Problems solved by technology

When the BMC firmware is abnormal and the BMC needs to be debugged, the system serial port of the traditional server is not connected to the debug (Debug) serial port of the BMC, and the Debug information of the BMC cannot be viewed from the system, but usually through the Debug port installed on the motherboard Connect the data cable and the Debug card, and check the abnormal cause of the BMC firmware on the Debug card
However, such an operation requires dismantling the server case, and the use of external data cables and Debug cards, making on-site operation more troublesome

Embodiment Construction

[0016] Please refer to figure 1 , the serial port switching system 16 of the preferred embodiment of the present invention runs in a baseboard management controller (Baseboard Management Controller, BMC) 10 of a server 1 . In this embodiment, the server 1 further includes a super input-output (Super Input Output, SIO) chip 20 , a basic input-output system (Basic Input-Output System, BIOS) 30 and a multiplexer (Multiplexer, MUX) 40 . The BMC 10 includes a SOL (Serial over LAN, serial communication over LAN) serial port 102 and a Debug (debug) 104 serial port. The SIO chip 20 includes a system serial port 22 for sending and receiving commands and information for the server system. The system serial port 22 is connected to the SOL serial port 102 and the Debug serial port 104 of the BMC10 through the MUX40, and the BIOS30 controls the MUX40 so that the system serial port 22 is selectively connected to the SOL serial port 102 or the Debug serial port 104 of the BMC10 to debug at ...

Abstract

A serial switching system is applied to a baseboard management controller (BMC) of a server. BMC firmware is stored in the BMC. The BMC comprises a serial over LAN (SOL) and a Debug serial and is connected to a basic input-output system (BIOS). The server further comprises a multiplexer (MUX), and the MUX is respectively connected to the BIOS, and the SOL and the Debug serial of the BMC. The serial switching system comprises a setting module, a control module, a receiving module and a sending module, wherein the setting module is used for setting a menu option in the BIOS; the control module is used for sending control signals to the MUX through the BIOS and sends the control signals the MUX so as to control communication conditions of the MUX; the receiving module is used for receiving commands of a server system from the SOL or the Debug serial; and the sending module is used for sending information of the BMC firmware to the SOL or the Debug serial so as to feed the information back to the server system. The invention further provides the server with the serial switching system and a serial switching method.

Description

technical field [0001] The invention relates to a serial port switching technology, in particular to a serial port switching system for switching a server system serial port and a BMC serial port, a server with the serial port switching system and a serial port switching method using the serial port switching system. Background technique [0002] In the server system, the baseboard management controller (BMC) is responsible for hardware platform management, is the core of the intelligent platform management interface (IPMI), and is an important component in the server system. The firmware of the BMC is used to drive the BMC to realize the functions of the BMC. When the BMC firmware is abnormal and the BMC needs to be debugged, the system serial port of the traditional server is not connected to the debug (Debug) serial port of the BMC, and the Debug information of the BMC cannot be viewed from the system, but usually through the Debug port installed on the motherboard Conne...
