Interpretation
—
One blink every
two seconds
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
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
website (

Double blink,
then pause
The cache microcontroller is waiting for the host controller to
communicate.

capacity expansion, stripe size migration, and RAID migration) are
temporarily unavailable until charging is complete. The recharge
process takes between 15 minutes and two hours, depending on the
initial capacity of the battery.

Steady glow
The battery pack is fully charged, and posted write data is stored in
the cache.

The battery pack is fully charged, and there is no posted write data
in the cache.
