I believe that I am running the latest firmware (1.1.5.6). One thing that I noticed is that the issues wont appear as much on good power scenarios (Like on large and well prepared clubs or when running on a generator). I was able to cause a failed startup (3 out of 5 tries) by connecting one of the amps to an ungrounded power cord (5 out 5 good startups at the same amp on grounded cord). Could a grounding issue be the problem? I also noticed that when the rack is not connected to a grounded AC, I can get a really nice shock by touching the amps. IS that ok?
