Almost certainly Token Ring over CAT5 cable. I checked the part number
since I'm at work at the moment, but it turned up nothing - but that may
not be the actual part number (AIUI there is an assembly p/n and an FRU
p/n, and our parts checker only works for the assembly one. And possibly
for a limited range of parts at that.)
