Antminer Hydro troubleshooting

Failures in the network, component, PSU and the environment can render hydro inoperable. By observing the indicator lights, running status and kernel logs, you can determine why Hydro is not running and the hash rate is low (or 0). This article aims to help you figure out the main fault phenomena and causes of hydro generation, and propose solutions. It can help you troubleshoot independently, improve repair efficiency, take measures to avoid failures and ensure the normal operation of hydro. Here are 4 ways to solve hydro problems:

Ⅰ. Check the ETH port light, fault indicator light, and normal indicator light

First, observe the status of the ETH port light, fault indicator light and preliminarily judge the fault of the hydro.

Fault 1

1. The network cable may not be plugged in properly:

Reconnect the network cable.

2. The network cable may be damaged:

Replace the network cable.

3. The switch is not powered on:

Turn on the switch.

4. The switch is damaged:

Replace the switch.

Fault 2

Hydro is in a high temperature state:

After the miner is powered on, check whether the interface valve is open and whether the water temperature is normal.

Fault 3

Crash unable to obtain IP:

Restart-Reset, if still unable to get the IP, the control board is faulty.

Fault 4

1. Incorrect IP or IP conflict: Change the IP.

2. Network setting error:

If the IP can be obtained, modify it directly in the background. If the IP cannot be obtained, modify it in the background after reset.

3. All the information of the three mining pools is wrong:

Check whether the mining pool configuration is correct.

Ⅱ. Observe the ETH port, indicator lights and Antminer operating status

Determine Hydro failure by observing the ETH port, indicator light, PSU and Antminer status.

Ⅲ. View the Antminer backend user panel interface

The above is to judge Antminer's fault from the outside, and then visually inspect it from the background. Figure 1-1 below shows that the hash rate of hash board 2 is 0, and Figure 1-2 shows that the hashboard 3 is abnormally high temperature.

Figure 1-1  The hash rate of the hash board 2 is zero

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

Ⅳ. View the Antminer background kernel log

If there is no data in the Antminer background or the fault cannot be determined, you need to check the background kernel log. Open the background and click on the kernel log to view detailed operation logs. The following are common log failures and solutions:

Kernel log: records various stages of Antminer operation and can help solve some common problems.

Note*: The following failure symptoms are only for ANTMINER reference only.

Fault 1: Unable to connect to the Internet.

Solution: Check the network cable, replace the network cable, check the switch, and check the network connection status.

Fault 2: Server temperature is too high

Solution: Check whether the interface valve is open and whether the water temperature is normal.

Fault 3: Power supply failure

Solution: Plug and unplug the PSU cable, upgrade the firmware, replace the PSU, check whether the power copper strip screws are tightened, or repair it.

Fault 4: Antminer hash board 4 is missing

Solution: Restart, power off, check if the cable is loose. If it is still abnormal, fix it.

Fault 5: Cannot find hash board

Solution: Restart, power off, check whether the cable is loose, whether the power copper screw is tightened, restore factory settings, upgrade the latest firmware or repair.

Fault 6: Chip test abnormal

Solution: Restart, flash with SD card, if it still doesn’t work properly, repair.

Fault 7: Missing chips

Solution: Restart, flashing with SD card, if still abnormal, repair.

Fault 8: Voltage error, initialization failed

Solution: Restart, plug and unplug the cable, flashing with SD card, and configure the mining pool in the background.
