UniFi - How do secondary Ethernet ports work on UAPs?

Answer


Secondary UAP Ethernet ports don't provide PoE passthrough (to run current to a second powered device), but they do support data passthrough. It serves as a bridged interface between main / secondary Ethernet port.

This means users can connect the PoE cable to the main Ethernet port to supply power, then connect another, non-PoE device (e.g., IP camera, extra UAP) to the secondary Ethernet port to bridge connections.
