Perform basic setup

The network in the A-Data Center is physically isolated from the Selectel shared networks, because of this, the network and server operating system can be managed through the control panel impossible.

Connect to the server via SSH or RDP is only possible after basic configuration. Basic configuration on the server in the A-DC is performed via IPMI.

1. Forward the ports to access the IPMI server.
2. If the server does not have an operating system installed, install it from your image via IPMI server.
3. Configure the network interface on the server.
4. Optional: forward the server's ports to the Internet.

1. Forward ports for IPMI access⁠

Port forwarding is performed on the firewall. The list of ports that are used in the work, the purpose of their use and their default values can be viewed in the table below Used ports.

1. Open the page in your browser:

   https://<ip_address>:<port>

   Specify:

   • <ip_address> — The IP address of the firewall;
   • <port> — connection port.

2. Enter the login and password that we send in the ticket after the firewall order.

3. Route the IPMI ports for Virtual Media and IKVM Server to the Internet.

   The port in the firewall rule must match the port in the server's IPMI settings. For example, if you specified port 8443 in the firewall rule for HTTPS access, then specify port 8443 in the server settings as well.

   Use the instructions depending on your firewall:

   • for FortiGate — Configure port forwarding;
   • for UserGate — NAT and routing in the UserGate documentation.

Used ports⁠

	Web SSL Port	IKVM Server Port	Virtual Media Port	Web Port*
Purpose of use	Access to the GUI via HTTPS protocol	Console access	Downloading ISO	Access to the graphical interface via HTTP protocol
Default value	443	5900	623	80

* For security reasons, we recommend disabling Web Port when configuring the firewall.

2. Install the operating system from your image⁠

OS installation for the server in the A data center is performed via IPMI.

1. Save the OS image in the format .iso on the local computer from which you will connect to the server via IPMI.
2. Open the IPMI server page in your browser.
3. Authorize in the web interface of the IPMI server with the data we send in ticket c service provision.
4. Go to the section Remote Control → Console Redirection.
5. Click Launch Console. Remote Console opens. If Remote Console does not open, save the proposed Java file, run it, and confirm the security exception.
6. Go to the section Virtual Media → Virtual Storage.
7. Open the tab Device 1.
8. In the field Logical Drive Type select the image type — ISO File.
9. In the field Image File Name and Full Path select the distribution file in the format .iso.
10. Click Plug In. The image will be connected.
11. Click OK.
12. Open the tab Power Control.
13. Click Set Power Reset. The server will be rebooted.
14. When restarting the server, change the boot order and specify booting from Device 1.
15. Go through all the steps of installing the OS.
16. When the OS is installed, disable the image via IPMI by opening the tab Device 1 and press Plug Out.
17. Restart the server.

3. configure the network interface on the server⁠

1. Open the IPMI server page in your browser.
2. Authorize in the web interface of the IPMI server. Connection data can be viewed in ticket c service provision.
3. Go to the section Remote Control → Console Redirection.
4. Click Launch Console.
5. The Remote Console opens. If Remote Console does not open, save the suggested Java file, run it, and confirm the security exception.
6. Authorize OS.
7. Configure the network interface on the server.

4. Forward server ports to the Internet⁠

Port forwarding is performed on the firewall. To connect to the firewall, use the data we send in the ticket after the firewall order.

After port forwarding, you can connect to the server, firewall, and IPMI using the same IP address with different ports. If public addresses from a dedicated subnet are used for the servers, you can connect to the servers using them. For IPMI interfaces, we recommend using a private subnet and restricting access only from trusted addresses.

1. Open the page in your browser:

   https://<ip_address>:<port>

   Specify:

   • <ip_address> — The IP address of the firewall;
   • <port> — connection port.

2. Route the IPMI ports for Virtual Media and IKVM Server to the Internet. Use the instructions depending on your firewall:

   • for FortiGate — Configure port forwarding;
   • for UserGate — NAT and routing in the UserGate documentation.
