Battery Backup Unit
The RAID Controller includes a Battery Backup Unit (BBU) that maintains
memory content in case of an AC power failure. The main purpose of the BBU is
to maintain the memory during brief interruptions in power, however, it is
capable of sustaining memory content for several hours depending on the type
and size of the memory.
The BBU has circuitry to charge and monitor the battery pack. It includes a
“gas-gage” to monitor the charge state of the battery pack. The battery pack
should be reconditioned prior to the first use. Follow the procedures under
installation to recondition a new battery.
