Power supply unit, processing system, and control method

摘要

A power supply unit includes a communication unit and a control unit. The communication unit is capable of communicating with a different power supply unit. The control unit determines a number of processing units connected thereto, controls powers of the processing units connected thereto so that one of a turn-on operation and a turn-off operation is performed on the powers of the processing units in sequence, and controls the powers of the processing units connected thereto so that one of the turn-on operation and the turn-off operation is performed on the powers in a predetermined priority order in a relationship with processing units connected to the different power supply unit through communication with the different power supply unit.

1. A power supply unit operatively connected to a plurality of processing units, the power supply unit comprising:
a communication unit configured to communicate with a different power supply unit operatively connected to a different plurality of processing units; and a control unit configured to determine whether the power supply unit is a head power supply unit or a relay power supply unit with respect to the different power supply unit, and control powers of the plurality of processing units connected to the power supply unit such that the plurality of processing units connected to the power supply unit are configured to sequentially turn on or turn off in an order based on whether the power supply unit is a head power supply unit or a relay power supply unit and based on a predetermined priority, wherein,
the control unit is configured to judge, when the powers are turned on, whether a response signal with respect to a check signal for checking whether the different power supply unit is connected in a rear stage is input from the different power supply unit in the rear stage, andthe control unit is configured to control, when the response is not input, the powers to sequentially turn on the plurality of processing units connected to the power supply unit, and control, when the response signal is input, the powers to sequentially turn on the plurality of processing units connected to the power supply unit after a startup completion signal is input, the startup completion signal indicating that the startup of the different plurality of processing units connected to the different power supply unit in the rear stage is completed.
