one layout:
Variation on Case 1: A single DTA 200 backplane over one DTA 201 backplane,
in this case, the traffic cop skips rack 2 and defines modules in racks 1 and 3.

Variation on Case 2: A DTA 200 backplane and one DTA 201 backplane over one
DTA 201 backplane, in this case, the traffic cop skips rack 3 and defines modules
in racks 1, 2, and 4.
