When you purchase a license for Server Enterprise Edition, you receive a License Key Card. This card is your paper copy of the Server Enterprise Edition license. It identifies the product name and the number of licensed users. It also has printed on it a license key, which enables you to install the license onto your system.
You install and manage your licenses using the License Administration utility, AppTrack. See the topics in Installing and Administering Server Enterprise Edition Licenses.
You can monitor the use of your deployment licenses. For details, see the topic Monitoring Server Enterprise Edition License Use.
