      Umgomo we-POE wokunikezwa kwamandla kanye nenqubo yokuphakelwa kwamandla

      1 Isingeniso I-PoE ibizwa nangokuthi i-Power over LAN (PoL) noma i-Active Ethernet, ngezinye izikhathi ebizwa ngokuthi Amandla phezu kwe-Ethernet ngamafuphi. Lokhu ukucaciswa okujwayelekile kwakamuva okusebenzisa izintambo zokudlulisa ezijwayelekile ze-Ethernet ukuze kudluliswe idatha namandla ngesikhathi esifanayo, futhi kugcine ukuhambisana...
