2.4 Power over Ethernet on the Duckfone
The Duckfone must be powered over Ethernet (not supplied by default). We recommend an active
(auto-sensing) POE injector that supports a minimum of 30W. Check that your PoE adapter complies
with IEEE802.3at standards or higher.
Beware of the quality and compliance to standards of many POE injectors on the market. We
recommend you source your POE injector from a reputable manufacturer that has a proven record of
meeting compliance requirements and manufacture their equipment to these standards.
