Note on BBU charging and calibration
The BBU may be deeply discharged due to extended storage time and wrongly
show as bad or defective in the ServerView RAID Manager.
In this case, the BBU will automatically enter a trickle charge cycle for recovery.
This initial charge may take up to 8 hours before the BBU will initiate a
recalibration cycle.
Ê Enter the ServerView RAID Manager and check the current BBU status.
