Replacing A Faulty Psu; Psu Overview - Infortrend EonStor S12S-G1033 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 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 near its life expectancy.
˙
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.
