Network licenses are distributed from the License Server. The License Server shares a predetermined number of simultaneous instances that are available network-wide. To start licensed clients and SmartStruxure servers using network licenses, the required number of licenses have to be available on the License Server.
To check out a network license from a License Server, you have to define the License Server address where network licenses are available for checkout. You define the address to the License Server when installing the licensed product. You edit the License Server address either in the Windows registry or in License Administrator, on the computer or SmartStruxure server that hosts the licensed product.
A checked out network license is not physically moved to the client or SmartStruxure server. The checked out license is allocated in the License Server until the license is released by the client or SmartStruxure server.
When a licensed WorkStation, Enterprise Server, or client tool starts and no local licenses are activated, the WorkStation or Enterprise Server searches the License Server for an available network license. If an available network license is found, the licensed product checks out the license and starts. If no licenses are available, the licensed product does not start. When the application is closed, the license is checked in on the License Server.
On the SmartStruxure server running both the License Server and the Enterprise Server, use the address @localhost so the Enterprise Server does not connect to the License Server through the network.
