PURPOSE:To facilitate the analysis of the cause of a fault by reading unit package information and system leading condition information in respective service processors so as to reset at the time of applying a power source and at the time of resetting and reading both information with the command of the processor so as to compare them at the time of diagnosing. CONSTITUTION:Duplicated processor sub systems are respectively constituted with service processors 104 and 114 and processors 102 and 112, etc., and the processor 104 and 114 are connected with a bus 120 so as to set unit package and system startup condition information 107 and 117 corresponding to working condition in a processor module. And at the time of applying the power source and at the time of resetting a system, the processors 104 and 114 read the information 107 and 117 and keep them inside and the normal system processor 102 or 112 outputs its own system information read command and then outputs another system command to its own system processors 104 and 114 to compare received information in both systems with the processors 102 or 112.
