A PoE switch is switch inotsigira magetsi kune network tambo. Kana ichienzaniswa neakajairika switch, iyo yekugamuchira magetsi terminal (yakadai seAP, digital kamera, nezvimwewo) haidi kuvharwa newaya yemagetsi, inovimbika kune network yese.Nhoroondo ye JHA Technologyichaunza tekinoroji uye zvakanakira zvePOE switch mune zvakadzama pano.

Musiyano uripo pakati pePoE switch uye zvakajairwa switch

Iyo PoE switch haingogone kupa basa rekutapurirana reyakajairwa switch, asi zvakare inopa simba rekupa basa kune imwe magumo etiweki tambo. Semuenzaniso, kune dhijitari yekutarisa kamera (inoda magetsi kuti ishande zvakajairika), asi haina kubatana kune simba sosi, asi yakabatana kune yakajairwa switch kuburikidza netiweki tambo. Muchiitiko ichi, kamera haishande. Kana iyo kamera isina kubatana kune magetsi, asi yayo yekufambisa network tambo yakabatana nePoE switch, kamera inogona kushanda zvakajairika.

PoE yakakamurwa kuva yakajairwa uye isiri-yakajairwa. Iyo yakajairwa ichaona kana iyo yakabatana network mudziyo ine PoE yekugamuchira simba yekupedzisira. Kana iripo, ichave inofambiswa, kana isiri, haizove nemagetsi uye inopa chete kutapurirana data. Kana isiri chiyero, ichapa simba zvakananga. Kana iyi link ikasaonekwa, mudziyo unogona kupiswa.

POE chinja tekinoroji uye zvakanakira

Pane zviyero zviviri zvemainstream PoE switch pamusika, IEEE802.3af uye 802.3 pa, iyo inotsanangudza simba rekupa simba re15.4W uye 30W, asi nekuda kwekurasikirwa kweiyo nzira yekufambisa, iyo chaiyo magetsi i12.95W uye 25.5W, rated voltage Ndiyo DC 48v. Paunenge uchishandisa PoE switch inotsigira IEEE802.3af chiyero, simba remuchina wemagetsi haugone kudarika 12.95W; zvakafanana, kana uchishandisa PoE switch yeIEEE802.3at chiyero, simba reiyo powered device haigoni kudarika 25.5W.

Kazhinji, poE switch inotsigira IEEE802.3af/pachiyero panguva imwe chete, simba rekushandisa rinogadziriswa. Semuenzaniso, kana yakabatana kune 5W mudziyo, inopa 5W yesimba; kana yakabatanidzwa kune 20W mudziyo, inopa 20W yesimba.A PoE switch is switch inotsigira magetsi kune network network. Zvichienzaniswa neakajairika switch, materminals (akadai seAPs, digitaalinen makamera, nezvimwewo) haafanire kuve newaya yekugovera magetsi, ayo anonyanya kuvimbika kune network yese. Iyo PoE switch haingogone kupa basa rekutapurirana reyakajairwa switch, asi zvakare inopa simba rekupa basa kune imwe magumo etiweki tambo. Iyo PoE yekumashure-yekupedzisira mudziyo inongoda imwe tambo yetiweki, inochengetedza nzvimbo, inogona kufambiswa pakuda (nyore uye nyore), uye inochengetedza mutengo.

Chero bedzi iyo PoE switch yakabatana neUPS, inogona kupa simba kune ese kumashure-kumagumo ane hukama nePOE kana simba radzimwa. Vashandisi vanogona kusanganisa otomatiki uye zvakachengeteka michina yepakutanga nePoE midziyo panetiweki, uye michina iyi inogona kugarisana netambo dzeEthernet dziripo.
