Thanks Patrick. I agree with your assessments. The ITMX issue appears to be a shutdown of the satellite box, I suspect, related to the door operations as it went zero late morning yesterday. I don't suspect a failure at this point but maybe the power supply has unplugged--it should be screwed in but if not then it could have been disrupted. I'll open a ticket and investigate. FRS 10551.
