Troubleshooting the Antminer control board

Phenomenon 1: Miners cannot get IP

There are generally two situations for this phenomenon:

1. The new miner cannot obtain an IP address.

First, confirm that the DHCP mode of the network has been turned on and whether the router and network cable are normal, and then reset the miner to factory settings. If it still does not work, the control board needs to be repaired or replaced with a new one.

2. After changing the network, the miner cannot obtain the IP address.

If the miner has set a static IP, modifying the IP or restoring the factory settings can help obtain a new IP.

Phenomenon 2: Unable to enter the miner backstage

Reason analysis and treatment method:

1. Program error: reset

Antminer reset

2. Browser incompatibility: please change Google or Firefox browser

3. Duplicate MAC address (this phenomenon only occurs on T9+, S9i): You need to update the firmware to fix the duplicate MAC address.

4. The miner changed location:

(1) Set the network of the new mine to the previous configuration;

(2) Restore all miners to factory settings;

5. The control board is damaged: please repair or replace the control board.

Phenomenon 3: Unable to detect the hash board

If the miner can only detect two or three hash boards, please replace the miner's control board with a known control board of other miners. If the same problem still exists, the hash board is damaged, please replace the control board .

Phenomenon 4: No hash rate

Reason analysis and treatment method:

1. Abnormal or wrong writing in the mining pool: correct the address of the mining pool.

2. The fan is damaged: replace the fan.

3. Damage to the hash board: repair the hash board or replace the hash board.

4. The control board is damaged: repair the control board or replace the control board.

5. Network problems: check the network.

Phenomenon 5: The miner cannot detect the fan

If the miner can only detect one fan or the fan is not detected, replace the fan; if it still does not work, replace the miner's control board with another one, and check whether the fan port on the control board is damaged; if you have the same problem, please repair the control board or replace the control board.

Phenomenon 6: The miner crashes during the upgrade process.

If the miner is stuck on the upgrade page, it may be caused by the browser. It is recommended to use Firefox or Google Chrome.

Phenomenon 7: Both the yellow and green lights of the network port are off.

Cause analysis and treatment methods

1. The network cable is not plugged in properly: re-plug the network cable

2. The control board is damaged: replace the control board or repair the control board

3. The other section of the switch is not powered on: power on the switch
