ABSTRACT:
A distributed power supply is incorporated in a device including a plurality of PCB. An on-board power supply is provided in the distributed power supply. The on-board power supply individually supplies a secondary power to each PCB using a primary power. Each PCB includes a primary power supply monitoring circuit, a PCB internal power supply monitoring circuit, and a pulse generation circuit. The primary power supply circuit detects an abnormality in the voltage of in the primary power supplied to the on-board power supply. The PCB internal power supply monitoring circuit restarts the PCB when the abnormality is detected. The pulse generation circuit transmits a restart signal to the other PCBs in the device.
