Problems solved by technology

However, this design has a defect that when customers have BMC-related problems, BMC designers often use BMC serial port information when analyzing problems. The machine cover often requires the server to be shut down, which is not allowed for some user applications that cannot be shut down

Embodiment

[0024] Such as figure 2 As shown, this embodiment provides a server serial port output device, including: an existing baseboard management controller BMC, a two-to-one switching chip, a serial port output switching button, and a DB9 serial port connector, wherein:

[0025] The input end of the LPC (Low Pin Count, low pin count) decoding module of described BMC is connected with the LPC bus of server chipset, and the output end output system serial port information of described LPC decoding module;

[0026] Wherein, the server chipset can be a Southbridge (Platform Controller Hub, PCH) chip, and the LPC bus (transmitting LPC signals) of the Southbridge is connected to the LPC decoding module of the BMC. After being processed by the LPC decoding module, it is converted into an RS232 signal and passed through the BMC Output; the serial port information of BMC is output directly through BMC inside BMC, output RS232 signal;

[0027] Add a two-to-one switching chip on the peripher...

Abstract

The invention discloses a server serial port output method and a server serial port output device. The device comprises a BMC (Baseboard Management Controller), an either-or switching chip, a serial port output switching press button and a DB9 serial port connector, wherein the input end of an LPC (Low Pin Count) decoding module of the BMC is connected with an LPC bus of a server chip group; the output end of the LPC decoding module outputs system serial port information; the output end of the LPC decoding module and the serial port output end of the BMC are respectively connected to two input ends of the either-or switching chip; the output end of the either-or switching chip is connected with the DB9 serial port connector; the serial port output switching press button is connected to the switching control end of the either-or switching chip; and the either-or switching chip is controlled to be switched between the two input ends through control signals. The server serial port output method and the server serial port output device have the advantages that the free switching between a system serial port and a BMC serial port for output can be realized only through the DB9 serial port connector; the requirements of development personnel on the system serial port and BMC serial port information are met; and the mainboard design is also simplified.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and a device for server serial port output. Background technique [0002] In the server system, the output of the system serial port information can let designers and users clearly understand the state of the server during the boot process. The problem of the cause of the failure. Similarly, the server BMC (Baseboard Management Controller, Baseboard Management Controller) is the most important management component of the server. When the BMC fails to start, the serial port information output by the BMC becomes the primary reference information for solving the problem. [0003] Such as figure 1 As shown, two DB9 connectors are used in the traditional server design, one is used as the system serial port output, and the other is used as the BMC serial port output; the south bridge PCH is connected to the Super IO chip, and the system serial port The information is output to one ...
