FCAL Base and Expansion Backplanes with Single Loop (A)

Note: When installing the Expansion Backplane, you must cable 'Loop B' from Base to Expansion (cable part #530-2622). This is a requirement even if you are NOT driving 'Loop B' from the X6727A (375-3030) card. This is needed to maintain arbitration and loop integrity between backplanes.
