Interface multiplexing circuit, method, device, equipment and medium

The invention discloses an interface multiplexing circuit, method and device, equipment and a medium, and relates to the technical field of servers. The BMC and the PCIe Switch of the circuit are both connected to the same RJ45 network port. At the moment, the on state or the off state from the first input end to the third input end of the data selector is controlled through the obtained first GPIO signal of the BMC and the obtained second GPIO signal of the PCIe Switch, so that PCIe Switch troubleshooting or firmware upgrading is carried out. An original scheme that the BMC and the PCIe Switch are both correspondingly connected with one RJ45 network port is replaced by a scheme that the BMC and the PCIe Switch are both connected with one RJ45 network port, so that PCIe Switch equipment troubleshooting and firmware upgrading are simplified on the premise of not additionally occupying the space of a panel. 本申请公开一种接口复用电路、方法、装置、设备及介质，涉及服务器技术领域。该电路的BMC和PCIe Switch均连接于同一个RJ45网口上。此时，通过获取到的BMC的第一GPIO信号和PCIe Switch的第
