PROBLEM TO BE SOLVED: To switch 1st and 2nd connections to 3rd and 2nd connections without initializing a 2nd computer by providing power circuits which are attached to 1st and 3rd computers, also receive a signal from a failure detecting circuit of the other computer and stop the function of the other computer after starting their own computers. SOLUTION: The case where a failure occurs in a 1st computer C1, information from the computer C1 to a 2nd computer C2 is stopped and a 3rd computer C3 is changed to a connection to the computer C2 is considered. When a failure occurs in the computer C1, the computer C1 sends an off command 12a to the computer C3. With this, power supply is inputted by a power circuit 14 of the computer C3, and after the computer C3 is started, it sends an off command 13b that stops the computer C1 to the computer C1 and stops its function. In this way, the connection of the computers C3 and C2 is switched without initializing the computer C2. |
