FCAL Base and Expansion Backplanes with Dual Loops (A and B)

Note: When LoopB is configured, the external Port 1 of X6727A (375-3030) cannot be used for additional external storage.
This would extend the internal loop B outside of the box, which is not supported. Making use of the second external port off X6727A is supported.
