Embodiment Construction

[0014] Referring to the accompanying drawings, the content of the present invention will be described with specific examples for its implementation and working process.

[0015] The present invention is as principle structural frame figure 1 As shown, there are many groups of power supplies on the server mainboard to supply power for different devices or different power supplies of the same device. The present invention needs to connect the Power Good signal of the power supply with the logic chip CPLD. The Enable signal of the power supply can also be connected to the logic chip. Not connected, this needs to be completed in the motherboard design stage; from figure 2 As shown in the internal program structure diagram, the logic chip will judge according to the data of the enable control module connected to the power supply Enable signal and the data acquisition module connected to the power supply Power Good, so as to judge whether the power supply is normal, and put...

Abstract

The invention discloses a rapid error positioning method of power supply of server based on complex programmable logic device (CPLD) and belongs to the field of server maintenance. The method includes: connecting a PowerGood signal of the power supply with the logic chip CPLD and an Enable signal of the power supply is capable of being connected with the logic chip; identifying whether the power supply functions properly by the logic chip and the logic chip is capable of identifying results according to data both from an enabling module which is connected with the Enable signal of the power supply and a data collection module which is connected with the PowerGood signal of the power supply; storing the results temporarily in a register, and then transforming the results to a managing chip of the server by an input/output module; transforming the situations of the power by the managing chip through an outward interface which is supported by the managing chip to receiving devices of users. Accordingly, a stage of testing and positioning errors of the power supply can be saved and the errors can be positioned directly.

Description

[0001] technical field [0002] The invention relates to the technical field of server maintenance, in particular to a method for rapidly locating server power failures based on a logic chip CPLD. Background technique [0003] With the continuous development of network technology, the demand for servers is increasing. People pay more and more attention to the maintenance and repair of servers, and a lot of manpower and material resources are invested in the maintenance of servers. The more difficult maintenance of the server is the failure to boot. In the failure to boot, about 80% of the failures are caused by the motherboard not being powered on normally. For this kind of maintenance, professional engineers are required to use professional tools such as oscilloscopes and multimeters. A large number of inspections can locate the problem and repair; this traditional repair method is time-consuming, labor-intensive, and requires professional engineers and professional...
