Ib qho tseem ceeb heev zais qhov taw qhia ntawm POE keyboards yog tag nrho lub zog muab los ntawm POE.Raws li tus qauv IEEE802.3af, yog tias tag nrho POE fais fab mov ntawm 24-chaw nres nkoj POE hloov mus txog 370W, ces nws tuaj yeem muab 24 qhov chaw nres nkoj (370/15.4 = 24), tab sis yog tias nws yog ib qho chaw nres nkoj raws li IEEE802.3at tus qauv, lub zog siab tshaj plaws Cov khoom siv hluav taws xob suav nrog 30W, thiab nws tsuas tuaj yeem muab lub zog rau 12 qhov chaw nres nkoj feem ntau tib lub sijhawm (370/30 = 12).

Txawm li cas los xij, hauv kev siv tiag tiag, qhov siab tshaj plaws ntawm kev siv hluav taws xob ntau ntawm cov khoom siv hluav taws xob tsawg yog qhov tsawg.Piv txwv li, lub zog ntawm ib zaus APs yog 6 ~ 8W.Yog tias txhua qhov chaw nres nkoj POE khaws cov khoom siv hluav taws xob raws li lub zog siab tshaj plaws nyob rau lub sijhawm no, nws yuav tshwm sim Lub zog POE ntawm qee qhov chaw nres nkoj siv tsis tau, thaum lub zog ntawm qee qhov chaw nres nkoj tsis tuaj yeem faib.Ntau lub POE hloov pauv txhawb Dynamic Power Allocation (DPA).Nyob rau hauv txoj kev no, txhua qhov chaw nres nkoj tsuas yog faib lub zog siv tiag tiag, kom lub zog muab los ntawm POE hloov tau siv tau zoo dua.

Cia peb ua qhov kev xav, yog tias peb siv 24-chaw nres nkoj POE hloovJHA-P420024BTHthiab ib leeg-band vaj huam sib luag hom JHA-MB2150X.Peb xav tias lub zog POE ntawm JHA-P420024BTH yog 185W (Ceeb Toom: lub zog ntawm 24-chaw nres nkoj POE hloov JHA-P420024BTH yog 380W).12 qhov chaw nres nkoj tau siv zog, thiab tom qab siv lub zog hluav taws xob zoo, vim tias qhov siab tshaj plaws ntawm kev siv hluav taws xob ntawm JHA-MB2150X yog 7W, JHA-P420024BTH tuaj yeem siv tau 24 lub vaj huam sib luag ntawm JHA-MB2150X (185/7 = 26.4).
