Izinzuzo zokuphepha zokushintshwa kwe-PoE

① Iswishi ye-PoE ingaxazulula izinkinga zomjikelezo omfushane, ukugcwala ngokweqile, ukushintsha kwamandla kagesi, njll., futhi inganikeza ukuvikeleka okuhle kokunikezwa kwamandla.

②Iswishi evamile ye-PoE izohlinzeka ngomshini wokugcina amandla okubona i-voltage ephansi ukuze isekele idivayisi ye-PoE ngaphambi kokunikezwa kwamandla.Uma kungenjalo, khona-ke akukho ukunikezwa kwamandla, uma yebo, kancane kancane ukwandisa i-voltage ukuqedela ukunikezwa kwamandla, ngakho-ke uxhumano oluphephile nokusebenza kwesistimu yenethiwekhi kungaqinisekiswa.

③Ukushintsha kwe-PoE kungathuthukisa ukutholakala kwezinhlelo zokusebenza zebhizinisi ezibalulekile, kunikeze ukuvikeleka kwezinga lesisetshenziswa esithuthukisiwe, nokuvikela ulwazi olubucayi.Lungiselela umkhawulokudonsa wenethiwekhi futhi unikeze ingqalasizinda ethembekile yamanethiwekhi ebhizinisi labasebenzisi.

Isixazululo sokuxhuma se-PoE:

Isistimu yokushintsha ye-PoE ephelele ihlanganisa izingxenye ezimbili: okokusebenza kwamandla kagesi (PSE, Power Sourcing Equipment) kanye nemishini yokwamukela amandla (PD, PowerDevice).Iswishi ye-PoE iwuhlobo lwedivayisi ye-PSE.Idivayisi ye-PSE iyisisetshenziswa esinikeza amandla kudivayisi yeklayenti le-Ethernet futhi futhi ingumphathi wayo yonke inqubo yokuphakelwa kukagesi ye-PoE Ethernet.Idivayisi ye-PD ingumthwalo we-PSE owamukela ukunikezwa kwamandla, okungukuthi, iklayenti lohlelo lwe-PoE.

Kafushane, ukushintsha kwe-PoE kungaqinisekisa ukuphepha kwenethiwekhi.Uma ufuna ukuqinisekisa ukuxhumana okuzinzile kwamaswishi e-PoE, udinga ukucabangela ezinye zezinto ezingenhla.
