Power supply failure generally results in the loss of one or more output voltages.
However, protection circuitry in the power supply regulator may shut down a regulator
due to a current overload caused by an external fault.
The red
Alarm
indicator on the front panel of the power supply indicates any failure
within the unit.
The red
Alarm
indicator illuminates if any voltage supplied by the
power supply is outside of specification. This could be caused by an
internal or external fault. If the alarm indicator illuminates in a
replaced power supply, the fault is not within the unit.
All maintenance activities are to be carried out by a qualified service technician.
The red
Alarm
indicator can be activated by malfunctions in the backplane, the power
supply, in any of the cards inserted into the cage, or in any of the above in a connected
cage.
If the power supply is turned ON and the green power indicator is OFF check the
following:
1.
DC power input connector (see
Figure 7-4
)
2.
DC power supply interruption
3.
Blown main or circuit fuse/breaker in the building electrical panel
