Impact of Power Outage and Network Disconnection on Running Miners

Start with safety and logs

Power down before opening a miner, label cables before moving boards, and capture logs before repeated reboots erase useful evidence. Record model, firmware, pool, uptime, fan speed, temperature, reject rate, chain count, and the exact error text.

Confirm the fault class

Separate configuration faults from hardware faults first. Pool errors, DNS failures, bad worker names, overheating, weak power, fan faults, and missing hashboards can look similar from the dashboard but require different fixes.

Document the test path

Change one variable at a time and keep the before/after result. Note cable swaps, PSU swaps, firmware changes, pool changes, fan replacements, ambient temperature, and whether the fault follows a hashboard, control board, network, or power source.

When to escalate

Escalate to professional repair when there is a burned smell, melted connector, breaker trip, corrosion, repeated hashboard loss, liquid exposure, or a board-level fault that returns after a basic cable, power, firmware, and airflow check.

After the fix

Run the miner long enough to confirm stable accepted hashrate, fan behavior, chip temperature, reject rate, and pool-side reporting. A dashboard that looks normal for five minutes is not enough evidence for a recurring power, heat, or hashboard fault.

Power Outage

Miners are designed for long-term operation; there is no power switch or shutdown button. However, if you must turn off the miner, keep the following points in mind:

  1. Avoid powering off the miner in high humidity environments. The miner generates substantial heat and, when turned off, the temperature drop can cause condensation and moisture, leading to circuit corrosion over time.
  2. Do not turn off the main circuit breaker directly; power off the miners one by one in an orderly manner. Batch power outages can cause voltage surges, potentially damaging the miner due to the high power requirements.

Network Disconnection

When the miner loses its network connection, it will automatically attempt to reconnect. After multiple reconnection attempts, the miner may shut down for protection. Similar to the power outage scenario, the miner’s temperature changes significantly when powered down, increasing the risk of corrosion due to condensation in high-humidity environments.

If the miner is disconnected from the network, it cannot mine effectively but continues to consume electricity. When the expected disconnection time exceeds 15 minutes, cut off the power directly. When cutting off the network, always cut off the power supply first.

In summary, both power outages and network disconnections can impact running miners, potentially causing temperature fluctuations, corrosion, and equipment damage. Minimize these risks by taking appropriate precautions and adhering to proper powering-off and network disconnection procedures.
