Replacing A Faulty Psu; Notes On Psu Module Maintenance - Infortrend EonStor S12E-R1132-4 Installation And Hardware Reference Manual

NOTE:
․
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.
․
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.
․
The chance of charger failure is comparatively low. If the
cause of a failure cannot be determined even after a BBU is
replaced, contact your system vendor for a replacement
controller and return the controller module through
Infortrend's standard RMA procedure.
