POE Injector: lakuti, ofotokoza

POE Injector - ndi maziko maukonde chipangizo kwakukulu zimatithandiza unsembe zipangizo zopezera mu ogwira ntchito kapena mu ofesi. POE luso (PowerOver Efaneti) amalola powering zipangizo zopezera kudzera chingwe network potero adzathetsa zida izi kuchokera kufunika kukhazikitsa malo ogulitsira magetsi m'madera ndi katundu azigona ndi bulky mphamvu.

Tiyeni tione ubwino wa chipangizo monga POE injector mphamvu. Pamene anaika mu ofesi Wi-Fi kupeza mfundo makamera network kapena rauta, muyenera kuganizira, komwe ndi kubwereketsa yapafupi (220 volts) kugwirizanitsa mayunitsi magetsi pa zida zimenezi. Nthawi zambiri imeneyi akhoza kuchepetsa mungagwire. Nthawi zambiri, pofuna kupeza mlingo yabwino ya Wi-Fi chizindikiro, m'pofunika ikani kupeza mfundo apamwamba Mwachitsanzo, pa denga. Pankhaniyi m'pofunika, kapena kuthamanga Kulumikizana ndi kukhazikitsa njira ina pa denga, kapena nsembe khalidwe la chizindikiro ndi kukhazikitsa zida kumene magetsi amalola. Ndipo ngati muyenera kuika zipangizo zopezera mu m'madera akutali (pa denga, chapamwamba, ndi zina zotero), ndiye mtengo wa Kulumikizana ndi zokhazikapo unsembe kungakhale kwambiri. Kuti athetse vutoli muyezo IEEE 802.3AF analengedwa, amene amalola inu kusamutsa kudzera Efaneti magetsi panopa. Kuti ntchito zipangizo ndi zokwanira zingwe wogwila wachitatu kapena chachisanu gulu. Mosiyana ndi volts 220, kumene magetsi umaperekedwa kwa zipangizo zonse mphamvu yambiri, POE injector kugawira mphamvu lililonse chipangizo payekha.

Popeza zida kompyuta ali zoyendetsedwa ndi panopa mwachindunji, ndi POE muyezo adzatenge HIV ndi chingwe ndi DC voteji kwa anthu awiri zopotoka mu osiyanasiyana kuchokera 44 volts kuti volts 57. Khalidwe limeneli anasankhidwa chifukwa zikhoza kupangidwa kwa zingwe za nsapato zopotoka popanda zofooka mu nthawi. Pakuti kufala kwa magetsi mu chingwe ali ndi mitundu iwiri iwiri, pa aliyense wa iwo aziwapatsa panopa mu osiyanasiyana 175 milliamperes (350 MA mu okwana). Choncho, mphamvu ya chipangizo monga POE injector angafikire 16 Watts. Izi kuposa zokwanira powering zipangizo zopezera.

Ndipotu POE injector - chipangizo kuti transmits chizindikiro mu chingwe ndi mphamvu ya magetsi. chipangizo Izi akhoza Integrated mu zopezera zida (rauta) kapena kukhazikitsidwa monga chipangizo wodziimira. Zikatero, ndi POE injector olumikizidwa kwa awiri zopotoka ndi ang'ambe thupilo kuti volts 220. Kamodzi deta ndi athandizira kwa chipangizo, ndi pa linanena bungwe - ndi voteji ndi deta.

Pomaliza, kuwonjezera kuti luso POE cholandiridwa ngati mwayi kuchepetsa pamene broaching Intaneti m'maofesi komanso mafakitale. Komabe, ndithu mofulumira zinatchuka ndi mu gawo payekha, monga kwambiri zimatithandiza kugwirizana zipangizo zopezera ndi kumatha zosafunika ambiri amapereka mphamvu.
