Chapter 6
Using the Intelligent
Battery Backup Unit
This chapter explains how to monitor and maintain the iBBU for your
ServeRAID M5025 SAS/SATA controller. Most of the iBBU functions,
such as battery recharging, occur automatically. Click on the following
links to view instructions on how to use the iBBU:

Section 6.1, “Monitoring the IBBU with the MegaRAID Configuration
Utilities”

Section 6.2, “Replacing the Battery Backup Unit”

Section 6.3, “Resolving a Configuration Mismatch”
You can monitor the battery status (temperature, voltage, and so on) in
these MegaRAID
®
utility programs:

WebBIOS Configuration Utility

MegaCLI (Command Line Interface)

MegaRAID Storage Manager (MSM)
The MegaRAID utilities display a counter showing the number of times
the battery pack on the iBBU has been recharged. When you install a
new iBBU, the battery recharge cycle counter for the iBBU is
automatically set to zero.
Note: For optimal performance, replace the iBBU once a year.
This chapter describes only the iBBU-related features of the MegaRAID
configuration utility programs. For complete information on these utilities,
