What is the replacement method for the Antminer 4P voltage regulator cable?

The Antminer 4-pin voltage regulation cable is an efficient data transmission cable specifically designed for Antminer series miners. Its high-quality material ensures the efficiency and stability of data transmission between the miner PSU (such as APW9, APW9+, APW12) and the control board.

This voltage stabilizer wire is suitable for most Antminer miners, including the S19 series, T19 series, E9, D7, L7, S17 series, T17 series, etc. In addition, it's available in two specifications: 18cm and 60cm, which can flexibly adapt to the needs of different mining machines and application environments.

When the miner's voltage regulator wire is damaged, the data transmission between the control board and PSU will be cut off, causing failure to correctly execute the instructions of the control board, which seriously affects its stable operation. Furthermore, the damaged voltage regulator cable can also lead to voltage fluctuations, affecting the safety and stability of the miner's internal electronic components. To avoid further losses, please replace a new 4P voltage regulator cable immediately to help the miner restore its optimal working condition.

Taking the Antminer L7 miner as an example, the specific replacement steps for the 4P voltage regulator wire are as follows:

1. Shut down the miner, disconnect its power cord from the power outlet, remove the protective cover plate above the PSU first, then press the shell release button above the control board (as shown in the figure below), and gently lift it to expose the internal components.

2. Find the location of the faulty voltage regulator wire, next gently unplug its plugs from the control board and the power supply.

3. Check the appearance of the new Antminer 4P voltage regulator wire to ensure that the pins are intact, the cables are not damaged, and the markings are clear. Then connect it (insert the end with the 1*4P plug into the interface of the PSU, and the other end with the 2*2P plug connects to the control board), ensuring that the pins are aligned with the interface and the connection is secure.

4. Install the two protective cover plates removed earlier back to their original positions, next, tighten them with fixing screws.

5. Turn on the miner to observe its operating status through its backend interface.

The voltage regulation wire is like the "blood vessels" of the miner, ensuring its smooth operation. Timely replacement of faulty components can ensure that the machine is always in its optimal operating condition, bringing more profits to our mining business.
