2.2. Miner Handling and Racking Notes

When in the process of handling and racking the miner, it is strictly forbidden to use the data cable, the power supply control wire or the fan wire as a load-bearing handle of the miner. Lifting the machine and power supply via its cables will result in damage to the connections, loose connections, and physical damage to the control panel. The resulting hardware damage and malfunctions will not be covered by the warranty! 

3. Miner Configuration Environment Preparation

3.1. Miner Configuration Equipment List

3.2. Miner Network Environment

The miner defaults to DHCP to obtain dynamic IP. Therefore, the mine network must be configured with a DHCP server, or the router can enable DHCP to dynamically allocate the IP address service. The running time of the miner, the correctness of the calculation statistics, etc. depend on the network NTP time. The mining machine itself is configured with multiple NTP server addresses of the public network by default. In order to speed up the acquisition of network time and improve the time precision, it is recommended to mine the network. Configure a local NTP server.

4. Miner Connection and Pre-Power Check

（1）Before the wiring and power-on of the machine, according to the warning signs on the side of the machine, shake the machine to check whether there is a radiator or other components loose. This is to ensure that there is no radiator or other components that may fall off before wiring and power-on.

（2）The machine is connected to the power wiring, and the network port is connected to the switch. Check the power control wiring, fan control wiring, adapter board control wiring, and ensure that the fan control wiring is not loose, and the copper line is connected correctly before powering on the machine.

Notes：

（1）When the power copper busbar is connected to the hash board, the positive and negative poles of the copper busbar are connected correctly, and the screw washers ofthe fixed copper bar are aligned parallel to the edge of the copper bar, the fixed screws must be tightened. Otherwise the power board may burn out. For the control board and power supply, hardware damage caused by copper stripping is not covered by the warranty.

（2）The power control wiring between the control board and the power supply must be connected. Otherwise, the power supply voltage output may not be controlled, resulting in low power calculation.

（3）The control board must be connected to the fan wiring securely. If the fan wiring is disconnected or the connection is poor, the miner may not be able to cool down, the power board throttled, and the power reduced.

5. Miner Data Configuration（Configuration on the web page）

5.1. Query the dynamic IP address obtained by the miner

5.1.1. Run WhatsMinerTools software

Miner Data Configuration: Connect PC to the same network the machine is located, run

WhatsMinerTools software on the PC, select the “Detect IP” tab, set the room number,

rack number and layer number of the rack where the mining machine is located, the

location number of the layer, click “Start”.

5.1.2. Check the IP Address Reported by the Miner

（1）After the machine is powered on for about 30s, under normal circumstances, the yellow light of the network port is always on and the green light is blinking. Press the IPFOUND function button (long button highlighted) on the miner control panel for more than 5s, the two LEDs on the right will flash a few times, indicating that the machine has broadcast the IP and MAC address of the unit to the network.

（2）View the dynamically obtained IP, MAC address, and miner position reported by the machine in WhatsMinerTools software.

Notes：

（1）If all the lights on the panel of the machine control panel are not lit after power-on, please check whether the power supply of the 220V power cable and the 16A power cable are reliable and the connection is correct.

（2）If the indicator on the right side of the panel of the machine control panel is on, but the network port is not lit, or the green light is not flashing, check whether the switch is normal, the whether network cable connection is reliable.

（3）The computer and miner running the WhatsMinerTools software must be on the same network segment. Otherwise, the software may not receive the broadcast message from the machine, so the IP Address and MAC Address information reported by the machine IPFOUND button cannot be queried.

（4）If the computer and the miner machine are on the same network segment, and the DHCP service is enabled in the network, after the mining machine IPFOUND button is pressed, and WhatsMinerTools software does not query the IP of the machine, long press the reset button on the machine panel for more than 5s to recover Factory default configuration, then power off the miner machine. Power on to restart, power on for 30s and then press the IPFOUND button to detect the miner IP address.

（5）If the computer is running WhatsMinerTools software, and after clicking “Start”, without manually pressing the IPFOUND button, the software automatically finds the IP Address and MAC address of the machine, the IPFOUND button of the miner may be stuck by the panel. Find the software.

Display the miner corresponding to the MAC address (the MAC address bar code is attached to the miner panel), power off the corresponding miner, and then re-install the control board to ensure that the control panel buttons and indicators are exposed to the mounting holes, and are not stuck.

5.2. Configuration Pool&Worker Data and NTP Server Address

5.2.1. Configuration Pool & Worker

（1）After logging in, go to the Configuration – CGMiner Configuration page.

（2）In the Configuration – CGMiner Configuration page,modify the mine pool address, mine worker name, and after modifying click “Save & Apply” in the lower right corner to save the modified configuration.

After the configuration of the mining pool is modified, the modified configuration must be restarted after the CGMiner program is restarted or the control panel is restarted.

（3）Restart CGMiner to check whether the configuration modification takes effect. In the miner interface, select: Status – “CGMinerStatus” to enter the CGMiner running status interface.

（4）Restart the control board and check whether the configuration modification takes effect. (If you do not choose to restart CGMiner, after the configuration is modified and saved, you can also restart the control board to make the configuration take effect.)

In the System interface, click ”Reboot”.

After restarting for about 30s, the machine system will automatically jump to the login interface.

5.2.2. Modify the NTP Synchronization Server Address (optional)

（1）After logging in, select System – System Configuration in the interface to enter the CGMiner configuration page.

（2）In the CGMiner configuration interface, add or modify the NTP server address. The miner has been configured with four NTP server addresses by default. You can modify or add the NTP server address to the local NTP server address according to the mine situation.

（3）After modifying the NTP server address, click “Save & Apply” in the lower right corner.

5.3. Configuration the Static IP Address (optional)

Modify the IP address obtained by the mining machine DHCP to the static IP address of the mine operation network planning.

（1）Enter the machine dynamic IP in the browser and log in to the mine interface with the admin user and the default password admin.

（2）After logging in to the machine, in the miner interface, select: Configuration->Interfaces to enter the network interface configuration interface.

（3）In the “Configuration” interface, click “Edit”.

（4）In the interface modification page, select “Static address” for the protocol and click “Switch protocol”.

（5）In the static address configuration interface, change the IP address, mask, gateway, broadcast address, and DNS address to the actual planned address of the mine. After editing, click “Save & Apply” in the lower right corner.

After saving the application, you need to re-use the newly set static IP address to log in to the mining machine (otherwise the page will display as loading until the loading fails).

6. Miner Operation Status Check

After the mine is connected to the operation network, log in to the machine and check the running status of the machine.

（1）In the miner interface, select: Status->CGMiner Status to enter the CGMiner running status interface.

（2）View the overall calculation of the mining machine, front and rear fan speed, connection to the mining pool, single board computing power, board temperature and other operating conditions.

Notes:

（1）The mining machine is connected correctly. When the network is normal, the mining machine will automatically perform the frequency search test after power-on. The search frequency test phase takes about 15 minutes. After the search frequency is over, it will enter the formal mining stage. It is the computing power of normal operation. If the search frequency is not over yet, the mining power will be lower than the normal operation.

（2）If the temperature of the air outlet of the power board is higher than 85 degrees and the fan speed is above 6100 rpm, the mining machine will run at a reduced frequency, and the power will be lower than the normal operation. It is necessary to do a good job of ventilation and

cooling measures in the operating environment of the mining machine to ensure that the ambient temperature of the mining machine is below 40.

（3）If the fan wiring is not reliably connected to the control board, the corresponding fan speed in the miner interface is 0, which leads to the mining machine overheating. When the temperature is too high, the power board is reduced, and the computing power is reduced.

（4）If the power board temperature is not detected in the status interface, the miner machine needs to be powered off, and the power cable and data cable of the corresponding power board re-plugged and connected (one end of the control board and one end of the hash board) to ensure a reliable connection.
