Antminer S19XP hash board repair course

As the release time of Bitmain Antminer S19XP goes by, long-term operation makes the powerful machine begin to malfunction, antminer S19XP is not hashing or stops hashing. In order to help friends in the cryptocurrency circle achieve independent maintenance and reduce downtime, ZMRC has made precise preparations and now officially launches S19xp maintenance traning. In the learning course, we will explain the structure, powering, signals and common faults of the hash board, so that you can successfully master how to quickly and effectively troubleshoot, diagnose and repair abnormalities, and then you can easily manage the operation of the mining machine, save maintenance time and costs.

When the Antminer S19XP miner operating interface is abnormal and displays a low hash rate or 0 hash rate, we should enter the Kernel Log to view the specific fault.

ZMRC summarizes common failures that will show up in the kernel log:

Fault 1: "Chain 0 only find X asic, will power off hash board 0"

Notice: The number "X" can be any number, that is, the number of detected ASIC chips is less than the designed number.
