Patent ID: 7366950

Claim:
A network connectable equipment comprising: a processing unit; a single power supply module; a communication module for connecting with a network; a power supply line for connecting said power supply module to said processing unit; and a power control line for connecting said communication module and said power supply module, wherein said single power supply module stops supplying electric power to the network connectable equipment other than said communication module if the network connectable equipment is in a power-off state, wherein if said communication module receives frame data via said network, then said communication module determines whether the frame data is addressed to the network connectable equipment or not, and issues a power-on request to the single power supply module if the frame data is determined to be addressed to the network connectable equipment and the network connectable equipment is in the power-off state, wherein the single power supply module receives said power-on request via said power control line, supplies power to said processing unit via said power supply line based on said power-on request to cause the network connectable equipment to be in a power-on state, and does not supply power to said processing unit via said power supply line after said processing unit computer processing related to the frame data to cause the network connectable equipment to be in the power-off state, and wherein said communication module receives frame data via said network, determines whether the frame data is addressed to the network connectable equipment or not, and transmits notification to said power supply module prior to transmitting the power-on request to said processing unit if the frame data is determined as being addressed to the network connectable equipment and the network connectable equipment is in the power-off state.
