BBWC module LEDs
Item ID Color Description
1
Green 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.
2
Green Auxiliary Power LED. This LED illuminates 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.
3
Amber Battery Health LED. To interpret the illumination patterns of
this LED, see the following table.
4
Green BBWC Status LED. To interpret the illumination patterns of
this LED, see the following table.

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