Replacing the Cache Battery
A cache battery or Battery Backup Unit (BBU) is optional on VessRAID. If your
system has a cache battery, it is located inside the RAID controller. The battery
assembly is replaced as a unit.
To replace the cache battery:
1. Verify that the Battery LED is amber or red. See Figure 7.
Figure 7. VessRAID enclosure LEDs
2. Shut down the VessRAID.
See “Shutting Down the Subsystem” on page 131 or page 284.
3. Shut down the VessRAID and remove the RAID controller.
See “Replacing a RAID Controller” on page 320.
4. Lay the RAID Controller on a non-static surface and remove the cover
attaching screws, one on each side, then remove the cover.
See page 322, Figure 4.
