Isalathisi esibaluleke kakhulu esifihliweyo sokutshintsha kwe-POE ngamandla onke anikezelwa yi-POE.Ngaphantsi komgangatho we-IEEE802.3af, ukuba umbane opheleleyo we-POE we-24-port POE switch ufikelela kwi-370W, ngoko unokubonelela ngezibuko ezingama-24 (370 / 15.4 = 24), kodwa ukuba ichweba elinye ngokwe-IEEE802.3at umgangatho, ubuninzi bamandla Unikezelo lwamandla lubalwa kwi-30W, kwaye lunokubonelela kuphela umbane kwizibuko ezili-12 kakhulu ngexesha elinye (370/30=12).

Nangona kunjalo, ekusetyenzisweni okwenyani, ukusetyenziswa kwamandla aphezulu kwizixhobo ezininzi zamandla aphantsi kuphantsi.Umzekelo, amandla e-APs ye-single-frequency yi-6 ~ 8W.Ukuba izibuko le-POE ngalinye ligcina unikezelo lwamandla ngokowona mandla maninzi ngeli xesha, liza kubonakala Amandla e-POE kwamanye amazibuko akanakusetyenziswa, ngelixa amandla amanye amazibuko engenakwabiwa.Iiswitshi ezininzi ze-POE zixhasa i-Dynamic Power Allocation (DPA).Ngale ndlela, izibuko ngalinye labela kuphela amandla asetyenzisiweyo ngokwenene, ukuze amandla anikezelwe lutshintsho lwe-POE asetyenziswe ngokufanelekileyo.

Masenze ingqikelelo, ukuba sisebenzisa i-24-port POE switchI-JHA-P420024BTHkunye nohlobo lwephaneli yeqela elinye JHA-MB2150X.Sicinga ukuba amandla e-POE e-JHA-P420024BTH yi-185W (Qaphela: amandla e-24-port POE switch JHA-P420024BTH yi-380W).Izibuko ze-12 zinikwe amandla, kwaye emva kokuhanjiswa kwamandla okuguquguqukayo kwamkelwe, ngenxa yokuba ukusetyenziswa kwamandla aphezulu kwe-JHA-MB2150X yi-7W, i-JHA-P420024BTH inokunika amandla iipaneli ze-24 ze-JHA-MB2150X (185/7 = 26.4).
