b. Highly available, write-caching configurations require that
you connect the first disk enclosure in a storage system (EA 0,
bus 0) to a Standby Power Supply (SPS) for enclosure power.
An integrated disk-and-processor enclosure, such as a CX300 or
CX500-series DPE2, is always the first disk enclosure on the first bus

SPS.
