A communication apparatus includes a communication unit, a power supply unit, a temperature monitoring unit, and a control unit. The communication unit communicates with an additional apparatus. The power supply unit supplies power to components mounted in the communication apparatus. The temperature monitoring unit monitors a temperature in the communication apparatus to detect presence or absence of a temperature abnormality. In a case where the temperature monitoring unit detects the temperature abnormality, the control unit performs power supply stop processing of stopping the power supply from the power supply unit to at least some of the components. Furthermore, the control unit stops or decreases communication of the communication unit in a case where the temperature monitoring unit detects the temperature abnormality.

Communication apparatus and temperature monitoring method

A communication apparatus includes a plurality of devices, each of the plurality of devices includes a monitoring unit configured to monitor at least one other device to detect an error that has occurred in the other device, and each of the plurality of devices is monitored by at least one other device.
