An E3 Server supports two license modes, Active License and Demo. A license mode is defined during server's initialization. If there is a valid protection device, Hardkey- or Softkey-type, E3 Server enters the Active License mode. If no device is detected, it then enters the Demo mode.

If a device changes, E3 Server compares the licenses on this new device with the licenses from the previous device and then performs the following adjustments:

•If the new licenses are exactly the same in terms of limitations of the ones on the previous device, they are applied immediately

•If the new licenses are less limited than the ones on the previous device, they are also applied immediately

•If the new licenses are more limited than the ones on the previous device, E3 Server waits two hours for the previous device to be reconnected. By the end of this period of time, if the licenses remain restrictive, the server is then restarted and the new licenses are applied
