PURPOSE:To prevent secured fault information destroyed and to clear the cause of a fault in a short time by prohibiting a start-up request from a remote operating terminal based on the state of a maintenance switch. CONSTITUTION:A maintenance mode switch 4 outputs the instructions of a maintenance job execution mode and an on-line job execution mode to a computer system. When the maintenance switch 4 is set at the maintenance job execution mode, on-line job start processing by start-up data from the remote operating terminal 1 is prohibited with an execution control part 6. In such a way, fault analyis can be performed without affecting on the fault information even while a maintenance job is performed, and much time is not required in the clearing of the cause. |
