  • Publication number: 20210109588
    Abstract: In accordance with one embodiment, a fan controller operates in a standard mode when main power is provided to the power supply unit in which speed of the fan is controlled in response to a primary pulse width modulation (PWM) signal from a power controller. A loss of the main power to the power supply unit may be detected at a logic circuit, which provides a secondary PWM signal to the fan controller in response to the loss of the main power. In certain embodiments, the fan controller is operated in a power loss mode in response to the secondary PWM signal to direct the speed of the fan to a low-power consumption target speed.

    Abstract: An information handling system includes a device and a baseboard management controller. The device is configured to communicate with a processor of the information handling system. The baseboard management controller is configured to communicate with the device via an in-band communication channel. The baseboard management controller determines whether data is received from the device via an in-band communication channel, and determines whether the baseboard management controller may communicate with the device via an out-of-band communication channel. In response to the data not being received and the baseboard management controller not able to communicate with the device, the baseboard management controller detects a failure of the device. In response to the detection of the failure of the device, the baseboard management controller isolates the device.
