Need to upgrade PDU's and keep server running

I plan to change PDU's providing power to a DL server. Currently have it running on 120v 20 amp dual power supplies. The new PDU's will be 208v, 30 amp. I realize the Power supplies (PS) are auto sensing. Is it OK for server to be running one PS on 120v and the other 208v for a few minutes while swapping one side at a time, and upgrading both the 208v, L6-30? I want to keep server running during the upgrade.

Its not a good idea to different voltage running on server.

What the exact server it is, please mention the server model number.

My suggestion to go with same voltage, 120v 20 amp dual power supplies

LOL - Read the first message again. It WILL be on the same PDU type eventually. But as I do the switch, one PS will be on old 20 amp/120v while the other PS is on the new 30 amp/208v. I am not changing power supplies (PS). I am upgrading PDU's.

Re: Need to upgrade PDU's and keep server running

The question is existing running voltage any issue with server?

L6-30 - single phase and only has 3 prongs. 2 hot, 1 ground.

How many phase currently you using?

Considering the PDU changes whichever input it is designed for, into what the server needs, you should be fine mis-matching.
