Embodiment Construction

[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...

Abstract

The invention discloses a server physical serial port sharing system and serial port sharing method, and relates to the technical field of servers. The switching operation of a system serial port anda debugging serial port can be carried out through a serial port input command in a server debugging process; BMC serial port information is obtained without opening a case cover plate; a scheme simple to realize and convenient to use is provided for sharing a serial communication port by the system serial port and the debugging serial port of a server; and therefore, the debugging efficiency is greatly improved, the manual operation is reduced, and the later maintenance is more convenient.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a server physical serial port sharing system and a serial port sharing method. Background technique [0002] The server system serial port outputs the system information during the server startup process, which is convenient for BIOS software engineers to understand the server startup status and locate and solve server abnormalities. [0003] The server BMC debugging serial port outputs BMC debugging information, which is convenient for BMC software engineers to understand the status information of BMC and meet the debugging needs. [0004] The BMC debugging serial port is not open to users, so in the design of the server, the external debugging interface is generally not reserved for the BMC on the front and rear panels, and the BMC debugging serial port is only reserved in the chassis. [0005] In the past server system debugging process, it is often necessary to open the chas...
