Description
System Power LED. This LED illuminates 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 illuminates steadily when 3.3
V 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.

LED4 pattern Interpretation
One flash every The system is powered down, and the cache contains data that has not
two seconds yet been written to the drives. Restore system power as soon as
possible to prevent data loss.
If 3.3 V auxiliary power is available, as indicated by LED 2, then data
preservation time is extended. If no auxiliary power is available, only
battery power 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 more
information, see the controller QuickSpecs on the HP website
(http://www.hp.com).
Double flash, then The cache microcontroller is waiting for the host controller to
pause communicate.
