Reading the TechNet article, Installing Edge Servers, it’s pretty straightforward to deploy the Lync Edge server role in your Lync topology.
While updating my demo environment with an Edge server, I followed the step-by-step guidance from the article, and made some print screens on the way.
1. Log on to the computer on which you want to install your Edge Server as a member of the local Administrators group or an account with equivalent permissions.
2. Ensure that the topology configuration file you created using Topology Builder, and then exported and copied to external media, is available on the Edge Server (for example, on the Edge Server, attach the USB drive onto which you copied the topology configuration file, or verify access to the network share where you copied the file).
In order to export your Lync server 2010 topology, policies, and configuration settings to a file, you can run the Lync shell cmdlet Export-CsConfiguration, and specify a file name and file location after the parameter FileName.
3. Start the Deployment Wizard.
4. In the Deployment Wizard, click Install or Update Lync Server System.
5. After the wizard determines the deployment state, for Step 1. Install Local Configuration Store, click Run and then do the following:
6. In the Deployment Wizard, click Step 2: SetUp or Remove Lync Server Components to install the Lync Server edge components specified in the XML configuration file that is stored on the local computer.
7. After completing the installation, use the information in Set Up Edge Certificates to install and assign the required certificates before you start services.
That’s all
