One of the Hash Boards malfunctioned, what to do?
- Send us the logs so the MARA Team can check for SW fault. The ASIC can be safely run as is - MARAFW will ignore the faulty hash board and keep mining using the rest of the hash boards. Replacing the faulty hash board with a spare one with the same properties (same model, same hash rate) is also possible.
- It is not recommended to remove the hash board and leave the space empty as the airflow will drastically change which increases the risk of damaging the other hash boards.
The miner shut down, what happened?
A complete miner shut down most probably points to a HW fault. Follow the troubleshooting guide to self-analyze the issue or contact our MARA Team.
The miner is not mining
The miner can stop mining, for example, if the temperature is too high (reduce the performance settings), or there is a HW fault. Check the logs and follow the troubleshooting steps described here.
All pools are dead
- Make sure that the pool URL and credentials are correct
- Check the network settings and make sure that the required ports are open (typically 3333)
- Apply a custom DNS in case DNS-level blocking is in place (for examples 8.8.8.8 and 1.1.1.1 allow such connections)
I can see errors in the log, what do they mean?
Check out our self-troubleshooting guide or contact our support.
The miner cannot be accessed using SSH
The SSH connection was closed due to security reasons. The provided API should be sufficient under normal circumstances. In case there is a missing option, please let us know by filling a ticket here.
The Hash Board is not hashing or the Hash Rate is very low
There might be several reasons for a low hash rate, from a simple SW fault to a dying Hash Board:
- Reboot the device to solve sporadic SW glitches
- Unplug the device for a couple of minutes (to completely discharge the capacitors) and then re-plug it
- Check the cables and ensure they are firmly connected. Check the screws on the PSU and the Hash Boards
- Unplug the device and clean it to solve an issue with dust short-circuiting the components
- Try another PSU
- If none of the above methods helped, the Hash Board might be dead and has to by professionaly repaired
- The faulty Hash Board can be replaced with a spare one with the same specification
- It is NOT recommended removing the Hash Board without replacing it with another unit as the empty space affects the air flow and the cooling.
