Abstract

PURPOSE:To minimize the inversion of a power supply sequence by transmitting simultaneously the cut-off signals to all power supply units through a power supply controller when an alarm of the power supply unit is produced. CONSTITUTION:A power supply device of a computer system, etc. is provided with power supply units PWR1-4 and a power supply controller UPC. The on/off of the power supply of each unit PWR is controlled according to a sequence set previously by the controller UPC. Thus for the normal on/off of the power supply command signals are transmitted successively to the units PWR1 PWR2... PWR4 from the controller UPC. If an alarm is produced at the unit PWR2, for example, the controller UPC transmits the cut-off command signals all at once to each unit PWR. Thus the inversion of a power supply sequence can be minimized as shown in a figure.
