Abstract: A high-speed serial computer expansion bus circuit topology, comprises: a first signal path connecting between a first interface and a second interface, a second signal path connecting between the first interface and a third interface, a third signal path connecting between the third interface and a fourth interface, a first selector circuit having a first passive element and a second passive element which are respectively disposed in the first signal path and the second signal path, a second selector circuit having a third passive element and a fourth passive element which are respectively disposed in the second signal path and the third signal path. The second signal path is conducted when the first passive element and the second passive element are conducted, the third signal path is conducted when the third passive element and the fourth passive element are conducted.

Abstract: The present disclosure provides a fan management method and system, and a server. The method includes: monitoring working performance of each dual-motor fan in real-time; determining whether the working performance of the dual-motor fan is normal, if the working performance is normal, instructing the dual-motor fan to continue to operate with normal performance; if the working performance is not normal, instructing a single-motor fan that has no abnormality in the dual-motor fan to operate with a preset compensation strategy; the preset compensation strategy is a strategy for performing performance compensation for a single-motor fan that has no abnormality to normal performance of a dual-motor fan. The present disclosure can reduce energy consumption of the server, avoid ineffective waste, and save operating costs. The fan can be prevented from running at a high speed for a long time, and the service life of the fan can be improved.

Abstract: The present disclosure provides a method for automatically optimizing power consumption. The method includes: (S1) a baseboard management controller determines whether system information is correct or not after powered on. If correct, further proceeding the method. If not correct, stopping further proceeding the method. (S2) the baseboard management controller periodically detects the surface temperature and the internal temperature of the essential element with a first loop cycle and determines whether the surface temperature or the internal temperature is higher than a preset temperature. (S3) If the surface temperature or the internal temperature is higher than the preset temperature, performing a PID adjustment to the fan rotation speed according to the surface temperature or the internal temperature of the essential element.
