Abstract

The invention discloses a method, system, device and storage medium for detecting the connectivity of the entire link of the cable. The method includes: setting first resistors with the same resistance value at both ends of each cable connecting the main board and the sub-board, And connect one end of the first resistor to the cable detection signal, and the other end to ground; connect the second resistor in series on the cable detection signal of the main board, and connect the third resistor of the same resistance value in series on the cable detection signal of each sub-board; Based on the switch switching chip, the second resistor is connected to each cable in turn, and whether the cable detection signal of each cable is normal; and in response to the cable detection signal of each cable being normal, determine that the cable is all The connectivity of the link is normal. The invention detects the connectivity of the whole link of the cable by using the low-cost resistor, which not only reduces the cost, but also saves precious I2C resources, and can locate the abnormal position according to the voltage value.

Description

A method, system, device and medium for detecting full-link connectivity of cables technical field

[0001] The present invention relates to the field of cables, and more particularly, to a method and system for detecting the connectivity of a full link of a cable. systems, computer equipment and readable media. Background technique In the field of server technology, the scale of data such as storage, computing, and communication continues to expand, and in traditional x86 server racks In order to facilitate the expansion of storage and computing resources, the hard disk backplane and GPU (Graphics Processing) are often connected through cables. Unit, graphics processor) board, etc., in order to match different configurations according to different needs, play the role of flexible configuration and easy expansion use. For example, in the whole cabinet server, add storage nodes for extended storage functions; add GPU nodes for extended computing functions Wait. The ...
