  1. Any BBU failure must first be evaluated to ensure the current controller code is running before replacement.​​​​​ Especially for the following major releases:
  • 08.20.XX.XX - Must be or greater
  • 08.25.XX.XX - Must be or greater.
  • 08.30.XX.XX - Must be or greater.
  • 08.40.XX.XX - Must be or greater.
  • All other releases by the platform can be verified in the SANtricity Support Matrix

2. If the controller firmware is not current as listed above, the firmware must be updated first.

3. After the firmware is updated, a new manual learn cycle must be run - How to manually start a battery learn cycle using SANtricity

4. On rare occasions, this may need to be run twice to fully recover a battery affected by previous downrev code issues.
