For each new version of cadett ELSA, the hardware lock needs to be updated. This prevents unauthorised usage of versions when no license has been purchased.

 

If you are using a network based hardware lock and need to add new licenses, you might not need to get a new physical hardware lock. An update of the existing hardware lock, like for new versions, might be sufficient. The procedure is the same.

 

Each network hardware lock has a maximum number of licenses that it can contain. As long as the total number of licenses is lower than or equal to that maximum number, you can add licenses without physically replacing the lock.

 

Please refer to the sub-topics that are listed below for details about how you perform the update.

 

•General procedure
