    Isesengura ry'ikoranabuhanga rya POE

    Igihe cyo kohereza: Jun-17-2021

    UwitekaGuhindura PoEni ahinduraishyigikira amashanyarazi kumurongo. Ugereranije nibisanzwehindura, ingufu zakira itumanaho (nka AP, kamera ya digitale, nibindi) ntikeneye kuba insinga kugirango itange amashanyarazi, kandi kwizerwa kwurusobe rwose ni hejuru.

    Incamake yimbaraga hejuru ya Ethernet (POE) POE (Imbaraga Zirenga Ethernet) bivuga ikoreshwa rya terefone ishingiye kuri IP (nka terefone ya IP, imiyoboro ya LAN itagikoreshwa (AP, kamera y'urusobe, nibindi) irashobora gutanga tekinoroji ya DC yo gutanga amashanyarazi kubyo ibikoresho mugihe cyohereza ibimenyetso byamakuru tekinoroji ya POE irashobora kwemeza imikorere isanzwe y'urusobe ruriho mugihe umutekano wumutekano wubatswe uriho, kugabanya ibiciro.

    POE izwi kandi nka sisitemu yo gutanga amashanyarazi ashingiye kumurongo waho (POL, Power over LAN) cyangwa Ethernet Active (Active Ethernet), rimwe na rimwe nanone yitwa Power over Ethernet mugihe gito. Ubu ni bwo buryo bwo gukoresha insinga zisanzwe za Ethernet zohereza amakuru hamwe nimbaraga zamashanyarazi icyarimwe Ibipimo bigezweho nibisobanuro, kandi bigakomeza guhuza na sisitemu ya Ethernet hamwe nabakoresha. IEEE

    Igipimo cya 802.3af nigipimo gishya gishingiye kuri POE ya sisitemu yo gutanga amashanyarazi ya Ethernet. Yongeyeho ibipimo bifitanye isano no gutanga amashanyarazi ataziguye binyuze mumurongo wa neti hashingiwe kuri IEEE802.3. Nukwagura ibipimo bisanzwe bya Ethernet nibisanzwe mpuzamahanga byo gukwirakwiza ingufu. bisanzwe.

    IEEE yatangiye guteza imbere ibipimo mu 1999, kandi abacuruzi ba mbere bitabiriye ni 3Com, Intel, PowerDsine, Nortel, Mitel, na Semiconductor yigihugu. Ariko, ibitagenda neza muriki gipimo byagabanije kwagura isoko. Kugeza muri Kamena 2003, IEEE yemeje 802.3af isanzwe, igaragaza neza ibibazo byo kumenya ingufu no kugenzura ingufu muri sisitemu ya kure, kandi ihuzaRouters, guhinduranya, hamwe na hub kuri terefone ya IP, sisitemu yumutekano, hamwe na LAN itagikoreshwa hifashishijwe insinga za Ethernet. Uburyo bwo gutanga amashanyarazi bwibikoresho birateganijwe. Iterambere rya IEEE802.3af ririmo imbaraga zinzobere nyinshi zamasosiyete, nazo zituma ibipimo bipimwa mubice byose.
