Server physical serial port sharing system and serial port sharing method

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0036] see figure 1 As shown, the embodiment of the present invention provides a server physical serial port sharing system: including a BMC module, a multiplexer, a level shifter and a serial communication port:

[0037] The BMC module includes a system serial port, a debugging serial port and a general interface, and the system serial port, debugging serial port and general interface are respectively connected to the multiplexer;

[0038] The multiplexer is used to switch one of the system serial port and the debugging serial port to the level shifter; the default state of the multiplexer is the state where the system serial port and the level shifter are turned on.

[0039] The level converter is used to realize the level conversion between the multiplexer and the serial communication port; the level converter is used to realize the mutual co
