RMX 4000 - CNTL 4000 Blinking



The CNTL 4000 on my RMX 4000 is continous blinking in the following sequence:


HS - Blue

ACCT - Orange

RDY - Green

ERR - Orange


I rebooted two times and nothing happens, blinking stays. I can't remote into my RMX 4000, it doesn't work.


The MPMx-D x 2 is also blinking a blue light. Please help!

Hello @Matt W. ,


Welcome back to the Poly Community.

I am not sure we have publicly facing information regarding the recovery procedure via a USB stick so you should contact Poly support.


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
