We found that the power supply was at fault. I am told the MESH group is aware of the need to fix this lack of power indicator.
The power problem we had was the wiring got mixed up and the hot (blk) was not getting a 120V.
We found the problem by Having another RAP POE supply. So we powered a MAP using this cable and found it discovered the RAP and controller ... just like in the books!!! Of course, if the unit is new, it may take time for the OS code to load over the wireless link and reboot (5-15 minutes).
