There is provided a file sharing system which allows accessing a memory that stores failure information and using the failure information even in a case where a CPU is shut down. When a failure occurs on a substrate, a control circuit on the substrate detects the failure and stores the information on the failure to an NVRAM. In a normal case, an OS loads the failure information and transmits it to a PC for maintenance. Upon shut down of the OS, a BMC loads the failure information from the NVRAM according to an instruction from the PC for maintenance. If an operator operates a manual switch upon power shut down, the BMC operates with the power supply from a battery, and the failure information is obtained from the NVRAM.
