How to quickly replace the Antminer T21 APW11A1216-1a power supply?

The APW11A1216-1a PSU is specifically designed for Antminer T21 air-cooled miners. With an input voltage of 380V to 415V AC and an output voltage of 12V to 16V DC, it provides reliable power assurance for the stable operation of miners. Moreover, the APW11A1216-1a PSU is equipped with three cooling fans that effectively address issues like overheating inside the power supply unit, ensuring long-term stable operation.

When a power supply malfunctions, it may manifest as the miner failing to start, unstable power output, non-functioning fans, abnormal noise, or non-illuminated indicator lights. To ensure the normal operation of the T21 miner, it is recommended to immediately stop using it and replace it with a new power supply once any of the above issues arise.

Here are the detailed steps for quick replacement:

1. Disassemble the faulty power supply unit:

After disconnecting the miner's powering, remove the protective cover plate above the power supply. Unscrew the fixing screws of the conductive copper piece and unplug all connecting cables. Push it out and take it off towards the miner air outlet.

2. Install the new APW11A1216-1a power supply:

Inspect the appearance and components of the new PSU to ensure they are in good condition. Align it with the sliding rail on the side of the miner and carefully push it towards the miner's air inlet to install it in its original position.

3. Assemble the miner:

Install the conductive copper sheets and tighten the fixing screws. Connect the relevant cables.

Reinstall the protective cover plate and secure it with screws.

4. Test operation:

Power on the miner and observe its operating status.

Continuously monitor the miner's operation to ensure stable powering.

In the miner's operation, the power supply is one of the crucial components ensuring its stability and reliability. By quickly replacing the faulty APW11A1216-1a PSU, we can effectively ensure the normal operation of Antminer T21 and minimize the downtime losses caused by power failure. Therefore, timely maintenance and replacement of power supplies are crucial for the continuous operation of mining farms.
