Problems solved by technology
Using the power-off method, there are only two states of 0V and 12V, and it is impossible to simulate the fluctuation of the input voltage; using DC SOURCE to change the voltage, the maximum rate of voltage switching is 1V / ms, which is a ramp-type voltage change, which cannot be simulated. Instantaneous cliff-like voltage changes, so in many cases the power input problem cannot be reproduced, and the troubleshooting efficiency is low
[0004] It can be seen from this that in the prior art, the troubleshooting method of the power supply is simple, and it is impossible to simulate the instantaneous abnormality of the output voltage of the power supply during the normal operation of the machine, so the failure of the sudden low output voltage of the power supply cannot be reproduced and solved. low efficiency

The present invention provides a DEBUG card circuit and method for simulating the abnormal input voltage of the server. First, the PSU power supply is used to supply power to the main board of the server through the DEBUG card, and the main board works normally. The PSU and DC SOURCE switch the power supply mode, and then instantly change the input voltage of the motherboard. According to the different phenomena and BMC logs displayed by the motherboard for different voltage values and durations, compare them with the original fault symptoms and BMC logs to locate the motherboard. The root cause of the malfunction. The technical scheme of the present invention is easy to operate, and for different abnormal phenomena, the output voltage value is adjusted through the DEBUG card to reproduce the abnormal phenomenon, and the fault location can be made quickly, which greatly improves the problem analysis efficiency, and is applicable to the input voltage of all server motherboards in the market Abnormal troubleshooting, accurate positioning of faults, strong versatility.
Description
technical field [0001] The invention relates to the technical field of servers, in particular to a DEBUG card circuit and method for simulating abnormal server input voltage. Background technique [0002] With the development of network applications, informatization has gradually covered all areas of society. People's daily work and life are more and more communicated through the network, and the requirements for stable server work are also increasing. When the server works abnormally, it is the most important maintenance link for customers to find out the fault as soon as possible, complete the quick repair, and make it return to normal work. In this demand environment, the DEBUG card (voltage abnormality debugging card) that can help locate the problem point as soon as possible came into being. [0003] For the problem of abnormal input voltage, two methods of power failure or DC SOURCE voltage change are usually used to simulate power failure, and then read the BMC log ...
