A dropout of 5 seconds sounds like an ethernet cable or loss of link. See if wiggling and tugging either end of the cable causes the link light go out. Try a different cable too.

We have certainly seen roboRIO ports broken off the board, but not often. I haven't seen whether the OpenMesh is soldered through the board or to the board. See if either one of them wiggles within the device and causes the issue.

Please let us know what you find.
