Standard Edition Server Cumulative Updates
To apply the latest cumulative updates to a Standard Edition Server, all you need to do is run LyncServerUpdateInstaller.exe and click on Install Updates. The installer will detect what Lync services have been installed on the server and will display whether or not the latest update has been applied.
Once the updates have been installed, restart the server if prompted to do so and then Install Lync Database Updates. You apply the update by running the following PowerShell cmdlet on all Standard Edition Servers in your environment:
Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn FEBE.FQDN -Verbose
