Abstract: A method for remotely triggered reset of a baseboard management controller (BMC) of a computer system is disclosed. The computer system includes a first computer node, a second computer node and a control unit. The method includes: (A) receiving, by a first BMC of the first computer node, from a computer device and via a network, a reset command which indicates that reset of a second BMC of the second computer node should be triggered; (B) transmitting, by the first BMC and to the control unit, a control signal that corresponds to the reset command; and (C) transmitting, by the control unit and to the second BMC, a reset signal that corresponds to the control signal, so as to trigger reset of the second BMC.

Abstract: A method for data communication within an I2C system is provided. The method includes the steps of: a) generating a communication error code indicative of error status when data transmission from a master module to a slave module via an I2C bus fails; b) determining whether to retransmit the data to the slave module according to the communication error code; c) when the determination made in step c) is affirmative, determining whether a number of times of data retransmission(s) associated with the data reaches a predetermined number; d) when the determination made in step c) is affirmative, resetting the master module; and e) recording a communication error event according to the communication error code after step a).

Abstract: When a baseboard management controller (BMC) is used to control a fan speed of a fan unit of a server by executing a firmware with fan parameter data stored in one temporary storage region, the fan parameter data is updated by receiving fan parameter update data and storing the fan parameter update data in another temporary storage region, and updating the fan parameter data using the fan parameter update data after determining that the received fan parameter update data is valid.

Abstract: A method is for updating an original firmware file of an I/O module which communicates with multiple host-end devices and stores the original firmware file. The method includes: receiving a current-received data packet from one host-end device; when it is determined that the current-received data packet is a first data packet constituting an update file, and that the original firmware file is not undergoing an update process, setting a status flag to indicate that the original firmware file is undergoing an update process, storing the current-received data packet; and repeating the previous steps when it is determined that the current-received data packet is not a last one data packet constituting the update file.

Abstract: A system includes a bus, multiple BMCs, and a control unit. Each BMC generates heartbeat signals and acquire operation data associated with a to-be-monitored unit once being initiated, and operates in one of a master mode and a slave mode according to a corresponding decision signal. One of the BMCs which operates in the master mode is configured to receive via the bus the operation data from the rest of the BMCs which operate(s) in the slave mode for monitoring the to-be-monitored unit. The control unit is configured to, according to the heartbeat signals, generate the corresponding decision signals for controlling a first normally operating one of the BMCs to operate in the master mode and the rest of the BMCs to operate in the slave mode.
