1.3 Overheating
The ideal working temperature of the machine is 20 ~ 30 ℃. If the external working temperature
is too high or the fan of the machine is abnormal (refer to Section 2.2), the frequency of the
machine will be reduced due to the overheating of the temperature, which will lead to the hashrate
not reaching the theoretical value.
1.4 High rejection rate
Generally speaking, it is caused by network problems. Firstly, local reasons, poor local network
conditions or poor network wire contact may lead to large network delay, which leads to high
rejection rate; Secondly, external reasons, abnormal mining pool or unreasonable selection of ore
pool will also lead to high rejection rate. For example, the domestic pool server node connected
by foreign customers will cause network delay increase, for some time sensitive machines, the
rejection rate is high, so it is recommended that users choose mine pool servers with close
physical location.
1.5 High hardware rate
Insufficient voltage or abnormal chip will lead to high hardware rate. These problems have been
dealt with in the program, but there are some extreme cases that the software may not be able to
avoid. If the loss of computing power caused by this problem is relatively large, it may be
necessary to contact the after-sales department to return to the factory for maintenance and replace
the defective chip.
2 Other anomalies
2.1 Network abnormality
We can judge whether the network is in normal state by observing whether the network indicator
is flashing normally. If the network is abnormal, the search tool will not find the machine in the
vlan, and the machine itself will restart the main mining program continuously at an interval of
about 30s (the red light goes out and then lights up again). To solve this problem, you need to
check whether the router or network cable is normal, For example, use the network cable to
connect the computer and other devices to confirm whether other devices can access the Internet
normally. If other devices can not access the Internet, check the network. If other devices can
access the Internet normally, there may be something wrong with the miner control board.
2.2 Abnormal hashboard
1）Refer to section 1.2
2）hashboard lacks chips
