Abstract
PURPOSE:To eliminate a hung-up condition by providing a power source connection-disconnection processing means which not only controls, to turn off, the power source of a first data processor and a second data processor but also controls, to turn on, the power source of a sub-system data processor when the recovery of a main-system data processor is failed. CONSTITUTION:A power source disconnection processing part 10 is provided at a supervising device 4. When a main-system 1 executes a recovery, the recovery is failed, and the operation of a sub-system 2 is also failed, the power source connection-disconnection processing part 10 disconnects the power source of the main-system 1 and the sub-system 2. Thereafter, the power source of the sub-system 2 is inputted. Thus, when the hung-up condition is generated at the time of a switching from the main-system to the sub-system, the power source of both the systems can be forcibly disconnected by a supervising device 4, and the hung-up condition can be eliminated. Thereafter, by inputting the power source of the sub-system, it can be raised as the main-system.
