Simba pamusoro peEthernet (POE)tekinoroji yakashandura mabatiro atinoita midziyo yedu, ichipa nyore, kushanda nesimba uye kuchengetedza mutengo.Nekubatanidza simba uye kutumira data patambo yeEthernet, POE inobvisa kudiwa kwetambo yemagetsi yakasiyana, ichiita kuti ive yakakodzera kune zvakasiyana-siyana zvekushandisa zvakadai se IP kamera, wireless access points, uye VoIP mafoni.Nekudaro, usati wadyara mune chero network mhinduro, zvakakosha kuti unzwisise mutsauko uripo pakati peyakajairwa uye isiri-yakajairwa POE switch.

Standard POE switches inotevera Institute of Electrical and Electronics Engineers (IEEE) 802.3af kana 802.3at zviyero.Aya maindasitiri-anocherechedzwa mwero anotsanangura iyo yakanyanya simba kubuda iyo switch inogona kuendesa kune POE-inoenderana zvishandiso.Iyo inonyanya kushandiswa magetsi mune yakajairwa POE switches ndeye 48V.

Kune rimwe divi, zvisiri-yakajairwa POE switch inogona kusatevedzera aya maIEEE zviyero.Vanowanzo shandisa maitiro evaridzi anotsauka kubva pane zvakatarwa tsika.Nepo ma switch aya angaite senge sarudzo inogoneka nekuda kwekugona kuderera mutengo, ivo vanoshaya kudyidzana uye kuvimbika kweyakajairwa POE switch.Zvakakosha kunzwisisa mutsauko pakati pezviviri uye njodzi dzinogona kuitika dzine chekuita neasina mweroPOE inochinja.

Musiyano mumwe wakakosha pakati peyakajairwa uye isiri-yakajairwa POE switch ndiyo voltage yavanopa kumidziyo yakabatana.StandardPOE inochinjakushanda pa 48V simba.Idzi sarudzo dzinogamuchirwa zvakanyanya uye dzinotsigirwa nemidziyo yakawanda inogonesa POE pamusika.Vanopa simba rakavimbika, rakagadzikana, kuve nechokwadi chekushanda kusina musono uye kushanda kwakakwana.

Kusiyana neizvi, masiwichi asiri akajairwa ePOE anoshandisa sarudzo dzemagetsi kunze kwe48V.Nepo mamwe eaya ma switch achipa epamusoro masimba ekuunza masimba, iwo anoshaya kuenderana neyakajairwa POE zvishandiso.Kusapindirana uku kunogona kukonzera nyaya dzakasiyana siyana, kusanganisira kushaikwa kwesimba, kuderedzwa kwechishandiso, uye kunyangwe kukuvara kungangoitika kumidziyo yakabatana.

Kuti usiyanise pakati peyakajairwa uye isiri-yakajairwa POE switch, tanga nekutarisa magadzirirwo emagetsi anopihwa neanogadzira switch.Maswichi anowirirana anozoratidza zvakajeka kana ari kuenderana neIEEE 802.3af kana 802.3at chiyero, pamwe nesarudzo dzemagetsi dzavanotsigira.Aya maswichi anozotaura yakakwira simba rekubuda pachiteshi chega chega, kuve nechokwadi kuti unogona kuchengetedza POE zvishandiso.

Nekune rimwe divi, zvisiri-yakajairwa POE switching inogona kusateedzera kune aya akanyatsotsanangurwa zviyero.Ivo vanogona kupa yakakwira simba kubuda kana kushandisa isiri-standard voltage sarudzo, senge 12V kana 56V.Ngwarira kana uchifunga nezverudzi urwu rwekuchinja sezvo vangave vasingape mazinga emagetsi anodiwa nemudziyo wako kana kuti anogona kukonzera kuti mudziyo ukunde nguva isati yakwana.

Imwe nzira yekusiyanisa pakati peyakajairwa uye isiri-yakajairwa POE switch ndeyekuvimba nevane mukurumbira network vagadziri vemidziyo.Vagadziri vakagadzirwa vanogadzira yakavimbika uye yakamisikidzwa POE switch inoteerana neindasitiri zvakatemwa.Ivo vanopinda mukuyedzwa kwakasimba kuti vasangane nemhando yepamusoro uye kuendesa hukuru hwekuita.

Paunenge uchida maPOE switch, unogona kutibata chero nguva.Kambani yedu,JHA Tech, yave ichitarisa paR & D, kugadzirwa uye kutengesa kwekuchinja kwakasiyana-siyana kubvira 2007. Haisi chete ine mukana wakakura kwazvo mumutengo, asiwo inovimbiswa zvikuru muhutano nokuti takawana zvitupa zveunyanzvi uye zvine chiremera;
