APsystems ECU-R network setup

I have an APsystems YC600 microinverter system with zigbee network connections to an APsystems ECU-R. When the ECU-R is connected to any of my LAN router ports it never requests a DHCP IP address. Anyone with the same type of network installation have this problem? I have it attached wirelessly to the router now, but its MAC address does not show up in the attached DHCP client tables.
