Installing and removing the RAID BBU

If power to the SAS controller on the SAS module drops below specifications, the optional RAID BBU maintains the contents of the DIMM by keeping the cache in self-refresh mode until power is restored. After power is restored, the data is safely written to the drives, maintaining the integrity of the disk array.

To install the RAID BBU:

1Perform the pre-installation instructions described on page 39.

2Remove the processor air baffle. Perform instructions described in “To remove the processor air baffle” section on page 45.

3Remove the SAS module. Perform instructions described in “To remove the SAS module” section on page 89.

4Align then insert the RAID BBU into the battery connector on the SAS module.

5Secure the RAID BBU with the three screws provided.
