Description

 

 

 

1

Green

System Power LED. This LED is on 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 is on 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.
