Claim:
1. A method comprising: receiving, by a voltage comparator, an input voltage of an Oring-FET and an output voltage of the Oring-FET with the Oring-FET being in a redundant power supply configuration; comparing the input voltage and the output voltage, wherein comparing the input voltage and the output voltage determines whether the Oring-FET is faulty during power up; in the event the input voltage is less than the output voltage during power up, the Oring-FET provides output to a communicatively coupled system bus; and in the event the input voltage is approximately equal to the output voltage during power up, the voltage comparator assists in preventing inrush current from flowing from the communicatively coupled system bus when another redundant power supply configuration is providing power to the communicatively coupled system bus.
