Monitoring Battery Backup
Multiple utilities are available to display and configure BBU information including recharge count.
When you replace a BBU, you should reset this counter to zero. Intel recommends that you replace
the BBU once per year or after 500 recharge cycles, whichever comes first.
Note: This chapter describes only the BBU-related features of the Intel utility programs. For
complete information on these utilities, see the Intel
®
RAID Software User’s Guide.
