Managing BBU Information

If your SAS controller has a BBU, you can view information about it and change some settings.
A learning cycle is a battery calibration operation that the controller performs periodically to determine the condition
of the battery.
Perform the following steps to view and change the battery settings:
1. Navigate to the second Controller Settings screen and select Manage Battery.
The Battery Properties dialog appears. Most of the battery properties are read only.
