Re: Fried Ethernet Ports

2077 had a physical port failure in competition this weekend, followed by complete control system failure which we presume, but haven't proved, was related.

In setting up for our next-to-last match one of the ports broke (we use both, one for field and one for a dashboard/video feed to a laptop). They finished the match OK, minus the laptop connection. We didn't have time to swap in a backup for the next match, so we ran it the same way. This time nothing, as in "robot didn't move at all".

The odd thing is that when we brought it back to the pits and tethered, everything seemed fine.

It was a real downer to end the competition on this note, but more troublesome is having an undiagnosed major major system failure with another competition coming up soon. The plan now is just to get another DS and hope that fixes it (the broken unit is in the crate and on its way), but it would be great if someone could help us make sense of the situation. Any advice?
