The external CPU is provided outside the switch IC and connected to the switch IC, and has higher information processing capability than the internal CPU. The external CPU can perform a transfer order process of ordering to transfer information to the communication device and perform a security process of securing the security of the information to be transferred when the transfer order process is performed. The internal CPU monitors the operation of the external CPU and when the external CPU is abnormal, performs the transfer order process instead of the external CPU.
