 See.. now.. you're clearly talking about power protection.. but, you see
 we _weren't_ talking about power outages, we were talking about
 compromising emanations being sent through power lines.. and as far
 as the UPS goes, whether or not a UPS would help such muffle such
 emanations. >>

prevent large surges (such as the type that occurs when lightning hits your
incoming power.
