Nekukurumidza kusimudzira kwemafoni eIP, isina waya yeLAN yekuwana nzvimbo APs, uye network yekutarisa mumakore achangopfuura, iyo tekinoroji chikumbaridzo chiri kuramba chichikwira nekukwira, uye rutsigiro rwehunyanzvi rwunopihwa nevagadziri rwuri kuwedzera kuwanda uye kurongeka.Pakati pekutsinhana kwehunyanzvi, pakati peakanyanya kuvhiringidzika nemakambani einjiniya idambudziko rePOE magetsi ekupa.
Mubvunzo wekutanga: Chii chinonzi PoE tekinoroji?
PoE (Power Over Ethernet) inoreva kune iripo Ethernet Cat.5 cabling infrastructure pasina chero shanduko, kune dzimwe IP-based terminals (senge IP phones, wireless LAN access point AP, network cameras Etc.) Paunenge uchitumira data, inogonawo zvakare. kupa DC magetsi emagetsi tekinoroji yemidziyo yakadaro.PoE tekinoroji inogona kuvimbisa kuchengetedzeka kweiyo iripo yakagadziridzwa kabheti uku ichiona kushanda kwakajairwa kwetiweki iripo, ichidzikisa zvakanyanya mutengo.
Iyo yakakwana PoE system inosanganisira zvikamu zviviri: magetsi ekushandisa (PSE, Power Sourcing Equipment) uye magetsi ekugamuchira midziyo (PD, Powered Chidimbu).
Power Supply Equipment (PSE): Ethernet switch, routers, hubs, kana imwe network inoshandura michina inotsigira POE.
Simba rekugamuchira mudziyo (PD): Iyo isina waya yekuvhara purojekiti inonyanya kuve isina waya AP.
Mubvunzo 2: PoE magetsi emagetsi akagadzikana here?
Kubva pane tekinoroji yekuona, tekinoroji yePoE yakagadziridzwa nekufamba kwemakore uye iko zvino yave padanho rakakura kwazvo.Nekudaro, nekuda kwekudzvanywa kwemutengo wemusika wekutarisa, mhando yePoE switch kana tambo dzinoshandiswa dzakadzikira, kana dhizaini pachayo haina musoro, zvichikonzera basa rinorema remapurojekiti anoshandisa PoE magetsi.Maonero akatsiga.
Muchiitiko chekutumira data kukuru, simba guru, uye zvinodiwa zve 24/7 basa risina kukanganisa, kushandiswa kwemhando-yakavimbiswa yePoE michina uye waya ivimbiso yekugadzikana kwehurongwa hwose.
Mubvunzo 3: Ndeapi mabhenefiti ePoE magetsi ekugadzirisa?
1. Rerutsa wiring uye chengetedza mari yevashandi
Netiweki tambo inotumira data uye simba panguva imwe chete.PoE inobvisa kudiwa kwemagetsi anodhura uye nguva inotora kuisa magetsi, kuchengetedza mari uye nguva.
2. Yakachengeteka uye yakanakira
PoE magetsi ekushandisa anongopa simba kumidziyo inoda kuvezwa.Chete kana iyo michina inoda kuvezwa yakabatana, pachave nevoltage paEthernet tambo, nekudaro kubvisa njodzi yekudonha pamutsetse.Vashandisi vanogona kusanganisa zvakachengetedzeka zvishandiso zvepakutanga nePoE zvishandiso panetiweki, uye zvishandiso izvi zvinogona kugarisana netambo dzeEthernet dziripo.
3. Ita kuti utariri huri kure
Kufanana nekufambiswa kwedata, PoE inogona kutarisa nekudzora chishandiso nekushandisa Nyore Network Management Protocol (SNMP).Iri basa rinogona kupa mabasa akadai sekuvhara kwehusiku uye kureta restart.
Mubvunzo wechina: Ndedzipi njodzi kana kuipa kwePoE magetsi ekugadzira tekinoroji mumashandisirwo einjiniya?
1. Simba risina kukwana, simba rekugamuchira simba harigoni kutungamirirwa: 802.3af standard (PoE) simba rekubuda ndiro 15.4W.Kune yakakwirira-simba pamberi-yekupedzisira michina, iyo inobuda simba haigone kusangana nezvinodiwa.
2. Ngozi yakanyanyisa: Kazhinji kutaura, PoE switch ichapa simba kune akawanda maAP panguva imwe chete.Chero kutadza kwePOE simba rekupa module yekuchinja kuchaita kuti zvese zvishandiso zvitadze kushanda, uye njodzi yacho yakanyanyisa.
3. Zvishandiso zvepamusoro uye mari yekugadzirisa: Kana ichienzaniswa nedzimwe nzira dzekupa magetsi, teknolojia yePoE yemagetsi inowedzera basa rekugadzirisa mushure mekutengesa.Mupfungwa yekuchengeteka uye kugadzikana, kugadzikana uye kuchengeteka kwemagetsi akasiyana-siyana akanaka kwazvo.
Mubvunzo 5: Ungasarudza sei PoE switch?
1. Simba rakawanda sei rinodiwa kusimbisa michina: PoE switches inoshandisa zviyero zvakasiyana, uye simba rekubuda richave rakasiyana, semuenzaniso: IEEE802.3af haipfuuri 15.4W, nekuda kwekurasikirwa kwetambo dzekutumira, inogona kupa michina ne simba rekushandisa risingapfuure 12.95W powered by.PoE switch inoenderana neIEEE802.3at chiyero inogona kupa simba kumidziyo ine simba rekushandisa risingadarike 25W.
2. Ingani michina inogona kushandiswa: Chiratidzo chakakosha chePoE switches isimba rose rePoE simba rekupa.Pasi peIEEE802.3af chiyero, kana simba rose rePoE re24-port PoE switch rasvika 370W, rinobva rakwanisa kupa 24 ports (370 / 15.4 = 24), asi kana riri re-single-port power supply maererano neIEEE802. .3 pachiyero Simba rinoverengwa pa 30W, uye panguva imwe chete, rinogona kupa simba kune zviteshi zve 12 zvakanyanya (370/30 = 12).
3. Inoda huwandu hwemainterfaces, kungave kuunza fiber port, ine kana isina network manejimendi, kumhanya (10/100 / 1000M).
Mubvunzo wechitanhatu: Nzvimbo yekufambisa yakachengeteka yePoE magetsi?Ndeapi mazano ekusarudzwa kwetambo dzenetwork?
Iyo yakachengeteka yekufambisa kureba kwePOE magetsi ekupa 100 metres.Inokurudzirwa kushandisa marudzi ese mashanu etambo dzemhangura.
Iyo POE power supply network cable inoda kuti dambudziko iri rive dambudziko chete munyika dzakaita seChina nedzimwe nyika uko zvinhu zvemanyepo uye zvakachipa zvakatekeshera.Harisi dambudziko munyika dzakawanda dzakabudirira.Iyo POE IEEE 802.3af yakajairwa inoda kuti simba rekubuda rePSE inobuda chiteshi i15.4W kana 15.5W.Iyo PD mudziyo unogamuchira simba mushure mekufambisa 100 metres haufanirwe kunge uri pasi pe12.95W.Zvinoenderana ne802.3af yakajairika ikozvino kukosha kwe350ma, kushorwa kweiyo 100 metre network tambo inofanirwa Iko (15.4-12.95W) / 350ma = 7 ohms kana (15.5-12.95) / 350ma = 7.29 ohms.
Iyo yakajairwa netiweki tambo inowanzosangana nezvinodiwa izvi.Iyo IEEE 802.3af poe simba rekupa mwero pachayo inoyerwa neyakajairwa network tambo.Chikonzero nei POE magetsi ekupa network tambo dzinodiwa imhaka yekuti tambo zhinji dzenetiweki pamusika hadzisi-yakajairwa network tambo, dzisina kugadzirwa zvakanyatsoenderana nezvinodiwa zveyakajairwa network tambo.Zvishandiso zveasina-standard network tambo pamusika zvinonyanya zvinosanganisira simbi yemhangura, copper-clad aluminium, uye mhangura-yakapfeka simbi.Aya matambo etiweki ane hukuru hwekupokana uye haana kukodzera kuPOE magetsi ekupa.POE magetsi anofanirwa kushandisa oxygen-isina copper network tambo, kureva, yakajairwa network tambo.
