ABSTRACT:
Described are a system and method of testing connectivity between a main power supply and a standby power supply. The system includes a processor, a main power supply, and a standby power supply. The processor issues a command to the standby power supply to provide dc power to main power supply. The standby power supply switches from providing ac power to providing dc power to the main power supply in response to the command. The main power supply, in response to receiving dc power from the standby power supply, provides a communication that operates to indicate to the processor that the main power supply is receiving dc power from the standby power supply in response to the command.
