Kuchinja kunowanzoshandiswa mumapurojekiti asina simba, kunyanyaPOE inochinja.POE inodaidzwa zvakare kuti inzvimbo yenzvimbo network-based power supply system (POL, Simba pamusoro peLAN) kana Active Ethernet (Active Ethernet), dzimwe nguva inonzi Simba pamusoro peEthernet.Iyi ndiyo yazvino yakajairwa dhizaini yekufambisa panguva imwe chete data uye simba remagetsi uchishandisa aripo akajairwa Ethernet tambo dzekutumira, uye inochengetedza kuenderana nearipo Ethernet masisitimu nevashandisi.Saka, isu tinosarudza sei switch yePOE?

1. Funga nezvesimba remidziyo yako

Saizvozvo sarudza PoE switch ine simba repamusoro.Kana simba remudziyo wako riri pasi pe15W, wobva wasarudza poE switch inotsigira 802.3af standard.Kana simba racho rakakura kudarika 15W, sarudza switch-power switch ine 802.3at standard.Parizvino, maPoE switch mazhinji anotsigira af uye at, saka teerera zvakanyanya paunenge uchitenga.

2. Chiteshi chenyama

Chekutanga pane zvese, zvinodikanwa kuona huwandu hwema switch interfaces, nhamba ye optical fiber ports, network manejimendi, kumhanya (10/100/1000M) nezvimwe nyaya.Parizvino, nzvimbo dzekutarisana pamusika dzinonyanya 8, 12, 16, uye 24 ports.Kune kazhinji imwe kana maviri optical fiber ports, uye iwe unofanirwa kutarisisa kuti optical port iri 100M kana 1000M.Zvinoenderana nemamiriro ezvinhu.

PoE switch anowanzo shandiswa kubatanidza materminals ane powered uye anoshandiswa sekuchinja kwekuwana.Funga nezvehuwandu hwePoE magetsi ekupa zviteshi zvinotsigirwa ne switch zvinoenderana nehuwandu hwemagetsi emagetsi terminal.Pamusoro pezvo, zvinodikanwawo kufunga nezvehuwandu hwepamusoro hunodiwa nechiteshi kutsigira zvinoenderana neiyo powered terminal uye izvo chaizvo zvinodiwa.Semuenzaniso, kana chiteshi che AP chiri Gigabit uye chichishandisa 11AC kana mbiri-bhendi, Gigabit kuwana inogona kutariswa.

3. Simba rekupa parameters

Sarudza chinja chakakodzera maererano nemagetsi ekupa protocol (yakadai se802.3af, 802.3at kana isiri-standard PoE) inotsigirwa neiyo powered terminal (AP kana IP kamera).Iyo PoE magetsi ekupa protocol inotsigirwa ne switch inofanirwa kuenderana neiyo powered terminal.Kune dzakawanda dzinogona kuitika njodzi dzekuchengetedza mune dzisiri-yakajairwa PoE switch.Zvinokurudzirwa kuti uedze kusarudza yakajairwa 48V PoE switch zvishandiso.

4. Wiring scheme

Vashandisi vanogona kuenzanisa uye kuverenga mutengo weiyo terminal's emunharaunda magetsi emagetsi wiring uye mutengo wekushandisa PoE switch yemagetsi.Parizvino, chinhambwe chekupa magetsi chePoE switch chiri mukati me100 metres.Iko hakuna zvirambidzo zvekugadzirisa, izvo zvinogona kuchengetedza nezve 50% yemutengo wakazara.Wiring mukati me100 metres inogona kuchinjika kuwedzera network pasina kudziviswa nekurongeka kwetambo dzemagetsi.Hang wireless APs, makamera etiweki uye zvimwe zvigadziriso zvemagetsi pamadziro akareba kana sirin'i kuti iwedzere kuchinjika, wiring iri nyore, uye kutaridzika kwakanaka.

5. Pre-sales uye mushure mekutengesa-technical support

Sarudza vatengesi vanovimbika kuti uwane nyanzvi dzekutanga-kutengesa uye mushure mekutengesa masevhisi
