Simba pamusoro peEthernet (PoE) teknolojia inoita kuti shanduro dzeEthernet dzese dzese dzinoshanda semashonga emasimba. Mune hutano hwePoE-enabled, inotungamirira magetsi (DC) inotenderera pamusoro pekambani yenethiwekhi pamwe chete nehutachiona hwemashoko eEthernet. Zvizhinji zvePoE zvishandise zvinotevera IEEE yepamusoro 802.3af kana 802.3at .
Simba pamusoro peEthernet rakagadzirirwa kushandiswa nemichina yakagadzirwa nemasikironi uye isina mashizha e -Wi-Fi access points (APs) , webcams, uye mafoni VoIP . PoE inobvumira mapuraneti ekugadziriswa kuti ave akaiswa munzvimbo dzekufambisa kana nzvimbo dzorusvingo apo magetsi magetsi haasi nyore kusvika.
Inyanzvi yekombiyuta isingaenderani nePoE, Ethernet pamusoro pemagetsi emagetsi inoita kuti magetsi emagetsi ega ega agone kuita sendima yakakura Ethernet network links.
Chinoita Kuti Mikana Yakawanda Yese Makombiyuta Asapindire Ethernet
Nemhaka yokuti dzimba dzinowanzova nemagetsi akawanda uye zvishoma shoma Ethernet rusvingo jacks, uye vazhinji magadhi anoshandiswa vanoshandisa Wi-Fi kuwirirana panzvimbo yeEthernet, zvishandiso zvePoE zvekutengesa musha zvishoma. Vatengesi veNetanda vanowanzobatanidza kutsigirwa kwePoE pamagetsi avo ekupedzisira uye mabhizinesi uye mabhizimusi emagetsi nekuda kwechikonzero ichi.
DIY vashandi vanogona kuwedzera PoE kutsigirwa kune imwe sangano reEthernet vachishandisa chidimbu chiduku uye chakashata chinonzi PoE injector. Izvi zvinosanganisira ports Ethernet (uye adapta yemagetsi) iyo inobvumira cables ethernet yakazara nesimba.
Ndezvipi Zvimwe Zvishandiso Zvinoshanda Nesimba Pamusoro peEthernet?
Kuwanda kwesimba (mu watts) inogona kugoverwa pamusoro peEthernet kunogadziriswa nehutaneti. Icho chikonzero chemasimba chinodikanwa chinoenderana neanotaridzirwa mvura yePoE source uye simba rekushandisa kwevashandi vechikwereti. IEEE 802.3af, somuenzaniso, inogonesa 12.95W chete emasimba pane humwe hutano. Desktop PC ne laptops kazhinji hazvikwanisi kushanda paPeE nekuda kwezvavanoda zvepamusoro (zvinowanzoita 15W uye kumusoro), asi zvigadzirwa zvinotakura se webcams zvinoshanda pasi pe10W zvinogona. Bhizinesi mitambo dzimwe nguva inosanganisira kuchinja kwePoE kuburikidza neboka re webcams kana zviyero zvakafanana zvinoshanda.
