Ok, thank you.   Do you happen to have a known good CMC, such as from another unit, that we can test in this system? The reason I ask is I want to try to eliminate the issue being caused by a double failure of the CMC's, albeit very rare I just wanted to confirm. If you try and the result is the same then I would bet that the issue is that the power outage you described failed the Control Panel itself. If you try and it isn't the same, then the issue is that the power outage failed both of your CMC's.   Let me know what you see.    
Hello, We had a bad power failure and our M1000e does not boot anymore. The lcd panel display CMC not responding a few minutes after powerup. The top led on the CMC is amber steady and the bottom light starts blue and goes amber steady. I have the same thing for both cmc. I tried to pull one of them to see if it would make a diffrence but I get the same result. Does that mean that both cmc need to be replaced ? Any help would be appeciated as this is urgent. Thank you Gilbert
