Important:
This procedure assumes that you are adding an Audio/Video (A/V) Conferencing Server pool to an already deployed environment. If you are deploying your A/V Conferencing Server in conjunction with a defined topology that has the A/V Conferencing Server or Servers already published, you should proceed to this topic: Install the Local Configuration Store.

To successfully complete this procedure, you can be logged on to the computer as a standard user. There are no special permissions or group assignments necessary to define the topology. To improve the A/V experience with a deployment of more than 10,000 users, we recommend that you deploy one or more stand-alone A/V Conferencing Servers. If necessary, review the hardware and software requirements for a stand-alone A/V Conferencing Server. For details about hardware requirements, see Server Hardware Platforms. For details about software prerequisites and requirements, see Additional Software Requirements.

You cannot convert an A/V Conferencing single computer pool to a multiple computer pool. If you later decide that your organization needs a pool with multiple computers, you must delete the single computer pool, and then add the multiple computer pool.

If you plan to implement an A/V Conferencing multiple computer pool in the future, select Multiple computer pool. Even though a pool is defined as two or more computers that are load balanced, you can create a single computer pool and create a pool fully qualified domain name (FQDN) for the single computer. When you are ready to add more computers to the pool later, you must re-run Topology Builder to define the new pool member, publish the new topology, and then set up the new A/V Conferencing pool member through the Lync Server Deployment Wizard. A/V Conferencing Server pools are unique in that they do not need load balancers to create a pool. A/V Conferencing pools load balance internally and do not need additional hardware.

To define a stand-alone A/V Conferencing Server with a single computer pool

  1. Log on to the computer where Topology Builder is installed.

  2. Start Topology Builder: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Topology Builder.

  3. On the Welcome page, click Download Topology from existing deployment, and then click OK.

  4. In the Save Topology As dialog box, choose a location, give the file an appropriate name, accept the default extension of .tbxml, and then click Save.

  5. Expand the Server Role tree view, right-click A/V Conferencing pools, and then click New A/V Conferencing Pool.

    New A/V Conferencing Pool menu

  6. On the Define the A/V Conferencing pool FQDN page, select Single computer pool, enter the FQDN, and then click Next.

  7. On the Associate Front End pools page, select the Front End pool that you want to associate with the new A/V Conferencing Server, and then click Finish.
