Server fault offline diagnosis device and method

Abstract

The invention provides a server fault offline diagnosis device and method, and the device comprises a control chip, an input pin of the control chip is connected with a substrate management controller, the substrate management controller inputs a fault lamp control signal to the control chip, and the fault lamp control signal comprises a fault lamp on-off control scheme; an output pin of the control chip is connected with the fault lamp; the control chip comprises a first power supply pin and a second power supply pin, the first power supply pin is connected with a server mainboard, and the second power supply pin is connected with an offline power supply; the server mainboard and the off-line power supply are electrically connected with the fault lamp; and the control chip comprises a storage module, and the storage module stores the fault lamp on-off control scheme. According to the invention, offline debug can be conveniently carried out when the high-density server goes wrong. The problem that the post information of the BIOS cannot be analyzed due to the fact that other board cards in the server block the fault lamp due to too complex configuration is avoided.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a server fault offline diagnosis device and method. Background technique [0002] Due to the development of hardware technology and the diversification of customer needs, the functions and configurations that servers can implement are becoming more and more complex, so the requirements for server hardware design and software and hardware interaction are also getting higher and higher. More complex and sophisticated design brings higher performance, but also increases the probability of problems when the server is running. Downtime is a common type of problem in server testing. There are various reasons for downtime, including software and hardware reasons. Therefore, when a downtime occurs, it is necessary to obtain server information as much as possible without destroying the phenomenon, such as hardware configuration, firmware version, BIOS and BMC logs, etc. The ...

AI Technical Summary

Problems solved by technology

However, for some high-density servers, especially 1U servers, when the server is fully configured, the fault light on the motherboard is often blocked by other boards in the case, and the state of the fault light cannot be seen only by opening the case cover

Since most boards cannot be disassembled when the server is powered on, in many cases the on-site postcode information can only be discarded, and can only be obtained by reproducing the bug later.
