System and method capable of remotely controlling working condition of server cooling fan

Abstract

The invention provides a system capable of remotely controlling the working condition of a server cooling fan. The system capable of remotely controlling the working condition of the server cooling fan comprises the server cooling fan and remote control equipment which are located on a server main board. The remote control equipment comprises a receiving and dispatching module, a processor, a display window, an option key, an on-off key and a speed-adjusting key. The receiving and dispatching module is used for communicating with the fan by the server main board; the processor communicates with the receiving and dispatching module and stores fan rotating speed signals from the fan in a register of the processor; the display window is used for displaying the fan rotating speed signals fromthe register; and the option key, the on-off key and the speed-adjusting key are used for sending controlling signals to the fan through the processor and through the receiving and dispatching modulecorrespondingly to perform selection, turning on and off and speed adjustment on the fan. According to the system capable of remotely controlling the working condition of the server cooling fan, through a remote infrared controlling method, the working condition of the fan is monitored, the fan can be controlled in real time, circuits can be protected, and the losses can be further reduced.

Description

technical field [0001] The present invention generally relates to the computer field, and more specifically, relates to a system and method for remotely controlling the working state of a cooling fan of a server. Background technique [0002] In the field of current server equipment, the cooling work of the whole server is almost all done by the fan, and the fan achieves the purpose of cooling by accelerating the air flow inside the server chassis. For fan control, the current common method is to control the fan speed through BMC Web. Through the control of the fan speed on the BMC (Baseboard Management Controller, baseboard management controller) interface, you can choose to manually control the speed or automatically control the speed. Manual control That is, the fan speed can be modified artificially, while the automatic control means that the system adjusts the fan speed according to the current temperature state of each device, so as to ensure that each device chip can ...

Problems solved by technology

In the actual operation process, it is often necessary to plug and unplug the fan for installation, fixation and maintenance. During the plugging process, the terminals of the cables used to transmit the in-position signal or the terminals of the fan may be damaged due to excessive plugging force. In the cracked state, the damaged fan may stop rotating at this time, or rotate at full speed, while other fans may also rotate at full speed due to the heat dissipation strategy. In this case, the life of the fan will be shortened, and it will cause a lot of noise. In serious cases, the motherboard may be burned due to a short circuit

If you want to quickly locate the faulty fan, you need to connect to BMC Web to view it. This method is very complicated. You must log in to the BMC interface through Ethernet. In case there is no network cable or computer that can connect to the network in the experimental environment, you can If you cannot log in to the BMC, you cannot locate the problematic fan, so a simpler and more efficient way is needed to solve this problem
