Mphamvu ya PoE ikalephera, imatha kufufuzidwa kuchokera kuzinthu zinayi zotsatirazi.
• Onani ngati chipangizo chomaliza cholandira chimathandizira magetsi a PoE. Popeza si zida zonse zapaintaneti zomwe zitha kuthandizira ukadaulo wamagetsi a PoE, yang'anani zida zaukadaulo wamagetsi wa POE musanalumikizane ndi PoE.kusintha. Ngakhale PoE idzazindikirika ikagwira ntchito, imatha kuzindikira ndikupatsa mphamvu chida cholandirira chothandizira ukadaulo wamagetsi wa POE. Ngati PoEkusinthasichipereka mphamvu, mwina chifukwa chipangizo cholandirira sichingathandizire ukadaulo wamagetsi wa PoE.
• Onetsetsani kuti mphamvu ya chipangizo cholandirayo imaposa mphamvu yaikulu yakusinthadoko. Mwachitsanzo, POEkusinthazomwe zimangothandizira muyezo wa IEEE 802.3af (mphamvu yayikulu ya doko lililonse pakusinthandi 15.4W) yolumikizidwa ndi chipangizo cholandirira mphamvu cha 16W kapena chokulirapo, ndipo chipangizo cholandiriracho chingawononge zidazo chifukwa cha kulephera kwamagetsi kapena kusakhazikika kwamagetsi, zomwe zimapangitsa kulephera kwamagetsi ndi kulephera kwamagetsi kwa PoE.
• Onani ngati mphamvu yonse ya zida zonse zolandila zolumikizidwa ikuposa bajeti yamagetsi yakusintha. Pamene mphamvu okwana zida olumikizidwa kuposa mphamvu bajeti yakusintha, mphamvu ya PoE idzalephera.mwachitsanzo, A 24-port PoEkusinthandi bajeti mphamvu ya 370W, Ngatikusinthaimatsatira muyezo wa IEEE 802.3af, Itha kulumikizidwa ndi zida zolandila 24 zomwe zimatsata muyezo womwewo (chifukwa mphamvu ya zida zamtunduwu ndi 15.4W, Lumikizani zida 24 ndi mphamvu yonse ya 369.6W, Osapitilirakusinthabajeti yamagetsi); Ngati ndikusinthaamatsatira IEEE802.3at muyezo, 12 kokha kulandira zipangizo kutsatira mulingo womwewo (popeza mphamvu ya mtundu uwu ndi 30W, Kulumikizana ndi mayunitsi 24 kudzapitirira bajeti ya mphamvu yakusintha, Choncho, mayunitsi 12 okha angagwirizane).
• Onani ngati njira yamagetsi ya chipangizo cholandirira (PSE) ikugwirizana ndi chipangizo cholandirira (PD). Mwachitsanzo, PoEkusinthaimagwiritsa ntchito mawonekedwe A, pomwe chipangizo cholandirira cholumikizidwa chimangolandira kutumizira mphamvu kuchokera kumayendedwe B, omwe sangakhale mphamvu.
