Nekuenderera mberi kwekuvandudza tekinoroji yePoE, maPoE switch parizvino ari padanho rakakura kwazvo, zvisinei, nekuda kwemusika wazvino wekutarisa pasi pekumanikidzwa kwemutengo, mhando yeakasarudzwa PoE switch kana tambo yakadzikira, kana chirongwa dhizaini pachacho. hazvina musoro, izvo zvinozoita kuti pave nebasa rinorema rekuchengetedza mapurojekiti emagetsi ePoE. Iyo network yekutarisa purojekiti yakasiyana neyakajairwa network yakasanganiswa wiring, vhoriyamu yekufambisa data yakakwira, simba rakakwira, uye rinoda basa risingapindirwe nguva nenguva, saka maonero ekuti PoE magetsi haana kugadzikana. Asi magetsi ePOE haana kunyatsogadzikana here? Ngatizivise kuti PoE switch inogona kubatanidzwa zvakadzikama sei uye ndedzipi zvakanakira kuchengetedza kwePoE switch? Ngatitarisei!

Nzira yekuita sei yakagadzikana kubatana kwePoE switch?

① Shandisa yakajairwa PoE switch. Non-standard PoE switches haina IEEE802.3af kana IEEE802.3at maprotocol. Pasinei nekuti iyo terminal mudziyo inotsigira PoE magetsi, kumanikidza 48V kubuda magetsi kunokuvadza mudziyo wekupedzisira. Naizvozvo, kushandiswa kweakajairwa PoE switch yekubatanidza ndiyo nhanho yekutanga kuona kugadzikana kushanda kwetiweki system.

②Shandisa chigamba chine tambo.Dzivisa kutenga tambo dzechigamba dzisiri dzemhando yepamusoro dzemhando isina kukodzera. Nekuda kwekuti ivo havana kugadzirwa zvakanyatsoenderana nezvinodiwa zveyakajairwa network cables, copper-clad simbi / aluminium / simbi inogona kuitika. Naizvozvo, kushorwa kwetambo yetiweki kuchave kwakakura uye haina kukodzera PoE magetsi ekupa.

③Sarudza mashandisirwo emagetsi emagetsi ekupedzisira. Kusiyana kwePoE switches zviyero zvine masimba akasiyana ekubuda, akadai se: IEEE802.3af yakajairwa POE switch inogona kupa simba kumidziyo ine simba guru rekushandisa risingapfuuri 15.4W; Iyo PoE switch inoenderana neIEEE802.3at chiyero inogona kupa simba kumidziyo ine simba guru rekushandisa risingapfuuri 30W. Zvinoenderana nedanho rekutapurirana uye kurasikirwa kwezvinhu, iyo yakanyanya kushandiswa simba inogona kupihwa inogona kunge yakaderera.

④Bvisa nhamba yemidziyo yekushandisa. Pasi peIEEE802.3af chiyero, kana iyo yakazara PoE magetsi e24-port PoE switch inosvika 370W, inogona kupa 24 ports (370/15.4 = 24),; Asi kana ikaverengerwa maererano neIEEE802.3at chiyero cheimwe-chiteshi chepamusoro simba rekupa 30W, panguva imwe chete, inogona chete kupa simba kumachiteshi gumi nemaviri zvakanyanya (370/30=12).

⑤ Sarudza kureba kwekutapurirana. Iyo magetsi emagetsi kureba kwePoE switch inotarwa nekufamba kureba kwechiratidzo chedata. Kana chiyero chekufambisa chiri 100Mbps, kureba kureba iyo chiratidzo chedata chinogona kufambiswa i100m. Naizvozvo, kutonga chinhambwe chekufambisa zvichibva pachiyero chekutapurirana ndicho chimwe chezvinhu zvinopa kugadzikana kwekubatana kwePoE switch.

⑥Ine IETF RFC2544 yakajairwa. Iyi chiyero inogona kupa sevhisi yekuvhiringidza bhenji bvunzo nzira yekuyedza kubuda kwetiweki yekubatanidza michina, nhamba yekudzokera-kumashure-mafuremu, kurasika kwepaketi uye kunonoka kuita, uye kutarisa kugadzikana kwekubatana kwePoE switch.
