### Selecting License Classes to Provide

A 'License Class' is a particular version of a particular licensed product. For example, Plesk 7.5 Reloaded (TM). Licenses are issued in the frame of a license class, starting from a single license and up to a license pack that includes several identical licenses.

After all the data necessary for new Parallels Key Administrator (KA) plug-in configuration is saved, Parallels Business Automation - Standard starts executing a special task that fetches the list of license classes allowed for this particular plug-in. Only after the list of license classes is fetched a KA plug-in is considered as configured and gets a 'Configured' status, i.e., ready for use. The list of license classes appears under the License Classes and Properties tab within a plug-in configuration settings.

The set of license classes is read-only in respect to the number of license classes, their composition and each class properties.

For offline Parallels Key Administrator (KA) plug-in configurations the set of license classes available is taken from the Parallels Business Automation - Standard database and in this case, the license classes list normally includes all license classes available at Parallels KA. For offline KA plug-ins you must manually select the license classes to sell, in accordance with the client agreement you have completed with Parallels KA.

For offline KA plug-in configurations the set of license classes available can be changed (for example, new classes can be added to the list) by installing a simple upgrade. The upgrade is developed and conducted by Parallels.

For online KA plug-in configurations the set of license classes available is fetched online after a plug-in is configured from the KA server and in this case, the set of license classes will automatically correspond to your KA client agreement, because it is checked by your client login and password. Online KA plug-in configuration allows updating the list of license classes online. In this case, if Parallels Key Administrator has started supporting new license classes, they appear in the list, and if some license classes support has been discontinued, such license classes are removed from the list. Existing configuration of license classes availability stays without changes. To update the list of license classes online, use the Reconfigure button located below the list of license classes.

You can enable a license class to make it possible to include the corresponding licenses in hosting plans and sell them. Please note that only enabled license classes can be included in hosting plans.

Each license class can include a variety of license types (for example, different number of domains for Plesk licenses), additional features, and additional keys. Additional keys are complementary licenses that can be sold together with license that belongs to a license class. A license class configuration with all its features and additional keys (if any) is visible from hosting plan settings, under the Licenses tab or at the 'Licenses' step in a hosting plan creation wizard.

To make licenses of a particular class available for sale:

1. Select Service Director - License Manager - Plug-Ins. The list of all configured KA plug-ins appears on the screen.
2. Click on the name of the KA plug-in you would like to configure license classes for.
3. As the KA plug-in settings appear on the screen, click on the License Classes and Properties tab.

   Note: If you have selected a KA plug-in configured to get licenses online, the list of license classes can be updated online. To this effect, click the Reconfigure button located at the bottom of the list. Offline KA plug-ins do not have such a button.

4. Scroll the list of license classes that appears on the screen up to the end and click the Edit button.
5. To allow a license class for selling, check the box next to a license class name. To disable a license class for hosting plans, clear the box next to a license class name.
6. To save changes, click the Update button.
