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:
1
Perform the pre-installation instructions described on page 39.
2
Remove the processor air baffle. Perform instructions described in
“To remove the processor air baffle” section on page 45.
3
Remove the SAS module. Perform instructions described in “To
remove the SAS module” section on page 89.
4
Align then insert the RAID BBU into the battery connector on the
SAS module.
5
Secure the RAID BBU with the three screws provided.
