No Data When Entering the Backend of the Bitmain Antminer L7

No Data When Entering the Backend of the Bitmain Antminer L7

Resolve the issue of no data in Bitmain Antminer L7 backend. Troubleshoot network, temperature, and PIC abnormalities for optimal performance.

Encountering a situation where you can access the backend of your Bitmain Antminer L7 but find no data can be perplexing. In this blog post, we will guide you through the steps to address this issue and restore data visibility. We will explore potential causes such as network malfunctions, high temperatures, and abnormal PIC (temperature sensor circuit). By understanding these reasons and implementing the appropriate solutions, you can resolve the no data problem and ensure optimal performance of your Antminer L7. Let’s dive in and troubleshoot the issue together.

Abnormal Performance

The abnormal performance is characterized by being able to access the backend area of the Bitmain Antminer L7 but encountering a lack of data on the interface, leaving you without crucial information.

Reasons and Solutions

  1. Network Malfunction or Settings Issue: When the Antminer L7 fails to connect to an external network, the interface may not display any data. Check the network cable connection to ensure it is properly connected. Verify that the IP settings and mining pool settings are accurate to establish a stable network connection.
  2. High Temperature: Upon startup, the Antminer L7 may experience high temperatures, triggering automatic protection mechanisms. Look for high-temperature protection notifications in the log. Enhance ventilation, consider adding exhaust fans, install water curtains, and add hot and cold insulation to effectively reduce the room temperature and prevent overheating.
  3. Abnormal PIC: An abnormal PIC can also lead to the no data issue. The log may falsely indicate high temperatures. This problem is often caused by corrosion in the temperature sensor circuit. Analyze the issue and seek assistance to rectify and fix the temperature sensor circuit.


Entering the backend of your Bitmain Antminer L7 and finding no data can be resolved by addressing network malfunctions, high temperatures, and abnormal PIC. By ensuring accurate settings, establishing a stable network connection, managing temperatures effectively, and fixing any issues related to the temperature sensor circuit, you can restore data visibility and maintain optimal performance.
