PoE chinjachinhu chinoshandiswa zvakanyanya muindasitiri yekuchengetedza nhasi, nekuti inochinja inopa simba uye data kutapurirana kune kure switch (senge IP mafoni kana makamera), uye inoita basa rakakosha.Paunenge uchishandisa PoE switch, mamwe maPoE switch anoiswa chiratidzo chePoE, uye mamwe akanyorwa nePoE+.Saka, ndeupi musiyano uripo pakati pePoE switch nePoE +?

1. Chii chinonzi PoE switch

PoE switch inotsanangurwa neIEEE 802.3af standard uye inogona kupa kusvika ku15.4W yeDC simba pachiteshi.

2. Sei uchishandisa PoE switch

Mumakumi mashoma emakore apfuura, zvaive zvakajairika kuti mabhizinesi aise maviri akaparadzana mawaya network, imwe yesimba uye imwe yedata.Zvisinei, izvi zvakawedzera kuoma kwekugadzirisa.Kugadzirisa izvi, kuiswa kwePoE switch.Nekudaro, sekuda kwesimba kweakaomesesa uye epamberi masisitimu akadai seIP network, VoIP, uye yekutarisa shanduko, PoE switch yave chikamu chakakosha chemabhizinesi nenzvimbo dzedata.

3. Chii chinonzi POE+ chinja

Nekuvandudzwa kwehunyanzvi hwePoE, chiyero chitsva cheIEEE 802.3at chinobuda, chinodaidzwa kuti PoE+, uye ma switch anoenderana nechiyero ichi anonziwo PoE+ switch.Musiyano mukuru uripo pakati pe802.3af (PoE) ne802.3at (PoE+) ndewekuti PoE+ magetsi ekushandisa anopa simba rakapetwa kaviri semidziyo yePoE, zvinoreva kuti mafoni eVoIP anowanzo shandiswa, WAP uye IP cameras anomhanya paPoE+ ports.

4. Sei uchida POE+ switch?

Nekuwedzera kuri kuda kwesimba repamusoro PoE switch mumabhizinesi, zvishandiso zvakaita semafoni eVoIP, nzvimbo dzekuwana dzeWLAN, makamera etiweki nemimwe michina inoda ma switch matsva ane simba repamusoro rekutsigira, saka kudiwa uku kwakatungamira zvakananga kuzvarwa kwePoE + switch.

5. Zvakanakira zvePoE + switch

a.Simba repamusoro: PoE + switch inogona kupa kusvika ku30W yemagetsi pachiteshi, nepo PoE switch ichikwanisa kupa kusvika ku15.4W yesimba pachiteshi.Simba shoma rinowanikwa pamudziyo une powered wePoE switch i12.95W pachiteshi, ukuwo simba shoma riripo rePoE+ switch i25.5W pachiteshi.

b.Kuenderana kwakasimba: PoE nePoE + switch inogovera mazinga kubva 0-4 zvichienderana nehukuru hwesimba rinodiwa, uye kana mudziyo wemagetsi wakabatana kune mudziyo wemagetsi, inopa kirasi yayo kune yemagetsi mudziyo wemagetsi kuitira kuti magetsi ekushandisa. inogona kukupa huwandu hwakakodzera hwesimba .Layer 1, Layer 2, uye Layer 3 zvishandiso zvinoda yakaderera, yakaderera, uye ine mwero mashandisiro emagetsi, zvichiteerana, nepo Layer 4 (PoE +) switch inoda simba rakawanda uye inongoenderana chete nePoE + magetsi.

c.Kumwe kudzikisa mutengo: Iyi iri nyore PoE+ inoshandisa yakajairwa cabling (Katsi 5) kushanda neyakajairwa Ethernet interfaces, saka hapana "waya nyowani" inodiwa.Izvi zvinoreva kuti iripo network cabling infrastructure inogona kukwidziridzwa pasina chikonzero chekumhanya yakakwira-voltage AC simba kana kupatsanura magetsi ekubatanidza kune yega yega yakamisikidzwa switch.

d.Yakanyanya kusimba: PoE + inoshandisa chete CAT5 network tambo (iyo ine 8 waya dzemukati, zvichienzaniswa ne4 waya dzeCAT3), iyo inoderedza mukana weiyo impedance uye inoderedza kushandiswa kwesimba.Pamusoro pezvo, PoE + inobvumira vatariri venetiweki kuti vape hukuru hukuru, sekupa hutsva hwekuremerwa simba rekuongorora, mamiriro ekuzivisa, uye magetsi emagetsi manejimendi (kusanganisira kure kure bhasikoro remagetsi embedded switches).

Mukupedzisa, PoE switch uye PoE + switching inogona kugonesa network switch senge network kamera, APs, uye IP mafoni, uye ine yakanyanya kuchinjika, kugadzikana kwepamusoro, uye kusadzivirirwa kwepamusoro kukanganiswa kwemagetsi.
