Replacing
a Faulty PSU
Figure 5-10: BBU LEDs
NOTE:
1.
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.
2.
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.
3.
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 Rorke’s standard RMA procedure.

Two (2) redundant PSUs:

converter unit and the cooling module. The PSU is located in the lower

When removing the PSU from the subsystem, the cooling module is
also being removed.
Immediate replacement:
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
