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.

5.5 Replacing a Faulty PSU

WARNING!
Before you install a replacement PSU, be sure that the
warning text on its extraction handle is the same as that on the
handle of the other PSU. Double-check to avoid mixing a
similar yet incompatible PSU of another EonStor series.
When a PSU fails, it should be replaced immediately.
However, do not remove the PSU unless a replacement is
readily available. Removing a PSU without a replacement will
cause severe disruptions to the internal airflow and the
subsystem will overheat. This may lead to
damages to some of the subsystem components.
To replace a PSU, please follow these steps:
