The Yealink YLPOE30 is a power over Ethernet adapter that is designed to power the Yealink CP960 IP conference phone and other 802.3 AF/AT PoE devices. PoE injectors greatly simplify installations where no other PoE sources are available, or providing a PoE switch is not a cost-effective solution. The YLPOE30 is compatible with most 48V PoE devices, even if they are not Yealink products.
