Hey guys, quick question - we have an Equallogic PS6510x with triple redundant power supplies rated at 440W each, the building has two circuits, each on an independent UPS. From what I understand, the EQL draws around 800W, and thus relies on two power supplies being online at any given time. Is there some way to wire this so that a UPS/Circuit failure doesn't take down two power supplies at the same time, causing a crash of the system?

I'll elaborate later if more details are necessary, I couldn't think of a solution off hand.

Thanks!
