Replacement tutorial for Avalon 1046 1047 control board

Canaan 1046 1047 control board, serving as the "core brain" of Avalonminer, not only execute complex mining algorithms but also manage the overall operation of the miner. Through precise parameter adjustments, it ensures the machine's optimal performance.

In case of a malfunction in the control board, the miner may experience issues such as the inability to find IP or enter the background, missed chains, non-functioning fans, unlit network lights, etc. These not only affect mining efficiency but may also damage other electronic components. Therefore, it is crucial to promptly replace a new spare control board to minimize downtime and reduce losses.

Taking the Avalon 1047 miner as an example, the specific replacement steps for the faulty control board are as follows:

Remove the defective control board:
