What Do Antminer E9 Miner’s Signal Lights Mean?


If you’re new to mining and have recently acquired Bitmain Antminer E9, understanding the signal lights can be confusing. But don’t worry, we’ve got you covered. In this post, we’ll explain what the different signal lights mean and how to troubleshoot any issues that may arise. So, let’s dive in!

What do Antminer L3 Miners' signal lights mean?

A. Yellow light at the ETH port

B. Green light at the ETH port

C. Fault light(red)

D. Normal light(green)

The Status of the Indicator Light Changes During the Server Startup

1. When the Bitmain E9 is powered on, the fault and running indicators will light up at the same time, and the machine will start to initialize.

2. After the initialization is complete, the fault indicator flashes, the operation indicator goes out, and the machine starts to connect to the mining pool.

3. After successfully connecting to the mining pool, the fault indicator will go out, the running indicator will flash, and the hashrate will appear.

Find Server by Indicator Light

1.Log into the background interface, click System→Locate,

2. click “Star Blink”, the server fault light and normal light will flash for 300 seconds at the same time,

Fault 1:

Go to the background to check the log and confirm whether the server has the following faults.

1. Whether the server is high temperature or low-temperature protection

2. Check if the network is normal

3. Check if the fan is normal

Fault 2:

1.Check if the mine pool configuration is correct

2.Upgrade firmware

Fault 3:

1.The network connection is not normal, check the network status for high latency

2.IP is incorrect or IP conflict

Fault 4:

The control board is faulty, use the SD card to upgrade the control board or replace the control board

Fault 5:

The hashrate value is lower than 90% of the normal value,check if the network latency is high,

ETH Port Light Status and Reasons

1.Normal status: yellow light long light,green light flashing

2.Fault status:the yellow and green lights are not on

Reasons for fault status:

①The network cable may not be plugged in properly, you need to re-plug the network cable;

②The control board may be damaged and needs to be repaired or replaced;

③The switch at the other end is not powered on, and the switch needs to be powered on.
