Why do I see BBU warning events periodically?


Last modified date: 2017-11-28

In ES1640dc / ES1640dc v2 system, there are dual controllers in the enclosure and there is one BBU(Battery Backup Unit) in each controller. There is a BBU learning design to maintain the battery performance, which does the BBU discharges and charges periodically. (default cycle: 4 weeks)

During the BBU learning, a warning message is sent to system event log and it is normal behavior.  

To change BBU settings, you can configure it in System Settings >> Hardware >> BBU
