Description
System Power LED. This LED glows steadily when the system is powered on 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 glows steadily when 3.3 V auxiliary voltage is detected.
The auxiliary voltage is used to preserve BBWC data and is available when system
power cords are connected to a power supply.

LED 4 State Interpretation
One flash every The system is powered off and the cache contains data that has not yet been
two seconds written to the drives. Restore system power as soon as possible to prevent data
loss.
Data preservation time is extended when 3.3 V auxiliary power is available, as
indicated by LED 2. In the absence of auxiliary power, battery power preserves
the data. A fully-charged battery can normally preserve data for two days.
The battery lifetime also depends on the cache module size. For more information,
