Kodi Mphamvu pa Ethernet (POE) ndi chiyani

Mphamvu pa Ethernet (PoE) ndiukadaulo wosinthika womwe umathandizira zingwe zama netiweki kutumiza mphamvu zamagetsi ku zida zosiyanasiyana mkati mwa netiweki, ndikuchotsa kufunikira kwa malo opangira magetsi kapena ma adapter. Njirayi imathandizira kuyika kwa zida, chifukwa zimatha kulandira mphamvu ndi deta kudzera pa chingwe chimodzi, zomwe zimapangitsa kuti zikhale zosavuta komanso zogwira ntchito pomanga zomangamanga.

Kodi Zingwe Zonse za Ethernet Zimathandizira PoE?

Sizingwe zonse za Ethernet zomwe zimapangidwa mofanana zikafika pothandizira PoE. Ngakhale zingwe za Cat5e kapena zapamwamba za Efaneti zimatha kuthandizira PoE, zingwe za Cat5 zitha kungogwira ma voltages otsika. Kugwiritsa ntchito zingwe za Cat5 kuti muyambitse zida za Class 3 kapena Class 4 Powered Devices (PDs) zitha kuyambitsa zovuta. Chifukwa chake, ndikofunikira kusankha chingwe choyenera pazosowa zanu za PoE.

Mapulogalamu a PoE

Kusinthasintha kwa PoE kumaphatikizapo ntchito zosiyanasiyana m'magawo osiyanasiyana. Zida zina zodziwika bwino zomwe zitha kuyendetsedwa kudzera pa PoE ndi:

Kuunikira kwa LED, ma Kiosks, masensa okhala, ma Alarm, Makamera, Monitor, Window shades, ma laputopu otha USB-C, zowongolera mpweya, ndi Mafiriji.

Kupititsa patsogolo Miyezo ya PoE

Muyezo waposachedwa kwambiri muukadaulo wa PoE umadziwika kuti Hi PoE (802.3bt Type 4), womwe umatha kupereka mphamvu zofikira 100 W kudzera pazingwe za Cat5e. Kukula kumeneku kumapangitsa kuti pakhale mphamvu zowonjezera zida zogwiritsa ntchito mphamvu zambiri, kulimbikitsa luso komanso magwiridwe antchito. Komabe, ndikofunikira kuzindikira kuti kuwonjezereka kwamagetsi kumatha kubweretsa kutentha kwakukulu komanso kutayika kwamagetsi mkati mwa chingwe.

Malangizo Ogwiritsa Ntchito Moyenera PoE

Kuti muchepetse zovuta zokhudzana ndi kutentha ndi kutaya mphamvu, akatswiri amalimbikitsa kugwiritsa ntchito zingwe zamkuwa zamkuwa za 100%, zomwe zimapereka ma conductivity abwino komanso moyo wautali. Kuphatikiza apo, kupewa kugwiritsa ntchito majekeseni a PoE kapena ma switch omwe sangathandizire kuperekera mphamvu moyenera ndikofunikira. Pakuchita bwino kwambiri, zingwe za Cat6 ndi njira yabwino kwambiri chifukwa cha zowongolera zamkuwa zokulirapo, zomwe zimathandizira kutulutsa kutentha komanso kuchita bwino kwa ntchito za PoE.

Mapeto

Pomaliza, Power over Ethernet (PoE) ndi njira yosinthira masewera yomwe imathandizira kutumiza magetsi ku zida zama netiweki pomwe ikupititsa patsogolo magwiridwe antchito ndi kuphatikiza mkati mwazinthu zomwe zilipo kale. Pomwe ukadaulo ukupitilirabe kusinthika, PoE ikadali yofunikira kwambiri pakupanga zida zamagetsi moyenera, zomwe zimathandizira kuti pakhale malo anzeru komanso olumikizidwa pamitundu yosiyanasiyana. Pomvetsetsa kuthekera kwake ndikugwiritsa ntchito njira zabwino kwambiri, ogwiritsa ntchito atha kupindula bwino ndiukadaulo wamakonowu.
