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 5.
