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

Replacing a Failed PSU Module
5.4.1 Notes on PSU Module Maintenance
Redundant (N+1) PSU modules
: The subsystem comes with three fully
redundant, hot-swappable PSU modules. These modules are accessed through
the rear of the subsystem.
Immediate replacement
: When a PSU fails, it should ideally be replaced
immediately. Do not remove a PSU module 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, possibly causing
irreparable damage to some of the subsystem components.
WARNING!
Although the PSU modules are fully redundant, it is not advisable to run the
Falcon 24 Bay subsystem with any failed PSU module for a long period of time.
If a second PSU module fails, the subsystem will enter an idle state.
