Uma ukunikezwa kukagesi kwe-PoE kwehluleka, kungaphenywa ngezici ezine ezilandelayo.
• Hlola ukuthi idivayisi yokugcina eyamukelayo iyakusekela yini ukunikezwa kwamandla kwe-PoE. Njengoba kungewona wonke amadivaysi enethiwekhi angasekela ubuchwepheshe bamandla e-PoE, hlola okokusebenza kobuchwepheshe bamandla e-POE ngaphambi kokuyixhuma ku-PoE.shintsha. Nakuba i-PoE izotholwa uma isebenza, ingakwazi ukubona kuphela futhi inike amandla idivayisi eyamukelayo esekela ubuchwepheshe bokuphakelwa kwamandla we-POE. Uma i-PoEshintshaayinikezi amandla, kungase kube ngenxa yokuthi idivayisi eyamukelayo ayikwazi ukusekela ubuchwepheshe bokunikezwa kwamandla we-PoE.
• Hlola ukuthi amandla edivayisi eyamukelayo ayadlula amandla amakhulu we-shintshaichweba. Isibonelo, i-POEshintshaesekela kuphela izinga le-IEEE 802.3af (amandla aphezulu wembobo ngayinye ku-shintshaingu-15.4W) ixhunywe kudivayisi yokwamukela amandla engu-16W noma ngaphezulu, futhi idivayisi eyamukelayo ingase yonakalise okokusebenza ngenxa yokwehluleka kwamandla noma ukungazinzi kwamandla, okuholela ekuhlulekeni kwamandla kanye nokuhluleka kokunikezwa kwe-PoE.
• Hlola ukuthi amandla aphelele awo wonke amadivayisi axhunyiwe amukelayo ayasidlula isabelomali samandla se-shintsha. Lapho amandla aphelele wezinto ezixhunyiwe edlula isabelomali samandla weshintsha, ukunikezwa kwamandla kwe-PoE kuzohluleka.ngokwesibonelo, i-A 24-port PoEshintshangesabelomali samandla esingu-370W, Uma ishintshailandela izinga le-IEEE 802.3af, Ingaxhunywa kumadivayisi amukelayo angu-24 alandela izinga elifanayo (ngoba amandla alolu hlobo lwesisetshenziswa ngu-15.4W, Xhuma okokusebenza okungu-24 ngamandla aphelele angu-369.6W, Angeqishintshaisabelomali samandla); Uma ishintshailandela i-IEEE802.3at evamile, Amadivayisi angu-12 kuphela atholayo alandela izinga elifanayo (njengoba amandla alolu hlobo angu-30W, Ukuxhuma kumayunithi angu-24 kuzodlula isabelomali samandlashintsha, Ngakho-ke, amayunithi ayi-12 kuphela angaxhunywa).
• Hlola ukuthi ingabe imodi yokunikeza amandla yedivayisi eyamukelayo (PSE) iyahambisana yini nedivayisi eyamukelayo (PD). Isibonelo, i-PoEshintshaisebenzisa imodi A, kuyilapho idivayisi eyamukelayo exhunyiwe ingathola kuphela ukudluliswa kwamandla kumodi B, engeke ibe namandla.
Ukungaphumeleli kokunikezwa kwamandla kwe-PoE kokuthi ungahlolwa kanjani kucishe kube ngaphezu kwezinyathelo ezimbalwa, mayelana nalokhu okungenhlashintshaimikhiqizo yochungechunge e-Shenzhen sea DiWei photoelectric technology co., LTD ingeyesigaba semikhiqizo yokuxhumana, efana ne: Ethernetshintsha, i-fiber opticalshintsha, i-ethernet fibershintsha, njll., okungenhlashintshaingasetshenziswa kuzo zonke izinhlobo zezimo, inikeze abasebenzisi ukukhetha okwengeziwe ngezidingo ezahlukene, siyakwamukela ukuyiqonda, mayelana nesevisi yangaphambi kokuthengisa kanye neyokuthengisa ngemva kokuthengisa, sineqembu lesevisi elichwepheshile, elingahlinzeka amakhasimende ngesevisi yekhwalithi ephezulu.
