Hi [NAME] Swirly,   The chassis only have 1 CMC module only? Was it working before? Are you able to ping the CMC module IP? Can you try to SSH/Telnet or Serial into the CMC to check if there is any output?   You may need another CMC to check if it's the chassis slot issue. If you do not have any spare, ultimately you may need to replace the CMC, as most of the users in the community changed the CMC in order for it to work. 
Hello, I was wondering if someone could help me with figuring how to get the CMC module to work. I have one CMC module that when the enclosure is turned on throws an error saying “ The CMC is not responding.” I have tried moving it back and forth from both CMC slots but I still have that error. I am using three PSUs that support 110v and all have there bottom LED green. No other components are plugged in.
