Your TE-1506 appliance ships without any pre-installed licenses. You can activate the included temporary licenses at a time of your choosing, and they remain valid for 60 days from the time of activation. You can run the `set license` CLI command to install subscription licenses. When you run the `set license` CLI command, you will be prompted to enter a license string. Contact Infoblox Support to obtain the license string and to go through the configuration process. You can run the `set temp_license` CLI command to install additional software (feature) licenses that last for 60 days. Running the `set temp_license` command displays a list of software licenses that can be installed on TE-1506. Depending on the software that you want to use, choose the license. The appliance then displays a list of appliances that can run the software you chose. Depending on your requirement, choose the appliance to install on top of the base TE-1506 appliance. The figure output depicts the list of licenses displayed and the appliances that support these licenses. The appliances vary depending on the base model that you have purchased.
