How to Start an Automatic License Deployment for Registered Devices

If you want to ensure that the licensing process cannot be canceled by the user, create a profile in which System > Remote management > Prompt user on UMS actions is deactivated.
For further information about profiles, see the manual chapters Profile and Profile erstellen.

The profile must be based on exactly the same firmware version that is installed on the devices.

If applicable, assign the profile to the devices in question.

Go to UMS Administration > Licenses > Deployment and ensure that Enable automatic license deployment is activated.
Every 5 minutes, the UMS looks for registered devices without a valid license. If the UMS finds an unlicensed device, it orders a license from the licensing server. When ordering a license, the UMS sends the device's unit ID to the licensing server; each license is bound to the unit ID of a device.
The licensing server creates the licenses and sends them to the UMS. The UMS stores the licenses and adds a download link to the device settings.
Afterward, the UMS sends the current settings to the devices. When the devices have received the settings, they download their licenses from the UMS and reboot. After the reboot, the devices have all licensed features.

If a device cannot be reached by the UMS when it tries to send the new settings, it will not receive the new license immediately. But the device will handle this automatically by periodically asking the UMS if a license is available. If yes, it will get the current settings including the download link, download the license from the UMS, and reboot.
