Abstract: An example computing system includes a baseboard management controller (BMC), a motherboard, and a daughterboard communicatively coupled to the motherboard. The BMC includes a serial interface. The daughterboard includes a universal asynchronous receiver/transmitter (UART) terminal, a bridging chip, and a microcontroller communicatively coupled to the BMC via the bridging chip. The BMC establishes a serial connection, through the serial interface and the UART terminal, with the microcontroller.

Abstract: Example implementations relate to system and method of managing transitioning of a computing system to a power-on state from a standby-power state. The computing system includes a manageability controller, an initialization controller, an auxiliary device, and a processor. In such examples, the manageability controller may first determine an initialization status of the auxiliary device from a data corresponding to the auxiliary device, when the computing system is transitioning from the standby-power state to the power-on state. In one or more examples, the initialization status may include the auxiliary device in an initialized stage or a non-initialized stage. Later, the manageability controller may direct the initialization controller to delay the transitioning of the computing system from the standby-power state to the power-on state, in response to determining that the initialization status of the auxiliary device is in the non-initialized stage.
