- Run the setup.exe file from the installation media to launch the SQL Server Installation Center.
- Click the Installation link on the bottom left. Click the Add node to a SQL Server failover cluster link. This runs the SQL Server 2022 Setup wizard.
- In the Product Key dialog box, enter the product key that came with your installation media and click Next.

- In the Cluster Network Configuration dialog box, enter the virtual IP address and subnet mask that the SQL Server 2022 failover cluster instance will use in the network subnet that the third node is in 10.65.32.0/19. Notice that the setup process also detected the existence of three network subnets. Since the virtual IP address for the 10.65.64.0/18 and 10.65.128.0/18 subnet has already been configured, that option has been disabled.
- In the Service Accounts dialog box, verify that the information is the same as what was used to configure the first node. Click Next.
