Power supply failure generally results in the loss of one or more output voltages.
However, protection circuitry in the power supply regulator circuitry 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 PS19 DC lights when any of the
output voltages are below specification and/or when either the F1 or F2 fuse blows.
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.
