The hydro cooling mining rigs adopts a standard 2u structure design and is installed on a standard 19-
inch hydro cooling cabinet. The front and back of the cabinet after the installation of the miner, respectively.
3.2 Steps for putting the miner on the shelf:
（1）The first step is to slowly push the mining miner into the cabinet along the card slot. Note that
two people are required to operate. Here is an example of a full cabinet on 20 mining miner.

（2）The second step is to loosen the screws on the transportation fixing button on the rear panel of
the miner, rotate the transportation fixing button and hook it with the cabinet hook, then tighten the screws,
hook the water inlet side and then the water outlet side. The fixing example. Note: When the cabinet is
transported with the miner, the miner must be hooked to the cabinet and tightened;
（3）The third step is to fix the front panel of the mining miner with the cabinet by screws (the cabinet
has floating nuts). An example of screw fixing. Note: When the cabinet is transported with the mining miner,
the front panel screws must be tightened and fixed;
（4）The fourth step is to plug in the water inlet and outlet pipes of the mining miner, that is, first
remove the protective caps of the joints, and then connect the female quick connector on the inlet and
outlet water pipes with the male quick connector on the mining miner. Pay attention to the plugging
position. The left side of the figure shows after the plugging is completed, the right side of the figure shows
two situations of plugging in place and plugging not in place;

（5）The fifth step is to connect the network cable and power cable. The power cable adopts the
original factory configuration power cable. An example of the connection of the network cable and power
Steps for unloading: first shut down the miner, and then operate in reverse according to the put-on
steps.
3.3 Attention:
（1）The female quick connector and power cord must use the original accessories.
（2）The quick connector is plugged and unplugged as shown in the figure. After normal plugging, the
male and female heads are connected, the liquid can flow, and the quick connector will be self-locking. After
unplugging, the male and female heads will be blocked in both directions and will not leak. After the
insertion is completed, check whether there is a virtual insertion of the quick connector by pulling the hose
at the head of the pagoda;
Insertion indication: Hold the pagoda head end of the quick connector (female head) and push it
forward, and not hold the movable ring.Insertion indication: Hold the pagoda head end of the quick
connector (female head)and push it forward, and not hold the movable ring.

（4）Before powering on the miner, confirm that the cooling system is circulating
normally (the air in the pipeline has been emptied).
（5）When all the miner of the same heat dissipation system are turned on at the same
time, in order to avoid the overheating protection of the mining miner due to the out-
of-control water temperature control of the heat dissipation system, it is recommended
that the heat dissipation capacity of the heat dissipation system be fully turned on
before all the miner are turned on (that is, the temperature control components of the
system are fully loaded. , Such as fans, circulating pumps, electric valves, etc. fully
open), after the power of the miner rises close to the rated power, the heat dissipation
system enters the state of automatic water temperature control and adjustment.
（6）Under normal circumstances, there is no cooling water in the hydro cooling plate of
the miner. When the miner is connected to the heat dissipation system, air will enter
the pipeline system and cause the system to lack water. Therefore, the pipeline system
needs to have an exhaust device and an automatic liquid supplement device. When the
system is running, it is not possible to connect multiple miner that do not contain
cooling water at the same time in a short period of time, because at this time the
system will suddenly lack a large amount of water, the water supply is not timely, and
the air is mixed into the circulation system, which will easily cause the water pump to
run with gas and be damaged. And it may cause the local chips of other miner to overheat,
burn out the mining miner or affect the hashrate. It is recommended to circulate water
to empty the air in the hydro cooling plate of the miner before it is put on the shelf.

2、Provide NTP network time
for miner
It defaults to DHCP to
obtain a dynamic IP
address,when the miner
leaves the factory.
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 miner 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.

6.Data Configuration（Configuration on the web page）
6.1 Query the dynamic IP address obtained by the miner
Miner Data Configuration: Connect PC to the same network the miner is located, run
WhatsMinerTools software on the PC, select the “IP Monitor” tab, set the room number, rack
number and layer number of the rack where the mining miner is located, the location number of
the layer, click "Start".
After the miner 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 miner has broadcast the
IP and MAC address of the unit to the network.
View the dynamically obtained IP, MAC address, and miner position reported by the miner in
WhatsMinerTools software.

Notes：
（1）If all the lights on the panel of the control board 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 control board 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 miner, so the IP Address and MAC Address information reported by the miner
IPFOUND button cannot be queried.
（4）If the computer and the miner miner are on the same network segment, and the DHCP
service is enabled in the network, after the mining miner IPFOUND button is pressed, and
WhatsMinerTools software does not query the IP of the miner, long press the reset button
on the miner panel for more than 5s to recover Factory default configuration, then power
off the miner miner. 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 miner, 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.
