo setheminali siqhele ukufakwa kwisilingi okanye ngaphandle phezulu ukusuka emhlabeni. Kunzima ukuba nesokethi yamandla efanelekileyo ekufutshane. Nokuba kukho i-socket, i-AC / DC converter efunwa sisixhobo se-terminal kunzima ukubekwa. Ukongeza, kwizicelo ezininzi ze-LAN ezinkulu, abalawuli kufuneka balawule izixhobo ezininzi zetheminali ngexesha elinye. Ezi zixhobo zidinga umbane odibeneyo kunye nolawulo olumanyeneyo. Ngenxa yokuthintelwa kwendawo yonikezelo lwamandla, kuzisa inkxwaleko enkulu kulawulo lonikezelo lombane. Ubonelelo lwamandla e-Ethernet Poe isombulula le ngxaki.

I-Poe yitekhnoloji yobonelelo lwamandla e-Ethernet enentambo. Intambo yenethiwekhi esetyenziselwa ukuhanjiswa kwedatha inamandla ombane we-DC ngaxeshanye, enokusombulula ngokufanelekileyo unikezelo lwamandla oluphakathi kweetheminali ezifana ne-IP yefowuni, i-AP engenazintambo, itshaja yesixhobo esiphathwayo, umfundi wekhadi, ikhamera kunye nokufumana idatha. Ubonelelo lwamandla ePoe luneenzuzo zokuthembeka, uqhagamshelo olulula kunye nomgangatho odibeneyo:

Ithembekile: isixhobo sePoe sinokubonelela ngamandla kwizixhobo ezininzi zetheminali ngaxeshanye, ukuze kuphunyezwe unikezelo lwamandla oluphakathi nendawo kunye nokugcinwa kwamandla ngaxeshanye. Uxhulumaniso olulula: izixhobo ze-terminal azidingi ukunikezelwa kwamandla angaphandle, kodwa intambo enye kuphela yenethiwekhi. Umgangatho: thobela imigangatho yamazwe ngamazwe kwaye usebenzise ujongano lwamandla olumanyeneyo lwe-RJ45 ukuze uqinisekise uqhagamshelo nezixhobo ezivela kubavelisi abahlukeneyo.
