2. Connecting to the Power Supply
Ten PCI-e connectors are located at the top of the Antminer S9i server for connecting the PSU as follows:
- Nine 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 hash board 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 S9i server, ensuring that each hash board is powered by the same PSU.
2. Front fan (intake fans); B. Rear fan (exhaust fans); C. Miner model; D. Serial number (SN) of miner, to review warranty status; E. Estimated hash rate of miner model; F. Rear fan connector; G. Front fan connector; H. Chain #8 connector; I. Chain #7 connector; J. Chain #6 connector; K. 6-pin power connector; L. Control board chain connector; M. 6-pin power connector
3. Connect a PSU power cable connector to the Antminer S9i PCI-e connector on the controller.
4. Connect the network cable to the ETH port.
5. To power up your Antminer S9i 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. Setting Up Bitmain Antminer S9i Server
To set up the server:
The file IP Reporter.zip is supported by Microsoft Windows only.
1. Download the following file: IPReporter.zip
2. Extract the file. 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 theservers.
- Default – suitable for home servers.
5. Click Start.
6. On the controller board, click the IP Report button. Hold it down until it beeps (about 5 seconds).
The IP address will be displayed in a window on your computer screen.
7. In your web browser, enter the IP address provided.
8. Proceed to login using root for both the username and password.
9. In the Network section, you can assign a Static IP address (optional).
10. Click Save & Apply.
4. Configuring Bitmain Antminer S9i Server
Setting Up the Pool
To configure the server:
1. click General Settings. (Here takes Antminer S9i-14T running under the firmware with “Normal” mode as an example)
2. Set the options according to the following table:
| Option | Description |
| Pool URL | Enter the URL of your desired pool Note: The Antminer S9i server 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. |
| Worker | Your worker ID on the selected pool. |
| Password | The password for your selected worker. |
3. Click Save & Apply to save and restart the server.
5. Monitoring Bitmain Antminer S9i server
To check the operating status of your server:
1. Click the status marked below. (Here takes Antminer S9i-14T running under the firmware with “Normal” mode as an example)
2. Monitor your server according to the descriptions in the following table:
| Option | Description |
| ASIC | Number of chips detected in the chain. |
| Frequency | ASIC frequency setting. |
| GH/S(RT) | Hash rate of each hash board ( GH/s) |
| Temp(PCB) | Temperature of each hash board (°C).(Applied only to server with fixed frequency) |
| Temp(Chip) | Temperature of the chips on each hash board (°C). |
| ASIC status | One of the following statuses will appear: o O – indicates o X – indicates error o – indicates dead |
Note: The Antminer S9i server is with automatic frequency. Firmware will stop running when the Temp (PCB) reaches to 90℃，there will be an error message “Fatal Error: Temperature is too high!” shown in the bottom of kernel log page.
