processor card in
position M02
Embedded in the Loop number 256 is an internal
system unit loop embedded in the system
backplane in unit backplane. The loop goes
position MB1 from the NIC, to the embedded
HSL I/O bridge, and back to the
NIC with no external HSL ports.
Loop number 257 has external
HSL ports labeled "A0" and "A1"
