PoE chinjainoreva switch inogona kupa network simba rekupa kune kure kure powered terminals kuburikidza netiweki tambo. Icho chinhu chinowanzojairika magetsi ekushandisa muPoE magetsi emagetsi masisitimu. Nekudaro, kana switch isina POE basa, imwe poe magetsi ekuwedzera module inogona kuwedzerwa kusimba iyo AP kuburikidza nekuchinja? Kutaura zvazviri, zvinobvira. Inogona kungoonekwa sekushandisa isingaite 4578 tsoka dzetiweki tambo mune 100M network nharaunda kuendesa simba. Iko ndiko kubatanidza musanganiswa wePOE (inozivikanwawo sePOE simba rekupa) pakati pekuchinja neAP, asi chimiro chinoenderana nekuti AP yako inotsigira kugamuchira POE magetsi.

PoE chinja simba rekupa modhi imwe

Saka kana iwe uine sirin'i-yakaiswa isina waya AP, mazhinji acho anoitsigira. Imwe magumo itambo yetiweki kubva kunetiweki chiteshi, uye imwe magumo itambo yetiweki uye DC plug, iyo inobairwa mu AP's network port uye power port. Ndizvo. Nekudaro, mune iyi kesi, pane nzira mbiri dzekushandisa POE kupa simba kuAP, asi imwe yekuwedzera 48V kusvika 12V POE splitter inowedzerwa kuAP.

Iri rudzi rwePOE splitter ichokwadi DC48V kusvika 12V transformer. Imwe magumo itambo yetiweki kubva kunetiweki port kuti ibaire muPOE, uye imwe magumo inetiweki tambo musoro uye DC simba plug, iyo inobairwa mu AP's network port uye power port.

PoE chinja magetsi ekupa maitiro maviri

Imwe magumo ndeyetiweki tambo plug, iyo inoiswa mukati metiweki madziro plug inotungamira kune AP. Iyo yakafanana neiyo iri munzira yekutanga. Kana bhuku racho rikasanyora kutsigira POE, kazhinji haritsigirwi, nekuti kuwedzera chikamu ichi chedunhu kunoda makumi eyuan. Mutengo. Batanidza tambo yetiweki kubva pachinja uye 12V simba adapta muAP yako, asi hapana chikamu chekushandura; iyo DATA yekubatanidza inogona kubatana neAP. Kana ichitsigirwa, 48V POE magetsi ekupa module inogona kubatanidzwa pakati pekuchinja uye AP. Kune maviri network ports paPOE power supply module, uye switch yakabatana neDATA yakanyorwa. Chiteshi cheDATA chakabairirwa mutambo yetiweki kubva kuchinochinja, uye DATA&POWER chiteshi chinobairirwa mutambo yetiweki inoenda kuAP. Zvadaro tambo yetiweki pamagumo eAP inobatanidzwa kune POE splitter kana splitter, iyo inotsigirwawo, asi simba rekushandisa rakagadzikana uye urefu hwetambo yetambo inobvumirwa kusvika mamita zana kana kupfuura. Iyi nzira ine mutengo wakaderera, asi kana mhando yetambo yetiweki yakashata kana kureba, inokonzeresa kusakwana kwemagetsi kuAP.

Mazano ePOE switch

Nzira yekutanga inodhura uye inoda kuti AP itsigire Poe magetsi. Kana iwe usingaitsigire, haugone kushandisa iyi nzira yekubatanidza. Zvikasadaro, zvakanaka kana yakashongedzerwa neotomatiki yekuona mudziyo wekugamuchira magetsi. Kana iyo POE module ikamanikidzwa kupa simba, ichapisa AP. Kazhinji, musanganisi akareruka pamusika ndiye ane mugumo mumwe. Imwe network port uye imwe DC yechikadzi yekubatanidza. Kunyangwe iyo inotsigira bhuku racho ichanyorwa (kana bvunza mutengesi), semuenzaniso, zvakanyorwa kuti inotsigira IEEE 802.

Iyo DC yechikadzi chiteshi pane musanganisi inobatanidzwa mune simba adapta yeAP, uye inokodzera chete 100M network nharaunda. Kana yakabatana muGigabit network, ichapisa mudziyo. Iyi nzira haisi yechikamu cheiyo POE yakajairwa. Kana iwe ukasaivhara nepamadziro, iwe unofanirwa kutenga iyo mhando ye modular musanganisi. Vamwe vagadziri vachave vane usimbe uye vanongonyora kuti vanotsigira POE magetsi. 3af kana IEEE 802.3at, zvinoreva kuti vanoitsigira.
