Antminer L7 power voltage can not meet the target - L7 Kernel Log

Suppose the power supply voltage is unstable during the operation of the miner. In that case, the hash board of the miner will automatically shut down, resulting in the miner not being able to mine normally. You can troubleshoot through the following points.

Troubleshooting:

1. First, visually check whether the miner's power cable is loose. If it is loose, it is recommended to re-plug it. If the fault still cannot be solved after plugging and unplugging, it is recommended to replace a power cable.

2. It is recommended to replace an Antminer L7 adapter power supply, Antminer APW121417 PSU.

3. Check whether the miner is properly grounded. If it is not grounded correctly, the power supply voltage of the miner may be unstable.
