We in Engineering think this is fine and works. It's probably obvious but:
1. observe software environmental monitoring to verify both PSUs are up and running. 2. power off one PSU (using AC switch on PSU) 3. unplug from 110V and plug into 208V 4. power it back on 5. observe software environmental monitoring to verify new PSU is up and running. 6. repeat process for the other PSU 7. observe software environmental monitoring to verify both PSUs are up and running.

It works. I've done it. Gotta check on support.

Let us know if it works :-)

..shouldn't be a problem. The low-side of the Power Supply is the same for both high-side voltages. So, assuming you're plugging into a 208V power source on the "new" Power Supplies, it should work fine.

I certainly would not be brave enough to try that. Not sure what having 208 on one side and 110 on the other would do, but seems like a potential for disaster.

Our filers and shelves are currently on 110v power. We'd like to switch to 208v, possibly without downtime. I'm thinking of moving each power supply one by one from 110v to 208v. Are there any issues doing it this way?
Thanks
