NOTE:
1. A new or replaced BBU takes at most twelve (12) hours to
charge to its full capacity. Reset the subsystem whenever a
BBU is replaced or added in order for the new BBU to take
effect.
2. The life expectancy of a BBU is more than one year.
However, it is considered a safe procedure to replace the
BBU every year. Follow the procedures above to replace a
used BBU with a replacement in order to maintain the fault
tolerance feature.
3. The new BBU with Infortrend’s ASIC400 subsystem series
comes with an EEPROM for recording FRU data. By
checking against the system real time clock, firmware will
generate a “
Charge is low, replacement is recommended
”
event when a BBU is used for over a year.
