I-POE (amandla phezu kwe-Ethernet) ibhekisela kwiteknoloji yokuhambisa amandla ngentambo yenethiwekhi.Ngoncedo lwe-Ethernet ekhoyo, inokudlulisa idatha kunye nokubonelela ngamandla kwizixhobo ze-terminal ze-IP (ezifana ne-IP yefowuni, i-AP, ikhamera ye-IP, njl.) ngentambo yenethiwekhi.

I-Poe ikwaziwa njengamandla phezu kwe-LAN (POL) okanye i-Ethernet esebenzayo, ngamanye amaxesha ibizwa ngokuba ngumbane we-Ethernet.

Ukwenzela ukubeka emgangathweni nokukhuthaza uphuhliso lobuchwepheshe bonikezelo lwamandla ePoe kunye nokusombulula ingxaki yokuguquguquka phakathi konikezelo lwamandla kunye nezixhobo zokufumana amandla ezivela kubenzi abahlukeneyo, ikomiti yemigangatho ye-IEEE iye yakhupha ngokulandelelana imigangatho emithathu yePoe: umgangatho we-IEEE 802.3af, IEEE 802.3 kumgangatho kunye IEEE 802.3bt umgangatho.
