The cRIO does not have a shock sensor. The data sheet showing the shock and vibe testing is here ..

If you are in a relatively static-free environment, you can clean debris from the cRIO in about five minutes. I almost always find lots of glitter and wire bits. I have seen cases where the reboots ceased for the remainder of the matches. I have also seen cases where nothing improved. Procedure link is below.
