Notes:
a. The battery card assembly protects the integrity of the cached data on the RAID controller by
providing backup power up to 72 hours in the case of a complete ac power failure or a brief power
outage. It has built-in functionality to charge the battery pack automatically and to communicate
battery status information such as voltage, temperature, and current to your server. It also provides
an inexpensive alternative to using an uninterruptible power supply, and a second level of fault
