Agreed. The only tbolt cables attached, serial and PPS, ran around
the edge of the room into a closet to the dead server. That same path
also had a handful of cat-5 network cables, connected to now-dead

I figure it's worth a try--the 10 MHz output is active, the GPS

Yep, AC04 next to the PPS jack.
You may need to get in there and probe a bit. In my case, my bad
RS232 driver was drawing about 350mA and getting VERY hot, VERY fast.
