Case 1: the Miner Cannot Get IP
There are two cases,
1. The new miner cannot get the IP address
Use the procedure in the following link to restore factory settings after first making sure the DHCP mode of the network has been enabled and that routers and network cables are in working order.
You will need to send the control board back for repair if it still isn’t working.
2. After changing the network, the miner cannot get the IP address
If the mine is configured with a static IP, changing the IP or going back to the factory settings can help you get the new IP; if not, please see 1.

Case 2: the Miner Power Off During the Upgrading Process
If the miner still does not function, try repowering it and then 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 item back to us 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.
Case 5: the Miner Crashed During the Upgrading Process
The browser may be the cause of the miner getting stuck on the upgrading page, so it is advised to use Firefox or Google Chrome.
