Cause analysis and treatment methods:

1. Press IP to reset and upgrade the firmware;

2. The damage to the hash board is damaged: send the whole miner to the nearest repair center or replace the hash board.

Phenomenon 14: The temperature shows a negative number

Cause analysis and treatment methods:
