Changing the Edge pool associated with a Front End pool in Lync Server 2013
Topic Last Modified: 2012-09-21
If an Edge pool goes down but the Front End pool at the same site is still running, you will need to set the Front End pool to use an Edge pool at a different site until the failed Edge pool is restored.
In Topology Builder, navigate to the name of the Front End pool you need to change.
Right-click the pool, and then click Edit Properties.
In the Associations section, under Associate Edge Pool (for media components), use the drop down box to select the Edge pool you want to associate this Front End pool with.
