Filiberto, Patrick I didn't realized it had been removed, and except for communication errors with the missing chassis, the PLCs ran on without apparent incident. Filiberto made the same modifications as to the one at end X and reinstalled it. I updated the system manager accordingly, checked it into svn and activated it. This time I didn't restart the PLCs, but I still had to restart the EPICS IOC. I burtrestored to 6:10 this morning.
