A communication section of computer peripheral equipment connected to a network is disconnected from the network. A current network setup value set in the communication section is saved in a first storage section. A fixed network setup value stored in a second storage section is set in the communication section. By using the fixed network setup value, a maintenance operator, for example, uses a computer having an installed maintenance tool to communicate with the communication section, and thus performs maintenance of the peripheral equipment.
