Item ID Color Description
1 Green 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.
2 Green 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.
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.

Interpretation
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 (http://www.hp.com).
The cache microcontroller is waiting for the host controller to
communicate.
The battery pack is below the minimum charge level and is being
charged. Features that require a battery (such as write cache,
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.
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.
An alternating green and amber blink pattern indicates that the
cache microcontroller is executing from within its boot loader and
receiving new flash code from the host controller.
There is a short circuit across the battery terminals or within the
battery pack. BBWC features are disabled until the battery pack is
replaced. The life expectancy of a battery pack is typically more
than three years.
There is an open circuit across the battery terminals or within the
battery pack. BBWC features are disabled until the battery pack is
replaced. The life expectancy of a battery pack is typically more
than three years.
