Problems solved by technology

The occurrence of burn-in is generally a short circuit at the input or output of the power supply, which leads to the generation of large current and burns the components. In severe cases, there will be an open flame
[0004] The four-way server computing board does not need hot-swapping function, so there is no need for a soft-start switch at the input end. In the event of a short-circuit at some specific input end or load end, there is no protection circuit on the computing board, and it is easy to burn components or even open flame phenomenon

Abstract

The invention relates to an overcurrent protection device for a four-way server. The overcurrent protection device is characterized by comprising a Pmbus address unit arranged on a PSU power module, the Pmbus address unit is connected with a detection unit through an I2C bus, a current comparator is arranged inside the detection unit which is connected with a control unit, and the control unit controls the PUS power module to be switched on or off.

Description

technical field [0001] The invention belongs to the technical field of servers, and relates to an overcurrent protection device and method for a four-way server. Background technique [0002] A server, also called a server, is a device that provides computing services. Since the server needs to respond to and process service requests, generally speaking, the server should have the ability to undertake and guarantee services. At present, servers are divided into non-X86 servers and X86 servers according to the architecture, and divided into entry-level, work-level, department-level, and enterprise-level according to application levels; according to the number of CPUs, they can be divided into low-end two-way, mid-range four-way, high-end eight-way, etc. , Widely used in government, banking, finance, railways, small and medium-sized enterprises, etc.; among them, the share of four-way servers is particularly prominent in the server market. [0003] With the rapid development ...
