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.

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

When the power copper busbar is connected to the hash board, the positive and
negative poles of the copper busbar are not connected incorrectly, and the screw
washers of the fixed copper bar must be aligned parallel to the edge of the copper bar,
and the fixed screws must be tightened, otherwise the power board may be burned
out. , control board or power supply, hardware damage caused by copper stripping, is
not covered by the warranty.

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.

The control board must be connected to the fan wiring reliably. If the fan wiring is
disconnected or the connection is poor, the miner may not be able to cool down, the
power board is down-converted, and the power is reduced.
