UPS in the vacuum rack failed this afternoon, cutting off power to the vacuum control system.  After plugging all the stuff that had been plugged into the UPS into the wall, everything came back up.  It appears that V1 closed appropriately, TP1 spun down gracefully on its own battery, and the pressure did not rise much above 3e-6 torr. 


The UPS fizzed and smelled burnt.  Rana will order a new, bigger, better, faster one.
