Ushbu maqolada Power over Ethernet (PoE) texnologiyasining mohiyati, uning kommutator va marshrutizatorlarda qo‘llanish mexanizmlari, passiv va standartlashtirilgan PoE yechimlari, 48–55 V kabelli quvvatlanish tizimlari, A va B sxemalaridagi uzatish prinsiplari, shuningdek IEEE 802.3af/at standartlarining texnik imkoniyatlari yoritiladi. PoE texnologiyasi kam quvvat iste’mol qiluvchi qurilmalarni alohida elektr tarmoqlaridan foydalanmasdan tarmoq kabeli orqali quvvatlantirishga imkon berishi sababli, zamonaviy tarmoq infratuzilmasining ajralmas qismiga aylangan. Maqolada kabel qarshiligi, quvvat sinflari, liniya uzunligi va xavfsizlik masalalari ham tahlil qilinadi.
