3.Configuring the Bitmain Antminer KA3
Setting up the Pool
To configure the server:
1. Click Settings marked below:
Note:
- Fan speed percentage can be adjusted, but we recommend to keep the default setting. The server will adjust the fan speed automatically if the fan speed percentage has yet to been
- There are two working modes of Bitmain Antminer KA3 server: Normal mode and Sleep. The server enters the sleep mode under the condition that the control board is powered while hashboards are not powered.
2. Set the options according to the following table:
| Option | Description |
| Mining address | Enter the address of your desired pool. Note: The Bitmain Antminer KA3 servers can be set up with three mining pools, with decreasing priority from the first pool (pool 1) to the third pool (pool 3). The pools with low priority will only be used if all higher-priority pools are offline. |
