CEM 3 update version

Please contact your local ETC Authorised Service Partner to have your racks updated. Power Control processors rarely need to be updated. What is the reason for wanting to update?

Hi Corey,

Our CEM3 controllers have different versions: 1.5.1, 1.6.1, and 1.7.2. We had 2 CEM3 controllers fail due to a boot loop last year, and they only lasted a year after removing the test switch. Is updating using USB feasible? Thank you.

Removing the test switch would require a hardware modification of the CEM3 - why was the test switch removed? 

I would advise that you contact ETC Support who can recommend the next best possible steps - which could also involve how to update the CEM3s if necessary:
