Operational Behavior of dc Power over Voltage Range
The following graphs describe operational behavior as a result of the
input dc voltage on a storage system (CX700 or DAE). Voltages are
approximate, /- 1V.

Whenever either power supply indicates operation in the
input low
range, system software disables write caching, clears the write cache, and
operates in data write-through mode. The transition to write-through
mode takes less than 90 seconds. The DPE2/DAE will continue to operate
