Thanks Jonathon, I don't think the jumper is the issue, as it was working fine for years and has only recently started misbehaving following a few months of being switched off. It's been mounted in a rack the whole time.
I'll suggest to them to remove it from the rack, and inspect the front panel PCB and any connections to the ROACH2 board. If we find out anything, I'll report back here.
