Understanding Your Miner’s Signal Lights: A Comprehensive Guide

The status of your ANTMINER can be easily determined by observing the signal lights on the miner. There are several lights on the miner, and their meanings are as follows:

• Yellow light at the ETH port (A)
• Green light at the ETH port (B)
• Fault light (red) (C)
• Normal light (green) (D)

The lights’ status may change during the server startup process. Here’s a rundown, using the ANTMINER 17 series as an example:

1. When the machine is powered on, both the fault and normal lights illuminate simultaneously. This means that the machine is starting to initialize.
2. Once initialization is complete, the fault light flashes while the normal light goes out. The machine then starts to connect to the mining pool.
3. After successfully connecting to the mining pool, the fault light goes out, the normal light starts to flash, and the hashrate is reported.

Find a Specific Miner by Indicator Lights (15/17 series)

1. Log in to the miner’s user interface and click System → Locate.
2. Click “Start Blink”. Both the fault and normal lights on the server will flash simultaneously for 300 seconds.
3. After 300 seconds or once you click the “Stop Blink” button, both the fault and normal lights will resume normal operation.

19 Series Server Search Instructions

1. Log in to the miner’s user interface.
2. Open the “Locate Miner” function in the upper left corner (it will be green). Both the fault and normal lights will start to flash.
3. Once you close the “Locate Miner” function (it will be grey), the miner positioning will stop.

Indicator Light Interpretation During Server Operation

Fault Light (Red)	Normal Light (Green)	Working Conditions
Extinguish	Flashing	Normal
Flashing	Extinguish	Fault 1
Long Light	Extinguish	Fault 2
Extinguish	Long Light	Fault 3
Extinguish	Flashing	Fault 4
Flashing	Flashing	Fault 5

Faults:

• Fault 1: The server might have one of the following issues:
  1. Check for high or low temperature protection.
  2. Verify that the network is normal.
  3. Confirm the fan is functioning properly.
• Fault 2:
  1. Check if the mining pool configuration is correct.
  2. Try upgrading the firmware.
• Fault 3:
  1. The network connection might be abnormal. Check for high latency.
  2. There could be an IP address error or conflict.
• Fault 4: The control board may be faulty. Use an SD card to upgrade the control board or replace it.
• Fault 5: The hashrate value might be lower than 90% of the normal value. Check for high network latency.

ETH Port Light

• Normal status: The yellow light is steady while the green light is flashing.
• Fault status: Both the yellow and green lights are off. This can be due to:
  1. The network cable might not be plugged in properly. Try re-plugging it.
  2. The control board may be damaged. Consider repairing or replacing it.
  3. The switch at the other end may not be powered on. Ensure that the switch is powered on.

Understanding these light signals will help you keep your miner in the best condition and quickly diagnose any potential issues.
