Precautions for Use:

  1. Before using the PSU, please ensure that your local voltage and power outlets are compatible with the requirements of the product. Output voltage from the power socket should meet the product’s voltage requirement. The leading‐out terminal model, polarity and quantity must also be in accordance with the product requirements stipulated in this guide.
  2. Please ensure that the PSU appears to be in good shape and has not suffered any damage in transit. If the exterior of the PSU appears damaged, do not use it.
  3. Make sure that the ground electrode of PSU is properly grounded to ensure the electricity safety and EMI reduction.
  4. As different countries have different power outputs, we do not supply an AC input cable with our PSUs. Customers should purchase an AC input cable output that is compatible with the local power grid plug. The type number of the cable end interface to be connected with the power panel is C13, and the sectional area of copper conductor for cables should not be less than 1 square millimeter.
  5. The PSU must be installed in an dust‐free environment with good and unobstructed air circulation. Any items blocking the air flow of the PSU is prohibited and under no circumstances should the PSU be installed in an enclosed place. Installation also should not be done in environment where there is high condensation or high level of salt content and humidity in the air.
  6. The correct way to use the PSU is to connect the output wire terminal, and then connect the input cable after the load and PSU output terminals are connected. Either connecting or disconnecting the output terminals are forbidden when the PSU is powered on. Voltaic arcs generated by excessive DC can damage DC output terminals and pose a fire hazard.
  7. Maintaining a good working environment and derating can greatly prolong the lifespan of PSU. It is generally recommended that the load power not exceed 90% of the rated power of the PSU and the temperature not exceed 50 degrees Celsius. It should be used in a dust‐free, non‐polluted area where there is low humidity and low salt content in the air. The derating method will also allow the PSU to work at a higher efficiency point, which can help in electricity savings.

Thirteen PCI‐e connectors are located at the top of the Antminer S9 Hydro server for connecting the PSU as follows:

  • Twelve PCI‐e connectors for the hash boards. Each hash board has three PCI‐e connectors.
  • One PCI‐e connector located on the controller.

Note:  Each hashboard must be powered by the same PSU to prevent possible damage and instability.

To connect the power supply: 

1. Connect PSU power cable connectors to each of the nine PCI-e connectors on the top of the Antminer S9 Hydro server, ensuring that each hash board is powered by the same PSU.

4. Connect a PSU power cable connector to the Antminer S9 Hydro PCI-e connector on the controller.

5. Connect the network cable to the ETH port.

6. To power up your Antminer S9 Hydro server, connect the PSUs to the power wall outlet.

Note: If you are using more than one PSU, power up the PSU connected to the controller AFTER you have Powered up the other PSU(s).

3.Connecting Antminer S9 Hydro Hex to Server

S9 Hydro

A、Fan connection

Four 4‐pin connectors of the control board and two connectors separated by one line will be connected with 6 fans. The plug must be inserted in place, the fan line order does not matter as long as it is connected.

B、Pump connection

The control board has a black 4‐pin connector to which the pump must be connected.

C、Connection of pipelines

The Antminer S9 Hydro pump should be connected in series with the pipe, and the joint should be clamped with a buckle. The figure below shows the recommended connection.

Attention: The position of pipes may be slightly adjusted and it won’t have any effect on usage.

For better heat dissipation effect, it is recommended to connect pipes in this way.

S9 Hydro

Precautions for Use:

1.When connecting the fan and pump connectors on Antminer S9 Hydro Hex, please pay attention to the position of the corresponding connector on the control board. As the power of pump varies from fan’s, the flow through capacity of the connector on the control board also varies. The wrong insertion may cause damage to the control board.

2.The water replenishment period of Antminer S9 Hydro Hex is about 2‐ 3 months. Please pay attention to checking the liquid level of the water tank regularly for replenishment so as to avoid the low water level which can affect the heat dissipation efficiency or the lifespan of the pump.

3.After the initial commissioning of water cooling system or the completion of water replenishment, it is recommended to reinstall the plug at the water replenishment port in a timely manner to ensure the sealing performance of the water cooling system and avoid the leakage of the coolant under unexpected conditions.

4.Ensure that spring hoop is placed on the joint when installing the water hose to avoid affecting the sealing performance of the water cooling system or causing the pipeline to fall off when pulled by external force.

5.It is recommended to start the long‐term operation of the server after the water cooling system is commissioned to avoid any malfunction of the server due to the high temperature of the chip. This process

may last for 20 minutes or so.

6.According to the air quality of the operating environment, it is recommended to dedust the heat exchanger of the Antminer S9 Hydro Hex regularly to ensure a good heat transfer performance.

7.Cooling water is recommended to refer to the requirements for water quality on our official website, or to purchase reliable distilled water or pure water to ensure that it will not deteriorate or corrode the pipeline during long‐term operation.

8.In order to ensure that the standard water pump can output sufficient flow to meet the heat dissipation requirements of the system at high temperatures, it is recommended that the hose length between the Antminer S9 Hydro Hex and the Antminer S9 Hydro server should not exceed 1 meter unless a pump with a larger head or flow is used.

9.If the customer purchases the water pump by himself, please remove the speed control signal line shown in the following figure before installation and ensure that the two wires are not short circuited so as to obtain a better heat dissipation effect.

10.When the pump is found to have a low flow rate during the exhaust operation, it may be because the gas inside the pump cannot be discharged normally, resulting in abnormal flow. The pump connector can be unplugged and restarted after the power is turned off, which is beneficial to the internal gas discharge of the pump. This operation may need to be repeated 2 to 3 times. It is recommended to operate before the server is started to avoid affecting the heat dissipation of the server.

Water Quality Requirements

S9 Hydro

In order to support the long‐term optimum operations of the water cooling system, we recommend that the water quality used should meet the requirements as stated in the table above.

S9 Hydro

Water‐cooling plates inside the server are welded parts made of aluminum, which have been cleaned before roll‐out. Water in some servers may appear to be turbid after running for a period of time. Kindly note that this will not affect on the overall cooling system and long‐term operation of the system.

B. Keep adding water. Since water is needed in both the server and the radiators, water in the pump will be reduced when the server is mining. Always remember to add water when starting the server to ensure that the water level is sufficient for optimal heat dissipation.

C. Antminer S9 Hydro server and radiators can be tilted left and right during water infusion which helps to ventilate the air.

S9 Hydro

After water circulation is running normally, Antminer S9 Hydro server and radiators can be slowly tilted left and right to help the residual air bubbles inside those two equipment to be discharged smoothly. This action can help to increase the cooling efficiency of the system.

D.Liquid Level: the standard level is as stated in the picture below. Please replenish the liquid promptly if the liquid level falls below the minimum value marking.
