Abstract: A method for switching a shared network protocol of a baseboard management controller comprises: determining whether a mainboard is connected with an external network card by a baseboard management controller; determining whether an external network card network port of the external network card is connected with a network cable by the baseboard management controller when the mainboard is connected with the external network card; connecting a physical link of a shared network protocol of the baseboard management controller with the external network card network port when the external network card network port is connected with the network cable; and connecting the physical link of the shared network protocol of the baseboard management controller with a mainboard network port of the mainboard when the external network card network port is not connected with the network cable. As a result, the shared network protocol can be maintained in normal operation.

Abstract: A method for managing two baseboard management controllers comprises connecting to a first baseboard management controller, sending an instruction to the first baseboard management controller, determining whether the instruction comprises a bridge parameter, when the instruction comprises the bridge parameter, sending the instruction to a second baseboard management controller through a bus, generating a response signal by the second baseboard management controller, and receiving the response signal by the first baseboard management controller and sending the response signal to an administration interface; otherwise, executing a corresponding operation according to the instruction by the first baseboard management controller and sending an operation result to the administration interface.

Abstract: A method of periodically recording for events is disclosed. The method includes the following steps: accessing a register of a power supply by a baseboard management controller to obtain a message related to the power supply; confirming a logical sensor status of the power supply according to the message by the baseboard management controller so as to determine whether a predicted failure status of the power supply is detected, and monitoring a predetermined logical variable by the baseboard management controller; generating an event log when the predicted failure status of the power supply is detected by the baseboard management controller; performing a timing task selectively according to a result of monitoring related to the predetermined logical variable by the baseboard management controller so as to determine whether to generate a control command; generating another event log according to the control command by the baseboard management controller.

Abstract: A monitoring server method includes the following steps. First, the baseboard management controller (BMC) receives the running status information of a system device transferred by the system management software. Then, the BMC determines whether or not the system device is operated in a normal state. When the system device is operated in an unusual state, the virtual sensor data record in the sensor data recorder is set in an abnormal state by the BMC. Then, the BMC generates an event according to the abnormal state to trigger a platform event filter (PEF) of the BMC to issue a warning signal to a remote management host.
