S50, writing the corresponding firmware file into the bottom hardware with abnormal operation through the expander, and restarting the large system after the writing is completed so as to complete the repair of the bottom hardware with abnormal operation.
The expander runs between the large system and the underlying hardware (such as CPLD, FPGA, PSU, etc.), belongs to the information collection and transfer station, but does not have a file system, so that a block of area is divided in a nonvolatile storage device (such as FLASH or NVRAM) storing the expander for storing firmware files of the underlying hardware, so that when the large system is unloaded and the underlying hardware runs abnormally, the expander can directly write the corresponding firmware files into the underlying hardware by reading the corresponding firmware files in the FLASH to repair the underlying hardware, and the normal running of the whole server is restored.
Wherein large system refers to an adaptation on LUNIX systems on the server CPU for presenting the information of the server to the client.

2) Testing and production stages: in the test and production debugging stage, a large system does not exist, and because test and production line staff are not product research staff, the level is uneven, the debugging means are various, a plurality of abnormal scenes with extremely small probability and extremely difficult positioning can be triggered, if the situation that the firmware cannot be started normally occurs, the means are limited, the problem is usually solved by replacing a chip, the efficiency is low, and the abnormal firmware is directly updated and repaired by an expander, so that the test and production efficiency can be improved;
3) Customer site stage: the product sent to the customer site is often not the final firmware version, the large system may not be adapted, if the bottom firmware is started abnormally, because the product is the customer site, a rough method of directly replacing a chip or firmware FLASH cannot be adopted, and the abnormal firmware is directly updated and repaired by an expander, so that the perception of the customer on the abnormality is reduced, the customer experience is greatly improved, and the public praise benefit is brought to the company.
