Method and device for checking cable connection between main board and backboard

Abstract

The invention discloses a method and a device for checking cable connection between a main board and a backboard. The method comprises the steps that a baseboard management controller of a main boardissues a cable connection configuration file to a complex logic programmable device of a backboard through an internal integrated circuit bus and stores the cable connection configuration file in a user flash memory of the complex logic programmable device; the complex logic programmable device of the backboard reads the cable connection configuration file from the user flash memory when the complex logic programmable device is powered on so as to obtain a configuration connection mode, and accesses a nonvolatile memory to expand the hard disk so as to obtain an actual connection state; and the complex logic programmable device of the backboard compares the configuration connection mode with the actual connection state to generate a cable connection verification result, and feeds back thecable connection verification result to the baseboard management controller for display and output. According to the invention, cable connection errors can be quickly found and processed, the manual inspection cost is reduced, and the maintenance efficiency is improved.

Description

technical field [0001] The present invention relates to the field of assembly, and more specifically, to a method and device for verifying cable connections between main backplanes. Background technique [0002] As the server industry matures, server products emerge in endlessly. However, the mainstream architecture of the server is still the mainboard + backplane design, and the communication between the main backplanes is realized through cable connections. Currently, the connection configuration between the motherboard and the backplane is mainly determined by the type of the backplane. Hard disks are mainly divided into NVME (Non-Volatile Memory Extension) hard disks and SAS / SATA hard disks. For NVME hard drives, the controller end (controller port) is divided into CPU (Central Processing Unit) and PCIESwitch (Peripheral Component Interconnect Expansion Switcher), but each CPU contains 16 PCIE Ports (Peripheral Component Interconnect Expansion Port) , and the PCIE Swi...

AI Technical Summary

Problems solved by technology

What's more, for some configurations that R&D personnel are not familiar with, it takes a long time to find the cable connection problem

At the same time, for the hard disk connected to the PCIE Switch, because the FW (firmware) of the Switch chip itself affects the sorting and lighting of the hard disk, it will be more difficult to find the problem at this time, reducing the efficiency of research and development and testing

[0004] There is currently no effective solution to the problem that cable connection errors in the prior art are difficult to find and deal with and affect work efficiency
