What Patrick said.

But, on a minor note that probably won't affect your Symmetra but I'm posting in case anyone else here can shed light on.... we had a power event this AM. The transfer switch did it's magic and all was good... Except for two new APC1400's- they failed once the batteries drained. I triple-checked that they were on the right panel, played with sensitivity, even tried daisy-chaining one off a good working 2200. Nothing I did would convince the two 1400s they had power. Once the house power was restored they came back to life and look normal. I later learned that two of our colo customers with APC1400s had the same problem :( Other models (even a couple non-essential lower-end, dumb APC 450s and 650s) didn't blink at the generator power.
