Beschreibung
Zusammenfassung:	A power supply control circuit includes a plurality of ports, and a plurality of power supply units that each turn on and off the power supply from the power source to the load connected to the port. The power supply control circuit also includes an identification information acquisition unit, a sequence information storage unit, and a switch control unit. The identification information acquisition unit acquires identification information from the loads connected to the respective ports. The sequence information storage unit stores therein power-up sequence information and power-down sequence information specified for each of the loads. The switch control unit causes the power supply unit to turn on and off the power supply to the load corresponding to the identification information, according to the power-up sequence information and the power-down sequence information specified for the load.
