Claim:
1. A method for setting network information in a communication device, the method comprising: communicating, by a first communication device, with an intended reception device being a second communication device based on first setting information stored in a first storage unit of the first communication device; transmitting, by the first communication device, the first setting information to the second communication device; storing, by the second communication device, the first setting information received from the first communication device in a second storage unit; transmitting upon startup, by the first communication device, when an initial value is stored in the first storage unit prior to startup of the first communication device, a request signal to the second communication device after first hardware of the first communication device is replaced; receiving, by the first communication device, the first setting information stored in the second storage unit from the second communication device after the first hardware is replaced; and storing, by the first communication device, the first setting information received from the second communication device in the first storage unit of the first communication device by replacing the initial value, after the first hardware is replaced; wherein the first communication device is connected to a third communication device different from the second communication device, the first communication device communicates with the second communication device and the third communication device based on the first setting information stored in the first storage unit, the second communication device is connected to a fourth communication device different from the first communication device, the second communication device communicates with the first communication device and the fourth communication device, the first communication device sets for the first communication device a first address based on the initial value to transmit the request signal to the second communication device when the initial value is stored in the first storage unit upon startup of the first communication device, the second communication device sets for the second communication device, upon receiving the request signal from the first communication device, a second address available for communication with the first communication device for which the first address has been set, and the second communication device transmits the first setting information stored in the second storage unit to the first communication device.
