Abstract
An information handling system includes first and second power supplies, and a management controller. The power supplies are configured to operate in a first power mode to supply power to the information handling system and in a second power mode to shut down from supplying power to the information handling system. The management controller is configured in a normal operation mode to set the first power supply to the first power mode and set the second power supply in the second power mode. The management controller is configured in a test operation mode to set the second power supply to the first power mode, to set the first power supply to the second power mode, to determine whether the second power supply is operating within a first limit, and when the second power supply is not operating within the first limit, to provide a first indication that the second power supply is failing.
