2. Setting up the BITMAIN Antminer L7 Server
To set up the server:
Note:
The file IPReporter.zip is supported by Microsoft Windows only.
1. Download the following file: IPReporter.zip.
2. Extract the file.
Note:
The default DHCP network protocol distributes IP addresses automatically.
3. Right-click IPReporter.exe and run it as Administrator.
4. Select one of the following options:
Shelf, Step, Position – suitable for farm servers to mark the location of the servers.
Default – suitable for home servers.
5. Click Start.
The IP address will be displayed in a window on your computer screen.
6. In your web browser, enter the IP address provided.
7. Proceed to login using root for both the username and password.
8. In the Protocol section, you can assign a Static IP address (optional).
9. Enter the IP address, Subnet mask, gateway and DNS Server.
10. Click “Save”.
3. Configuring the BITMAIN Antminer L7 Server
Setting up the Pool
Best Mining Pools for Bitmain Antminer L7
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 been selected.
2. Set the options according to the following table:
| Option | Description |
| Mining address | Enter the address of your desired pool. Note: The L7 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. |
| Name | Your worker ID on the selected pool. |
| Password (optional) | The password for your selected worker. |
3. Click Save after the configuration.
