The output control unit 72 turns on the switches 42A1 to 42A3 according to the received command. Thereby, power supply to the load devices 13A1 to 13A3 is started.

  At this time, when the order and timing for turning on the switches 42A1 to 42A3 are set, the output control unit 72 turns on the switches 42A1 to 42A3 in the set order and timing. Thereby, the power supply to the load devices 13A1 to 13A3 can be started, and the order and timing of starting the load devices 13A1 to 13A3 can be controlled.

  Instead of controlling the order and timing of turning on the switches 42A1 to 42A3 by the output control unit 72, the PDU management unit 83 of the information processing apparatus 14 is set with data for commanding the switches 42A1 to 42A3 to be turned on, respectively.

As a result, the order and timing of stopping power supply to the load devices 13A1 to 13A3 can be controlled in accordance with the time required for the shutdown of the load devices 13A1 to 13A3.

  In addition, instead of controlling the order and timing of turning off the switches 42A1 to 42A3 by the output control unit 172, the PDU management unit 183 of the information processing apparatus 112 sets the data for instructing the switches 42A1 to 42A3 to be turned off, respectively.
