We continue having problems with Tripleteststand loosing communications with the IO Chassis. Tripleteststand did not recover after power down power up reset. Richard M. replaced cards in the IO Chassis and Jim B. restarted IOP, the x1sushxts27 model, and Burt restored the system from 20120622-x1sushxts27_PR2.snap. The Tripleteststand is up and  appears to be running normally.
