Monitoring the Battery Backup Unit
The optional Battery Backup Unit (BBU) maintains memory content in the presence of an ac power failure. The
principal purpose of the BBU is to provide stable memory power during ac power glitches and short power outages,
however, the BBU is capable of sustaining memory content for an extended period. The length of memory power
backup is dependent upon the cache memory size and the particular battery pack used by the BBU.
To monitor the charge status on a Battery Backup Unit (BBU), select a BBU from the navigation area. To view BBU
information, click BBU->Properties from the menu bar.
