Hi guys,
After instructing the DC technicians to swap the stacking cables around,
BOTH ports magically came up and everything is working as expected, 32Gbps
full ring.
I can only assume that even after asking (and them checking) three times,
the stacking cables wasn't seated properly on one or more of the ports.
Many thanks,
Chris.

May be a faulty cable/ module.
You may want to try first with only one cable, and then with the other. Then
try different ports with one cable only.
