Chapter 5: Subsystem Maintenance and Upgrading
Figure 5-15: BBU LED on S12F-G1433
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.

damages to some of the subsystem components.
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
To replace a PSU, please follow these steps:
