Abstract

PURPOSE:To prevent unreported fault information from being initialized by reporting fault information to a service processor, and after completing the report, releasing a power ON command. CONSTITUTION:A power supply 4 transmits detailed information 17 relating to power supply abnormality to a power supply controller 2 at the time of receiving a detailed information request command 16 and the controller 2 reports the detailed information 18 to the service processor 1 at the time of receiving the information 17. Then, the controller 1 transmits an interruption permission command 19 to detect the existence of a state change in other power supplies, and when the state change is generated in any power supply out of others, receives an interruption command 8. Thereafter, said procedure is repeated, and after completing the report of information from all the power supplies generating abnormality to the service processor 1, holding is released. Consequently,t he fault information of each power supply can be always reported to the service processor 1.
