Once you connect the power cable, you need to connect the Ethernet cable next. First, you need to connect it to the Ethernet port on the Yibit E9.2 Bitcoin miner machine, located on the front side. Then, the other end of the Ethernet cable needs to be connected to the router. Once you feed the power, the miner will automatically assign the default IP address. This default IP address will be 192.168.80.140. So, you need to make the necessary adjustment in your LAN settings to get the access. First, you need to configure it to 80. You can also make use of the official management software to make the necessary modifications to the IP address of the Yibit E9.2 Bitcoin miner machine.

 

You can download the official software from the below link.

When you try to download it, it will ask for a password. The password is qejh.

 

Here, the network segment is 0. You need to make the necessary modification in the IP address of the Yibit E9.2 Bitcoin miner machine using the management software. Once the IP address is set, you can enter it in the network browser to enter the background. You need to follow the steps mentioned below to see the background details of the Yibit E9.2 Bitcoin miner machine.

 

First, you will have to enter the username and password for the miner machine. If you are using a new machine, the username and password will be admin by default. Once you log in, you can change the username and password.

 

Now, you need to set up the mining pool. You need to enter the miner’s name and the miner’s IP address. You must also enter the details for the backup mining pool. Once you complete these settings, you can click on the Save option. Now, the Yibit E9.2 Bitcoin miner machine will restart automatically, and new settings will be loaded into it.

Testing of Yibit E9.2 Bitcoin miner machine

We will perform various tests on the Yibit E9.2 Bitcoin miner machine.

Before starting the tests, we will measure the indoor ambient noise. The measured ambient noise level is around 39 dBa. We will also measure the ambient temperature. The measured ambient temperature is around 32 degrees Celsius during the daytime, and the temperature dips to 30 degrees Celsius during the night.

The Yibit E9.2 Bitcoin miner machine will be operating at default frequency. This frequency value is 835. The computing power of the Yibit E9.2 Bitcoin miner machine at this frequency is 12.04 T.

The total power consumed by the miner machine is around 1515 W when the computing power is 12.04 T.

Yibit E9 2 2

Once the Yibit E9.2 Bitcoin miner machine normally runs for a certain period of time, you can observe a frequency jump. The miner will switch the frequency of operation from 850 to 860. This switch in frequency will happen according to the ambient temperature and the operating status of the miner machine. The Yibit E9.2 Bitcoin miner machine is made to run for a long time. The average computing power of the miner machine during this long run is around 12.58 T. The computing power curve of the Yibit E9.2 Bitcoin miner machine is found to be stable. There are no major fluctuations in the computing power curve.

Yibit E9 2 25

The measured value of power during this time is 1566 W.

Yibit E9 2 1

Now, we will go ahead with the noise measurements. We will measure the noise from the miner when the mining machine is running in the normal condition. The speed of rotation of the fan is around 5900 rpm during this time. This measurement is taken at a distance of 20 cm from the Yibit E9.2 Bitcoin miner machine.

Yibit E9 2 28

Now, we will measure the temperature at different parts of the Yibit E9.2 Bitcoin miner machine. All the temperature measurements are captured when the miner machine is running in normal conditions. The Yibit E9.2 Bitcoin miner machine is running stably during this time. The measured value of temperature on the hash board is around 60 to 75 degrees Celsius.

Yibit E9 2 26

We will measure the temperature at the air inlet side of the miner machine. The air intake happens through this side of the miner. So, the temperature will be low on this side. This temperature is around 34 degrees Celsius.

Yibit E9 2 27

We will measure the temperature at the air outlet side of the miner machine. The hot air gets pushed out from this side of the miner machine. So, the temperature is going to be higher on this side. This temperature is around 43 degrees Celsius.
