The system is powered down, and the cache contains data that has
not yet been written to the drives. Restore system power as soon as
possible to prevent data loss.
Data preservation time is extended any time that 3.3 V auxiliary
power is available, as indicated by LED 2. In the absence of

Data preservation time is extended any time that 3.3 V auxiliary
power is available, as indicated by LED 2. In the absence of
auxiliary power, battery power alone preserves the data. A fully-
charged battery can normally preserve data for at least two days.
The battery lifetime also depends on the cache module size. For
further information, refer to the controller QuickSpecs on the HP
