Tilmaame qarsoon oo aad muhiim u ah ee furayaasha POE waa wadarta awoodda ay bixiso POE.Marka la eego heerka IEEE802.3af, haddii wadarta guud ee tamarta POE ee 24-dekedda POE beddelka ay gaadho 370W, markaa waxay bixin kartaa 24 dekedood (370/15.4=24), laakiin haddii ay tahay hal deked marka loo eego IEEE802.3at heerka, awoodda ugu badan Korontada waxaa lagu xisaabiyaa 30W, oo kaliya waxay siin kartaa koronto 12 dekedood ugu badnaan isku mar (370/30=12).

Si kastaba ha ahaatee, isticmaalka dhabta ah, isticmaalka tamarta ugu badan ee qalabyo badan oo hooseeya waa mid hooseeya.Tusaale ahaan, awoodda AP-yada-soo noqnoqda waa 6 ~ 8W.Haddii deked kasta oo POE ah ay kaydiso sahayda korontadu iyadoo loo eegayo awoodda ugu badan ee waqtigan, waxay soo baxaysaa awoodda POE ee dekedaha qaarkood aan la isticmaali karin, halka awoodda dekedaha qaarkood aan la qoondayn karin.Shidado badan oo POE ah ayaa taageera Qoondaynta Awooda Dhaqdhaqaaqa (DPA).Sidan oo kale, deked kastaa waxay u qoondaynaysaa oo kaliya awoodda dhabta ah ee la isticmaalo, si tamarta uu keeno shideeyaha POE si hufan looga faa'iidaysan karo.

Aynu malo-awaal samayno, haddii aan isticmaalno furaha 24-deked ee POEJHA-P420024BTHiyo kooxda hal-band ah nooca JHA-MB2150X.Waxaan u qaadaneynaa in awoodda POE ee JHA-P420024BTH ay tahay 185W (Fiiro gaar ah: awoodda 24-dekedood POE beddelka JHA-P420024BTH waa 380W).12 dekedood ayaa ku shaqeeya, ka dib markii awood qaybsi firfircoon la qaatay, sababtoo ah isticmaalka awoodda ugu badan ee JHA-MB2150X waa 7W, JHA-P420024BTH waxay awood u siin kartaa 24 panels ee JHA-MB2150X (185/7=26.4).
