I have a 1400RM UPS. It was powering a server set-up with about three or four severs and ten or so boxes.
I unplugged it and took it elsewhere. When I plugged it in again, not a bean. No lights, no power nothing in the batteries, no glimmer, nothing on reset, nothing on reset batteries (with the power unplugged). Nothing on pressing the sensitivity reset button either.
Admittedly I did leave it for a few months while I tried to figure out what was going on with it plugged in but not registering anything.
Anyone know what gives? APC just says buy another unit.
