Cascading allows the system to access data at a faster rate by allowing several
backplanes to share resources to reduce latency time.
The first backplane in a cascaded system requires a motherboard and HBA. Other
servers require a power control card, not a motherboard and HBA. For more infor-
mation, see the SC936 chassis manual.
