I-POE (amandla phezu kwe-Ethernet) ibhekisela kubuchwepheshe bokudlulisa amandla ngentambo yenethiwekhi.Ngosizo lwe-Ethernet ekhona, ingadlulisela kanyekanye idatha futhi inikeze amandla kumishini yetheminali ye-IP (njengefoni ye-IP, i-AP, ikhamera ye-IP, njll.) ngentambo yenethiwekhi.

I-Poe yaziwa nangokuthi amandla phezu kwe-LAN (POL) noma i-Ethernet esebenzayo, kwesinye isikhathi ebizwa ngokuthi yi-Ethernet power supply.

Ukuze kumiswe futhi kugqugquzelwe ukuthuthukiswa kobuchwepheshe bokuphakelwa kwamandla ka-Poe futhi kuxazululwe inkinga yokuvumelana nezimo phakathi kokuphakelwa kukagesi nezisetshenziswa zokwamukela amandla ezivela kubakhiqizi abahlukene, ikomidi lamazinga le-IEEE likhiphe ngokulandelana amazinga amathathu e-Poe: IEEE 802.3af standard, IEEE 802.3at standard and I-IEEE 802.3bt ejwayelekile.
