Patent ID: 8423699

Claim:
An information processing apparatus comprising: a system control apparatus connected to each of a plurality of control circuits via a first signal line; a plurality of control circuits each of which is connected to other control circuits other than an own control circuit via second signal lines; a control signal transmitting unit provided in the system control apparatus that transmits a control signal to the plurality of control circuits via the first signal line, the control signal including a command performing a control setting on the other control circuits other than the own control circuit or to all of the plurality of control circuits; a signal receiving unit provided in each of the plurality of control circuits that receives the control signal transmitted from the control signal transmitting unit of the system control apparatus via the first signal line; a signal transfer unit provided in each of the plurality of control circuits that transfers the command included in the control signal received by the signal receiving unit to a control circuit that is a control setting target via the second signal lines; a control setting unit provided in each of the plurality of control circuits that performs the control setting on the own control circuit according to a command included in the control signal received by the signal receiving unit or a command transferred from the other control circuits other than the own control circuit; an abnormality determining unit provided in the system control apparatus that determines whether an abnormality occurs in the plurality of control circuits; a packet generating unit provided in each of the plurality of control circuits that generates packet data including the command included in the control signal transmitted from the control signal transmitting unit of the system control apparatus; and a command converting unit provided in each of the plurality of control circuits that converts the packet data transferred from the other control circuits other than the own control circuit into a command used for the control setting for the own control circuit, and wherein the control signal transmitting unit transmits to the other control circuits other than the own control circuit via the first signal line, a control signal including a command performing the control setting on a control circuit in which the abnormality occurs, and wherein signal transfer units included in the other control circuits transfer, via the second signal lines, the command included in the control signal transmitted from the control signal transmitting unit of the system control apparatus to the control circuit in which the abnormality occurs, wherein the first signal line is a serial bus, and the second signal lines are data buses for packet data to be processed in the plurality of control circuits, and wherein the signal transfer unit transfers, via the second signal lines, the packet data generated by the packet generating unit to the control circuit in which the abnormality occurs.
