2. According to the miner contro l board type, upgrade the corresponding firmware version for the miner. The current miner control board types are divided into H3 and H6. Or log in to the IP of the miner in the browser and switch to the overview page, and you can also check the type of control panel.

If the upgrade fails during the upgrade process, please check whether the firmware version is consistent with the miners.

If they are the same, please try 1~2 times again, then the upgrade will be successful;

If they are inconsistent, please restart the miner that failed to upgrade (restart or reboot after power off). Then, after the miner is online, re-select the firmware of the corresponding control board type and upgrade again.
