Having a primary device configured at Logical Rack 1, Logical
Group 2 (bit 5) would be illegal since this image space is already
being used by a complementary device. Having a complementary
device configured at Logical Rack 10, Logical Group 2 (bit 9) would
also be illegal since this image space is already being used by a
primary device.
