After powering ON RMX 2000 by switch on the rear side MPMX and RTM modules LEDs blinks but LEDs on the CNTL module are OFF. Is where an option at WEB interface to powerON CNTL or it probably dead.
I have repaired RMX power supplies after a power surge but i dont have actual WEB config to connect to it.
I searched for an answer to your question, and I think you will have to replace the CNTL module. It is quite easy, but if you won't be able to replace it on your own, just let me know. I'll post the steps to do the needful.
