Description
System Power LED. This LED glows steadily when the
system is powered up and 12 V system power is
available. This power supply is used to maintain the
battery charge and provide supplementary power to the
cache microcontroller.
Auxiliary Power LED. This LED glows steadily when 3.3V
auxiliary voltage is detected. The auxiliary voltage is
used to preserve BBWC data and is available any time
that the system power cords are connected to a power
supply.

One blink every The system is powered down, and the cache contains data that has
two seconds 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 (http://www.hp.com).
