A data processing apparatus includes a power-source controller, a data processing device, a physical-layer section, a communication controller, and a state controller. The power-source controller controls a first power-source setting and a second power-source setting. The second power-source setting causes less electric power consumption than the first power-source setting. The communication controller performs the communication with the data processing device through a predetermined communication path and the physical-layer section under the first power-source setting. The communication controller stops the communication with the data processing device through the communication path and the physical-layer section under the second power-source setting. The state controller maintains the second communication state with respect to the data processing device side of the communication path while electric power supply to the physical-layer section is reduced under the second power-source setting.

Data processing apparatus

One or more embodiments may relate to an information processing device connectable to a network and including interfaces in which network identification numbers can be set. The information processing device may include: a network connection determination processor that determines whether or not first and second interfaces of the interfaces are connected on a same network; an identification number setting processor that sets, when the first and second interfaces are connected on the same network, a network identification number of one of the first and second interfaces in the other interface; and a stop-startup processor that stops the one of the first and second interfaces.

Information processing device including first and second network interfaces

An image forming apparatus includes a power supply part that supplies electronic power in two different power modes (first and second modes), a communication part that includes a transmitting and receiving part that receives a network packet in the both modes, and a determination part that stores filter information and determines whether or not the network packet matches one of filter settings, a determination control part that performs a rewrite operation to repeatedly rewrite the filter information while running in the second mode, a power supply control part that transits the power mode of the power supply part from the second mode to the first mode based on a determination result of the determination part, a packet transmitting and receiving part that receives the network packet supplied from the transmitting and receiving part in the first mode and stops an operation of itself in the second mode, and an image forming part stops an operation of itself in the second mode.
