Abstract

The invention discloses electronic equipment and a method for preventing current from flowing backwards. The electronic equipment comprises a first module, a second module, a first power supply and a second power supply, the first power supply is used for supplying power to the first module; the second power supply is used for supplying power to the second module; and the first module is used for controlling the voltage of the communication path to be a second level signal when the voltage of the communication path between the first module and the second module is determined to be a first level signal after the second module is determined to be powered off. The first module can control the voltage of the communication path to be the second level signal after determining that the second module is powered off, so that the current can be prevented from flowing into the second module and the second power supply from the first module, the risk of current backflow can be reduced, the risk of device damage is further reduced, and the service life of the electronic equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of electronic design, in particular to an electronic device and a method for preventing current backflow. Background technique [0002] With the development of switches, after adopting the X86 system, the modularization process of switches continues to advance. Now high-end switches in data centers usually consist of a central processing unit (CPU) module, a baseboard management controller (BMC) ) module, media access control (Media Access Control, MAC) module, optical module and other modules. The CPU module can realize the control and management of the service card, realize the network protocol control management and data maintenance of each business module; the BMC module can realize the intelligent monitoring of the whole machine, power on and off control, power and temperature status monitoring, etc.; the MAC module can Realize network interaction and forwarding; optical modules can realize photoelectr...
