Kodi mukudziwa momwe mungasankhire chosinthira cha PoE?

PoE ndiukadaulo womwe umapereka mphamvu ndi kufalitsa kwa data kudzera pa zingwe zama network.Chingwe chimodzi chokha cha netiweki chimafunika kuti chilumikizidwe ku kamera ya PoE, popanda kufunikira kwa waya wowonjezera.

Chipangizo cha PSE ndi chipangizo chomwe chimapereka mphamvu ku chipangizo cha Ethernet kasitomala, komanso ndi woyang'anira mphamvu yonse ya POE pa njira ya Ethernet.Chipangizo cha PD ndi katundu wa PSE womwe umalandira mphamvu, ndiko kuti, chipangizo cha kasitomala cha dongosolo la POE, monga foni ya IP, kamera yotetezera maukonde, AP, wothandizira digito kapena foni yam'manja ndi zipangizo zina zambiri za Ethernet (makamaka, chilichonse chipangizo chokhala ndi mphamvu zosakwana 13W chikhoza kupeza mphamvu zofanana kuchokera ku socket ya RJ45).Awiriwa amakhazikitsa maulumikizidwe azidziwitso potengera muyezo wa IEEE 802.3af wokhudza momwe kulumikizana, mtundu wa chipangizocho, mulingo wogwiritsa ntchito mphamvu, ndi mbali zina za chipangizo cholandirira PD, ndipo amagwiritsa ntchito izi ngati maziko a PSE kuti apangitse mphamvu PD kudzera pa Ethernet.

Posankha kusintha kwa PoE, mfundo zotsatirazi ziyenera kuganiziridwa:

1. Mphamvu ya doko limodzi

Tsimikizirani mphamvu ya doko limodzi ikukwaniritsa mphamvu yayikulu ya IPC iliyonse yolumikizidwa ndi switch kapena ayi.Ngati inde, sankhani zosintha potengera mphamvu yayikulu ya IPC.

Mphamvu ya PoE IPC yokhazikika sikudutsa 10W, kotero chosinthira chimangofunika kuthandizira 802.3af.Koma ngati mphamvu yamagetsi yamakina ena othamanga kwambiri ndi pafupifupi 20W, kapena ngati mphamvu ya ma AP ena opanda zingwe ndi apamwamba, ndiye kuti kusinthaku kukufunika kuthandizira 802.3at.

Zotsatirazi ndi mphamvu zotulutsa zofanana ndi matekinoloje awiriwa:
