I have an M1000e that I have started having power issues with since recently replacing the UPS units it is connected to. The enclosure is fully populated with a mix of M610 and M710 blades, and 6 x A2360P-00 power supplies. The problem is when the UPS unit fails over to battery power, all of the power supplies in my blade lose power for a few seconds. I have been troubleshooting this for about a week, and I finally tracked it back to an issue with the power supplies in the blade. After swapping 4 of them out with E2700-P models from a new chassis we just purchased, they stopped dropping during failover. I think the problem may be related to the UPS voltage going from 200V on wired power to 208V on battery. The older PSUs seem to have an issue adjusting without temporarily losing power. Anyone ever heard of this issue before, or have any suggestions? Maybe the older PSUs just don't handle the voltage fluctuation as well for some reason?
