The only application server for the site.
The first of several application servers for the site.
Complete this procedure on the storage server.
Note Only assign one site to an application server.
Before you begin
Configure the storage and one or more application servers. See Chapter 3: Initial administration of the storage role and Chapter 4: Initial administration of the application role.
Create a site with one or more application servers. See Overview for administering sites.
Ensure that all application servers that you plan to add to the topology are running.
Procedure
- On the Administration menu, click .
- When the Topology Web page opens for the first time, the IP address defaults to the IP address of the storage server. Delete this IP address as follows:

Example
The following table is an example of a complete distributed topology with two sites, Atlanta and Boston. Atlanta has two application servers and Boston has one. 
Next Steps
If there is only one application server on your site, you are ready to administer users on the system.
If there are several application servers on your site, you must add the application servers to the system topology so that these application servers recognize each other. See Adding additional application servers.
