# Step 11. Specify Veeam ONE Server Connection Details

At the **Server Connection** step of the wizard, specify settings that the Web Services component must use to connect to the Server component:

- In the **Veeam ONE** **server** field, specify a FQDN of a machine on which you have installed the Veeam ONE Server component.
- In the **Veeam ONE** **Web API port** field, specify the number of a port that the Web Services component will use to communicate with the Veeam ONE Web API component.

  The default port number is `2741`.

- In the **Username** and **Password** fields, specify credentials of a user under which Veeam ONE Web Services will connect to Veeam ONE Server and configure it during installation.

  The user must be a member of *Veeam ONE Administrators* security group on the machine where Veeam ONE Server is installed.

  The user name must be specified in the *DOMAIN\\USERNAME* format.
