2. Starting Your Miner

2.1 Preparatory Work

Prepare a network cable, a Miner A1, a power supply unit, an AC power cord and a computer.

2.2 Connecting the Power Supply

Ten PCI-e connectors are located at the top of the Miner A1 for connecting the PSU. Nine

PCI-e connectors are for the hash boards and each hash board has a set of three PCI-e connectors.

One PCI-e connector located on the controller is for the controller. (See figure 1 in part 1.1)

To connect the power supply :

1) Connect PSU power cable connectors to each of the eight PCI-e connectors on the top of the miner and the PCI-e connector on the controller.

2) Connect the network cable to the ETH port.

3) Check whether the flexible extension cables and the fan connection cable and regulated power supply socket on the top of the miner are connected properly.

4) After all cables have been connected correctly, connect the AC power cord to the power

After connecting the power supply, please check whether the miner operates as follows :

1) the front and rear fans operate normally;

2) the green light on the controller twinkles;

3) the green light on the ETH port keeps on and the orange one twinkles;

4) the blue lights on the three sets of hash board PCI-e connectors keep on.

If the miner runs normally, you can move to the next step. If not, please troubleshoot the miner.

3. Setting Up Your Miner
