Things to note:
The power source may have been disconnected to the appliance, or the appliance lost power due to scheduled maintenance. There could also be a genuine case of PSU cable failure. If the power has been restored after the interruption, users can validate the status of the PSU using the commands provided. This alert can be considered a false positive if this was a temporary interruption. If not, Dell support can be engaged for assistance and a support request can be opened for work order.
