System and method for automatically checking connection relation of communication cables

Abstract

The invention belongs to the technical field of cable connection detection, and particularly provides a system and method for automatically checking the connection relation of communication cables, and the system comprises a first device end and a second device end. The first equipment end and the second equipment end are both provided with a plurality of channels; each channel between the first equipment end and the second equipment end is connected by using a cable bundle; the cable bundle connected with each channel comprises a detection signal line; the first equipment end is provided with a management control module; the management control module is connected with the second equipment end; the management control module is also connected with the channel of the first equipment end; and the management control module is used for controlling the level state of the detection signal line of the second equipment end channel, monitoring the level state of the detection signal line of the first equipment end in real time, and distinguishing the cable connection relationship according to the monitoring result. The cable plugging position can be automatically identified, and the problems of wrong plugging position and missing plugging of the cable can be intelligently judged. And the real-time output of a cable interconnection relation table is supported, so that the cable inserted in a wrong position can be corrected conveniently.

Description

technical field [0001] The invention relates to the technical field of cable connection detection, in particular to a system and method for automatically checking the connection relationship of communication cables. Background technique [0002] With the rapid development of AI computing, high-performance computing, and artificial intelligence applications, the wide application of heterogeneous computing devices has been promoted. In order to obtain powerful heterogeneous computing capabilities and scalable performance, CPU computing and GPU computing are usually divided into two independent devices, the server and the GPU BOX, and are connected and communicated using PCIe high-speed cables. [0003] Usually, more high-speed cable bundles are used between the server and the GPU BOX. Each x16 bandwidth needs to use 4 high-speed cable bundles. When the system supports 4 sets of PCIe communication channels with a bandwidth of x16, 16 high-speed cable bundles are required. [...

AI Technical Summary

Problems solved by technology

Mis-insertion of cables in the same group of communication ports, mis-insertion of cross-port positions, missed or improperly inserted cables, etc., will lead to problems such as abnormal PCIe communication bandwidth, inability to communicate, and mismatch between the GPU system serial number and the physical serial number. , is often misjudged as a GPU board function problem, and troubleshooting and clarification will consume more human resources. The present invention provides a system and method for automatically checking the connection relationship of communication cables
