Dual power supplies, dual voltage

I have a DL360p with dual power supplies.  What would happen if I plugged one of the power supplies into a 220V outlet and the other into 110V?   I'm thinking it'd be fine, assuming the power switching is handled within the power supply itself and not by some software module.    But I'd like to be sure.

Re: Dual power supplies, dual voltage

You are correct that this switching is the auto-sensing feature of the power supply. we have had redundant supplies plugged into different voltages without problems.


Supply1 connected to 115vac HP PDU, supply2 connected to 220vac HP PDU.


We were updating our power distribution from 115 to 220...
