Abstract
A computing device includes a thermal excursion detection unit and a power supply unit. The thermal excursion detection unit is configured to monitor a temperature of an internal volume of the computing device and to control the operation of the power supply unit. The power supply unit is configured to provide power to hardware components in the computing device and the power supply unit only provides power to the hardware components when the thermal excursion detection unit permits.
Claims16
A computing device, comprising:
- a thermal excursion detection unit, wherein the thermal excursion detection unit is configured to monitor a temperature of an internal volume of the computing device and to control the operation of a power supply unit;
- the power supply unit is configured to provide power to hardware components in the computing device, wherein the power supply unit only provides power to the hardware components when the thermal excursion detection unit permits;
- and
- a baseboard management controller, wherein the thermal excursion detection unit executes on the baseboard management controller, wherein the power supply unit comprises the thermal excursion detection unit, wherein the power supply unit provides power to the baseboard management controller, wherein the hardware components do not comprise the baseboard management controller.
A method for thermal excursion monitor and control of an internal volume of a computing device, comprising:
- detecting a current temperature of an internal volume of a computing device via a temperature sensor that is operatively connected to a hardware component of the computing device;
- making a determination, using the detected current temperature, that the current temperature of the internal volume of the computing device is below a threshold;
- and
- in response to the determination:
- preventing a power supply unit to provide power to hardware components in the computing device and stopping operation of the computing device, wherein the power supply unit comprises a thermal excursion detection unit,
- wherein, in order to prevent a damage to each of the hardware components, the thermal excursion detection unit instructs the power supply unit not to provide power to the hardware components comprising at least the thermal excursion detection unit and the temperature sensor, and
- wherein, when the power supply unit does not provide power to the thermal excursion detection unit and the temperature sensor, a battery of the computing device provides power to the thermal excursion detection unit and the temperature sensor.
An information handling system, comprising:
- a cabinet housing a plurality of computing devices;
- the plurality of computing devices, wherein each of the computing devices comprises:
- a thermal excursion detection unit, wherein the thermal excursion detection unit is configured to monitor a temperature of an internal volume of the computing device and to control the operation of a power supply unit;
- a temperature sensor operatively connected to the thermal excursion detection unit, wherein the thermal excursion detection unit monitors the temperature of the internal volume of the computing device using the temperature sensor;
- a battery, wherein the battery provides power to the thermal excursion detection unit and the temperature sensor, wherein the power supply unit does not provide power to the thermal excursion detection unit and the temperature sensor;
- and
- the power supply unit is configured to provide power to hardware components in the computing device, wherein the power supply unit only provides power to the hardware components when the thermal excursion detection unit permits.
