Case 1: the Miner Cannot Get IP
There are two cases,
1. The new miner cannot get the IP address
Use the method in the following link to return to factory settings after first making sure the DHCP mode of the network has been enabled, routers, and network cables are in working order.
The control board needs to be sent back for repair if it still isn’t working.
2. After changing the network, the miner cannot get the IP address
Changing the IP or going back to factory settings may help you get the new IP if the mine is configured with a static IP; if not, please see 1.
Case 2: the Miner Power Off During the Upgrading Process
Recharge the miner, and if that doesn’t help, try the approach described above.
Case 3: the Hash Board Cannot Be Detected
Replace the miner’s control board with a well-known control board from another miner if it can only detect two or three hashboards. If the problem persists, it means the hashboard(s) is/are damaged; send the control board back for repair.
Case 4: the Miner Cannot Detect the Fan
Replace any bad fans with good ones if the miner can only detect one fan or cannot detect any fans at all. If the problem persists, swap the miner’s control board with another miner to check whether the control board’s fan port has been damaged. If so, send the control board back for repair.
