Serial port information transmission method, single board device and common-used single board

Abstract

The invention aims at providing a serial port information transmission method, a single board device and a common-used single board. The single board device at least comprises a lower computer module and a central processor. The method comprises steps: the lower computer module receives a first message in an IPMI format carrying the serial port information sent by an upper computer module via an electromechanical management channel; the lower computer module converts the first message to a second message in a universal serial port message format carrying the serial port information; and the lower computer module sends the second message to the central processor via a second serial port, and the central processor executes corresponding processing according to the serial port information in the second message. The existing electromechanical management control method and the channel are used, and transmission of the central processor serial port information of all slave nodes is controlled at the electromechanical management control node.

Description

technical field [0001] The invention relates to the field of frame-type telecommunication equipment with electromechanical management, in particular to a serial port information transmission method, a single-board device and a common single-board. Background technique [0002] For traditional box-type telecom equipment, such as box-type WDM equipment, switching and routing equipment, etc., the single board needs to provide serial ports to input and output serial port information, output events, alarms, input commands, debugging commands and other information. However, when designing and manufacturing single-board equipment, it is necessary to consider issues such as board chip layout integration, panel design, etc., so it may not be possible to provide panel serial ports, and the internal interfaces of the single board may not be able to provide standard interfaces, or in the production unit. This interface is not soldered when the board is installed. In addition, for secur...

Problems solved by technology

However, when designing and manufacturing single-board equipment, it is necessary to consider issues such as board chip layout integration, panel design, etc., so it may not be possible to provide panel serial ports, and the internal interfaces of the single board may not be able to provide standard interfaces, or in the production unit. This interface is not soldered when the board is installed

In addition, for security reasons, the serial port information cannot be exposed to ordinary users after the device is installed.

This will cause some troubles for engineering installation personnel and equipment maintenance personnel, and they cannot use the serial port to log in to the single board to collect the status information of the single board operation.

[0003] If the existing serial port channel is used to debug and control the single-board device, the maintenance personnel can only log in to a specific single-board device for operation, so it cannot be used in most engineering site environments
