A board mis-insertion prevention circuit includes a first detection circuit, a second detection circuit, and a control module. The first detection circuit detects whether a board is in a first state and outputs a first detection signal when the board is in the first state. The second detection circuit detects whether the board is in a second state when the board is not in the first state, and outputs a second detection signal when the board is in the second state. The control module receives the first detection signal or the second detection signal and can allow or disconnect a power supply to the board according to the first detection signal or the second detection signal.

Circuit preventing supply of power to board incorrectly or unstably installed, method, and server system

A data center security control module able to connect with motherboards of different platforms such as Intel platform, AMD platform, and Ampere platform includes a baseboard management controller (BMC), a chip selection module, and a control module. The BMC outputs an alarm signal. The chip selection module includes N chip selection units, the chip selection unit outputting alarm signal to an external motherboard which is connected to the data center security control module. The control module obtains information as to motherboard type being Intel platform, or AMD platform, or Ampere platform and outputs a control signal to the chip selection module according to the motherboard type to start the chip selection unit associated with such motherboard type. The application also provides a data center security control module control method.

Baseboard management controller module

The present disclosure provides a log information obtaining system and method. The log information obtaining system includes a baseboard management controller (BMC), a storage device, a first interface, a controller and a first selector. The storage device stores log information of the electronic device. The controller obtains a first signal of the BMC and determines the working state of the BMC, the controller outputs a first selection signal when the working state of the BMC is abnormal. The first selector selects the first output terminal to output the log information received from the first input terminal to the external device. Even if the BMC cannot work normally, it can still obtain the log information of the electronic device and debug the electronic device.
