One more update.  Moments after sending this email (approximately 3 or  
4 minutes after pulling the UPS plug to test the OB/OL status) the UPS  
shutdown hard, crashing all attached computers!

Power had been restored... but whatever sequece was initiated when the  
power went off, wasn't undone when it came back.  :(
