In my preceding post, I have covered step by step deployment process of Front End server pool. This post covers the step by step process to deploy mediation server pool. You need to make sure your FE pool is up and running and follow the process as given below.

Join all the mediation servers to domain and login to first mediation server.

Open PowerShell and add following features.

Add-WindowsFeature NET-Framework-Core, RSAT-ADDS, Windows-Identity-Foundation, NET-WCF-HTTP-Activation45, Web-Asp-Net45 -Source D:\sources\sxs

Run windows update (KB2982006).

Install Silverlight.

Insert Skype for Business Server 2015 media and run setup.exe.

Run “Install Administrative Tools”

Open Topology Builder and add mediation server pool.

Once Mediation Server Pool is added with at least one mediation server, publish the topology.

Open Deployment Wizard and run “Install or Update Skype for Business Server System”

Run “Install Local Configuration Store”

Run “Setup or remove Skype for Business Server Components”

Run “Request, Install or Assign Certificates”

Request Certificate.

Fill the required fields and click on Advanced.

Write friendly name and select “Mark the certificate’s private key as exportable”

Add other mediation servers which are going to be part of your mediation pool.

Click on Next.

Now assign the certificate.

Once certificate is assigned, close the window.

Part II of this post covers installation of adding mediation server to an existing mediation pool.
