A single main unit manages information on hardware resources and the like of all main units connected to a network in an integrated fashion. A slot management module, a slot control module, and a physical slot/managed slot comparison table are provided between an input/output control module and a slot interface subordinate thereto. The input/output control module accesses the slot interface by using virtual slot identification information. The slot management module refers to the physical slot/managed slot comparison table, converts the virtual slot identification information into physical slot identification information, and accesses a slot control module corresponding to the physical slot identification information obtained by the conversion, thereby realizing a physical access of the input/output control module to the slot interface.
