Abstract
The invention discloses a mainboard power supply debugging and maintenance method for a multichannel server. The method is characterized in that the time sequence of all power supplies of a mainboard is controlled by CPLD, the CPLD drives a nixie tube to display different numbers to represent different power supply states according to the time sequence requirements and output state of each power supply, and which power supply fails can be learned about by checking the states of the nixie tube. Compared with the prior art, the method has the advantages that the CPLD controls the nixie tube to display set numbers according to time sequence control and the power supply states fed back by power supply chips, the failed power supply chips can be positioned fast, the complex power supply debugging and maintenance of the mainboard of the multichannel server are simplified, and mainboard debugging and maintenance efficiency is increased greatly.

Source is gone wrong, and debugging is taken long enough if checking from the beginning to the end, even professional's debugging is also highly difficult, while also carrying
The difficulty of mainboard maintenance high.
Disclosed Patents file：Entitled " board power supply debugging system and adjustment method ", this document disclose " one
Board power supply adjustment method is planted, more flexible to board power supply control in debugging process, convenient debugging is realized.Its technical scheme
Main points be：A. control terminal detection kernel control module electrifying condition, if detect kernel control module goes up electricity, performs
Step b, otherwise, return to step a；B. control terminal issues initialization information to kernel control module, notifies kernel control module
Debugging starts；C. kernel control module obtains the control command for treating the power supply on debugging board；D. kernel control module parsing
Control command, controls the power supply on board to be debugged to complete set operation；E. control terminal issues operation to kernel control module
The order of completion, terminates this debugging.Additionally, the invention also discloses a kind of board power supply debugging system.Tune in the present invention
Test system low cost, adjustment method is simple to operate, it is adaptable to the debugging of all types of board power supplys ".
Entitled " debugging apparatus of large power supply are exported for multichannel ", this document disclose " a kind of for leading to more
Road exports the debugging apparatus of large power supply, and civil power supplied into DC power supplier by switch module, and DC power supplier
Display module, VRM Voltage Regulator Module and Signal interface module are supplied after civil power is converted into DC voltage.VRM Voltage Regulator Module is adjusted
Section DC power supplier is added in the size of the analog voltage on display module, Signal interface module.Signal interface module with it is upper
Machine and input voltage are connected.Therefore, display module can be after vision-control analog voltage and input voltage.Can realize that power supply is defeated
Enter the real-time monitored of voltage and multiple output channel analog voltages, so as to optimize and improve the efficiency of power supply debugging ".
