Orbi RBS50 reset does not respond

Thanks FURRYe38. I executed factory resets before, and have read both the manuals and every possible post on that topic, so I know what sequence to expect. I would be ready to assume that the ring led light is failed, but since I am not even detecting any signal from the unit when it's hard wired directly into my ethernet switch, I am rather guessing that power is not getting past the led light. 

The satellite is less than a year old, and still under hardware warranty, so I can request an RMA. I was just hoping someone here would have a magic trick or workaround.

Thanks again !
