Network Group 0: Shelf 0 to Shelf 1
Each Single Group System contains one Network group, Group 0. Each
Network group is comprised of two Network shelves: Shelf 0 and Shelf 1.
The Core/Net modules contain Network Group 0. Shelf 0 is in Core/Net 0,
Shelf 1 is in Core/Net 1. Shelf 0 must be connected to Shelf 1 for Network
Group 0 to operate correctly.
