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 

— 

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.
