Some UPSs are back up power but they have to switch over from the pass thru AC outlet on the UPS to the battery. You have another problem, it appears that the ram battery on the XTs CPU card could be dead and that is the real reason the system lost programming including card slot configuration and ringing assignments. Even a good UPS won't protect you from issues if the power outage is longer than the back up time of the UPS if your RAM batter is bad.
