on the Base and Fabric interfaces.

Base Interface
The blade slots are numbered physically from 01 to 16 going left to right along the
front of the shelf. Each slot also has a "logical" slot number that defines it for
backplane connectivity; logical slot numbers are not shown on the shelf. Please note
that the slots will be referred to by their physical slot location.
The base hub slots (physical slots 1 and 16) have four pairs of 1000Base-T signals to node slots
which form the dual star topology fabric. Each of the node slots support two base channel
interface signals that connect to each hub slot. In turn, the channel 1 base interface of each hub
slot is connected to the SAM. Each of the hub slots support a total of 16 base channels.
The hub slots require connectors P23 and P24. The base node slots require only connector
P23.
