A technique involves providing a set of soft start power signals to operating circuitry mounted on a circuit board. In particular, the technique involves enabling (i) a first converter to provide a first soft start power signal to the operating circuitry and (ii) a second converter to provide a second soft start power signal to the operation circuitry. Additionally, the technique involves providing a first control signal that indicates whether the first converter properly provides the first soft start power signal, and providing a second control signal that indicates whether the second converter properly provides the second soft start power signal. Furthermore, the technique involves disabling the first converter if the second control signal indicates that the second converter improperly provides the second soft start power signal, and disabling the second converter if the first control signal indicates that the first converter improperly provides the first soft start power signal.
