CONSTITUTION: When abnormality occurs, at least one of environmental sensors 19W25 detects the abnormality and informs it to an environmental abnormality monitoring circuit 16. The environmental abnormality monitoring circuit 16 outputs an alarm to the outside with regard to various abnormalities detected by the sensor, and also transfers the abnormality to a controlling circuit 15. The control device 15 outputs only an alarm in case when each abnormality is decided to be slight, generates a system freezing processing request to a computer system in case when it is decided to be serious, and generates a cut-off request of all power supply modules to a power supply control device 17 after a constant interval of time. When the abnormality is released, the control circuit 15 generates a system restart request to the power supply controlling circuit 17 and the computer, and reloads them to a state before the abnormality is generated.
