Battery pack LEDs

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.

— 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 (http://www.hp.com

— Double blink,

then pause

The cache microcontroller is waiting for the host controller to

communicate.
