Server board card device, control method thereof and related components

Abstract

The invention discloses a server board card device and a control method and related components thereof, the server board card device comprises a mainboard, a board card comprising a divider resistor, and a cable connected with the mainboard through a first plug connector and connected with the board card through a second plug connector, and the cable comprises a power line, a grounding line, a detection line and a plurality of thermistors; and the BMC in the mainboard obtains the electrical parameters of the thermistors through the detection line, and judges whether the first plug connector and the second plug connector are abnormal or not according to the electrical parameters. The detection line for detecting the state and the thermistors are arranged in the cable, the divider resistor is arranged in the board card, the mainboard BMC can rapidly know the state of the first plug connector and the second plug connector through the thermistors, the efficiency and the accuracy are far higher than those of the prior art, and the electrical parameters have higher reference value.

Description

Technical field [0001] The present invention relates to the field of server hardware, and more particularly to a server board device and a control method thereof, related components. Background technique [0002] At present, with the development of big data services, the power consumption of components such as GPU (Graphics Processing Unit, Show chip), NIC, fan, etc., the overall power consumption of the server is getting bigger and larger, in the case of the server voltage constant The current carrying the board between the boards carrying these components is getting bigger and bigger. Use a cable connection between different boards, however, there is a plug and wear between the cable plug and the connector, inserted units, existence of foreign matter, plug deformation, aging, etc., there is a poor contact, the contact resistance is too large Even the hazard of the circuit, the broken circuit, may also cause ablation, thermal change, and even melt burns due to the abnormality of...

AI Technical Summary

Problems solved by technology

Different boards are connected by cables, but there are plugging and unplugging wear between the cable plug and the connector, improper plugging and unplugging, foreign objects, plug deformation, aging, etc., poor contact and excessive contact resistance , or even the hidden danger of short circuit and open circuit, and may also cause ablation, thermal deformation, or even melting and burning problems due to abnormal temperature rise of connectors or cables

[0003] In order to solve the above problems, some workers use the temperature sensor near the board socket to detect the temperature of the connector, and use the board chip to monitor the temperature, but Due to the distance and space, the sensor cannot accurately and timely perceive the state changes of the connectors, and the board chip cannot handle abnormal situations in time
