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.

I

For further information, please refer to the "ServerView Suite RAID

Management" user guide, available online at

http://manuals.ts.fujitsu.com

or from the ServerView Suite DVD 2 supplied with your PRIMERGY server.

Ê

If the BBU is shown as bad or defective, do not power off the server for at least 8 hours to allow the charge and calibration cycles to finish.

Ê

If the BBU status does not change after 8 hours, please try to initiate the recalibration process manually using the ServerView RAID Manager.

I

If this procedure still does not fix the BBU status, please contact your local Fujitsu customer service partner.
