It defaults to DHCP
to obtain a
dynamic IP address
when the miner
leaves the factory.
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 of
the 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".

12 / 30
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.

13 / 30
（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

14 / 30
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.

15 / 30
In the CGMiner Status interface, click "Restart CGMiner" to restart the CGMiner
process.
（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”.

16 / 30
In the Restart interface, click "Perform reboot" to confirm the restart.
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.

17 / 30
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".

18 / 30
（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,

19 / 30
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.
