That sounds an awful lot like how I ended up plugging one PSU on our E4A into the UPS, and the other directly into the wall. An idea that was questioned and even ridiculed when I first mentioned it on the List, but we'd had cases in which a UPS self-test failure caused a long enough interruption to bring down the system, and our E4A is so lightly loaded that the only consequence of running it on only one PSU is having to go into SST and clear the warning light.
