Izibonelelo zokhuseleko zokutshintsha kwe-PoE

① Iswitshi ye-PoE inokusombulula iingxaki zesekethe emfutshane, ukugcwala okugqithisileyo, ukutshintsha kwamandla ombane, njl. njl., kwaye inokubonelela ngokhuseleko lombane olungileyo.

②Ukutshintsha okusemgangathweni kwe-PoE kuya kubonelela ngesixhobo sokubona i-terminal esine-voltage ephantsi ukuxhasa isixhobo se-PoE phambi kokunikezelwa kombane.Ukuba akunjalo, ke akukho unikezelo lwamandla, ukuba ewe, ngokuthe ngcembe ukwandisa umbane ukugqiba unikezelo lwamandla, ngoko uqhagamshelwano olukhuselekileyo kunye nokusebenza kwenkqubo yenethiwekhi inokuqinisekiswa.

③Ukutshintsha kwePoE kunokuphucula ukufumaneka kwezicelo eziphambili zeshishini, ukubonelela ngezixhobo zokhuseleko olukwinqanaba eliphezulu, kunye nokukhusela ulwazi olubuthathaka.Yandisa i-bandwidth yenethiwekhi kunye nokubonelela ngeziseko ezithembekileyo zothungelwano lweshishini labasebenzisi.

Isisombululo sokudibanisa se-PoE:

Inkqubo yokutshintsha kwe-PoE epheleleyo iquka iinxalenye ezimbini: izixhobo zokubonelela umbane (i-PSE, i-Power Sourcing Equipment) kunye nezixhobo zokufumana amandla (PD, PowerDevice) .Ukutshintsha kwePoE luhlobo lwesixhobo se-PSE.Isixhobo se-PSE sisixhobo esinika amandla kwisixhobo somxhasi we-Ethernet kwaye ikwangumphathi wayo yonke inkqubo yonikezelo lwamandla e-PoE Ethernet.Isixhobo sePD ngumthwalo wePSE owamkela unikezelo lwamandla, oko kukuthi, umxhasi wenkqubo yePoE.

Isishwankathelo, iiswitshi ze-PoE zinokuqinisekisa ukhuseleko lwenethiwekhi.Ukuba ufuna ukuqinisekisa uqhagamshelo oluzinzileyo lokutshintsha kwe-PoE, kufuneka uqwalasele ezinye zezi zinto zingentla.
