Abstract: A device may select a power supply module (PSM), from a plurality of PSMs that operate in a current sharing mode, for performing a health check. The device may perform the health check on the selected PSM by iteratively modifying an output voltage of the selected PSM and monitoring for a corresponding modification in an output current of the selected PSM. The device may determine whether the selected PSM is capable of delivering a particular load without a failure based on performing the health check. The device may perform an action based on whether the selected PSM is capable of delivering the particular load without the failure.
