ʻO kahi hōʻailona huna koʻikoʻi o nā hoʻololi POE ʻo ka nui o ka mana i hāʻawi ʻia e POE.Ma lalo o ka IEEE802.3af maʻamau, ina ka huina POE mana lako o ka 24-puka POE kuapo hiki i 370W, a laila hiki ke hoolako i 24 awa (370/15.4=24), akā, ina he hookahi awa e like me ka IEEE802.3at. maʻamau, ka mana kiʻekiʻe Ua helu ʻia ka mana lako ma 30W, a hiki iā ia ke hāʻawi wale i ka mana i nā awa 12 i ka nui i ka manawa like (370/30=12).

Eia nō naʻe, i ka hoʻohana maoli ʻana, ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana i ka mana o nā mea haʻahaʻa haʻahaʻa.No ka laʻana, ʻo ka mana o nā AP hoʻokahi-frequency ʻo 6 ~ 8W.Inā mālama kēlā me kēia awa POE i ka mana e like me ka mana kiʻekiʻe i kēia manawa, e ʻike ʻia ʻAʻole hiki ke hoʻohana ʻia ka mana POE o kekahi mau awa, ʻoiai ʻaʻole hiki ke hoʻokaʻawale ʻia ka mana o kekahi mau awa.Nui nā hoʻololi POE e kākoʻo i ka Dynamic Power Allocation (DPA).Ma kēia ala, hoʻokaʻawale kēlā me kēia awa i ka mana i hoʻohana maoli ʻia, i hiki ke hoʻohana pono ʻia ka mana i hāʻawi ʻia e ka POE.

E hana mākou i kahi manaʻo, inā mākou e hoʻohana i ka hoʻololi POE 24-portJHA-P420024BTHa me ke ʻano o ka panel hui hoʻokahi JHA-MB2150X.Manaʻo mākou he 185W ka mana POE o ka JHA-P420024BTH (E hoʻomaopopo: ʻo ka mana o ka 24-port POE hoʻololi JHA-P420024BTH ʻo 380W).Hoʻohana ʻia nā awa 12, a ma hope o ka lawe ʻia ʻana o ka mana ikaika, no ka mea, ʻo ka nui o ka hoʻohana mana o JHA-MB2150X he 7W, hiki iā JHA-P420024BTH ke mana i nā panela 24 o JHA-MB2150X (185/7=26.4).
