-5: Installing a BBU Module
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.
5.4. 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
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.
