PURPOSE:To simplify the constitution of a power supply controller by deciding a service processor which records the information on a power supply fault based on the received operating state. CONSTITUTION:Both service processors 40 and 50 are connected to the logic processors 10 and 20 via diagnosis interfaces respectively. Then one of both devices 40 and 50 is valid in a close connecting operation mode and diagnoses the logic devices 10 and 20. While both processors diagnose both logic devices respectively in a separating operation mode. A power supply controller 60 monitors the overall state of the device power supply via a serial control bus 85 and contains an operating state receiving part 64 which receives the operating state from the service processor, a power supply abnormality information collecting part 63 which collects the power supply abnormality information on plural devices, and a power supply abnormality information transmitting part 62 which transmits the power supply abnormality information based on the operating state. Each of both processors 40 and 50 contains an operation recognizing part 43 which recognizes the present operating state, an operating state transmitting part 45 which transmits the operating state to the controller 60, and a power supply abnormality information receiving part 44 which receives the power supply abnormality information from the device 60. |
