Hydro Miner Troubleshooting: Identifying & Resolving Issues

This guide provides comprehensive troubleshooting steps to resolve common issues with the Hydro Antminer. There are four methods to troubleshoot the device:

1. Check the ETH port light, fault indicator light, and Normal indicator light.
2. Observe the ETH port, indicator light, and the running status of the Antminer.
3. View the ANTMINER’s backend user panel interface.
4. View the background Kernel Log of the ANTMINER.

Checking the ETH port light, fault indicator light, and Normal indicator light

Observing the status of the ETH port light, fault indicator light, and Normal indicator light can help preliminarily judge the fault of the Hydro Antminer. Below are the possible faults and solutions based on different light conditions.

• Fault 1: Check network cable and switch conditions. Solutions may include re-plugging the network cable, replacing damaged network cables or switches, and ensuring the switch is powered on.
• Fault 2: Hydro is at high temperature. Make sure the interface valve is open and the water temperature is normal.
• Fault 3: Crash and inability to obtain IP. Try Restart-Reset, if still unable to obtain IP, the control board is faulty.
• Fault 4: IP conflicts or incorrect network settings. Change IP, adjust network settings, or check mining pool configuration.

Observing the ETH port, indicator light, and Antminer’s operation status

By observing these aspects, you can identify several failure causes and solutions, such as control board faults, unstable PSU or voltage, loose power cords, and cold PSU conditions. Damages to the PSU or control board might require replacements. In case of low hashrate, check hashboard conditions, power consumption, and cables.

Viewing the ANTMINER’s backend user panel interface

You can visually inspect the miner from the backend user panel interface. This can help identify issues like zero hashrate on hash boards or abnormally high temperatures. Please refer to the figures below for visual references.

Figure 1-1: The hashrate of the hash board 2 is zero

Figure 1-2: The hash board 3 is abnormally high temperature

Viewing the background Kernel Log of the ANTMINER

If you still can’t determine the cause of the issue, check the background Kernel Log, which keeps a record of the Antminer’s operation stages. This log can help identify common issues like internet connectivity problems, high server temperatures, PSU failures, missing hash boards, and chip test abnormalities. Based on the fault identified, solutions may include checking network connections, cooling the server, replacing the PSU, restarting the device, checking cables and screws, and updating firmware.

Remember, these are just common troubleshooting steps. If you can’t fix the issue using these steps, please contact the product’s customer service for further assistance.
