Malfunction
Boot failure
1、Failure phenomenon
Fan does not turn or LED light does not light up after starting.
2、Possible Cause
Mine fan wiring loose, Miner control board power supply line
disconnected, AC power input is not well connected, power module is
broken, control board is broken, power output short circuit protection.
3、Inspection and repair methods
• Power on the whole miner, turn on the power switch of the miner, and
plug in the network cable connected with the switch (or router).
Check that the network port link light flickers. If the network port
light is not on, it indicates that the MM control board has no power.
It is necessary to check the power line connection, replace the power
supply or check whether there is a short circuit in the power output.
• If the network port light is on, but the LED light of MM control

board is not on, it is necessary to replace the MM control board.
• If the MM control board LED is on but the fan does not rotate, check
the fan connection line or replace the fan.
Can’t mine
1、Faulty phenomenon
• Unable to connect the pool for a long time (more than 5 minutes)
after starting up (the miner lights up yellow for a long time, does
not turn green light, has no hashrate).
• The miner pool can be connected after the machine is turned on (the
LED light of the miner is green), but it has no hashrate.
2、Possible cause
• pool configuration error.
• Network configuration error.
• The miner cannot access the Internet.
• The miner power supply has no main circuit output (wiring error,
overload, short circuit or damage).
• The miner's hashboard does not work。
• overheat protection.
3、Check and repair
• If the PC cannot be connected to the miner through the network, you
can try to restore the factory settings after confirming that the
network environment is normal, the network cable is firmly connected,
and the miner is started normally. The method of restoring factory
settings is shown in Appendix I.
• Check the current firmware version of mining machinery, and it is
recommended to update it to the latest version with FMS. See Appendix
3 for the upgrade method.
• Check the status of the hashboard .
• Click log to view the working status as shown in the figure below. It
should be in work normally. If it is overheating shutdown, check the
fan and ambient temperature as follows.
• Check the number of hash boards shown in the figure below. If the
value is 1 or 2, you need to contact our after-sales personnel for
handling. If it is 0, you need to check the status of the power
supply according to the following.

1. Check the power supply, temperature, network status and fan status,
and click log in the left column, as shown in the figure below:
Check the following fields in the right interface：
2. NETFAIL: The time of disconnection from the pool is recorded (if it
has not been disconnected or has never been connected to the pool,
here is all 0). In this record, the odd number items (items 1, 3, 5)
are the time of disconnection from the pool, and the even number
items (items 2, 4, 6) are the time to restore the connection with
the pool. If only the odd number items have data and the even number
items are 0, it indicates that the connection with the pool is
currently disconnected and has not been restored (usually because
the server at the end of the pool is disconnected due to excessive
pressure, if it occurs frequently for a long time, other mining
pools can be replaced).
• SYSTEMSTATU: The current working status is recorded. It is in work
normally. Among them, hash board: is the number of hash boards in
operation. If it is 1 or 2, you need to contact the after-sales
department for solution.
• TAvg is average chip temperature.
• Vo is average chip voltage range:290mV-350mV。
• PS is PSU status ,include 1-6 item as below：
Item 1: error code. Other values indicate power failure or
output short circuit。
Item 2: voltage supplied to the control board. The normal
value is 12xx.
Item 3: the voltage supplied to the hash board is normally
between 1200 and 1320.

Item 4: the current output from the power supply to the hash
board, which is related to the output power and voltage.
Item 5: the output power of the power supply to the hash
board. The normal value is between 3100 and 3300.
Item 6: the desired output voltage of the power supply to
the hashboard, which is configured by the control board.
If the six parameters in the PS field of the power supply are
all 0, it means that the control board cannot communicate with
the power supply. Please check the circuit connection. If the
connection is correct, the power supply PSU needs to be replaced.
3. Check whether the password configuration of mine pool, miner and
miner is correct.
In the background of the mining machine, click pool on the left
column to check the configuration of pool, worker and password.
Finally, click the Save button to save the settings, restart the
machine, and the configuration takes effect
4. Check network setting
Click Network on the left. The default configuration is DHCP
mode. If all the data here is empty, press F5 to refresh the page.
Note that if you need to use static IP configuration. Incorrect
DNS configuration will cause the miner to lose access to the pool.
The commonly used DNS address in China is 114.114.114.114, and
the commonly used DNS address outside China is 8.8.8.8.
Note: after modifying the configuration, you need to click the
Save button to save the configuration and restart the machine to
take effect.
