You can set the information of the FortiExtender unit on the FortiGate in advance, and the unit is authorized and begins functioning when it is connected.
You can create an entry with an entry name no longer than 15 characters (saying extender1 as below), and the enter its serial number for "id". The extension-type will be auto-filled based on the attribute "id". For the FortiExtender 200F model without LTE/5G, the default is lan-extension; for models with LTE/5G, the default is wan-extension. You can change the extension-type as you want. Note that for FortiExtender 200F, it has only lan-extension. You can then select a profile that you have created before. If you have not created a profile before, type "end" and a default profile will be auto-geberated.
For details of the default extender profile, you can refer to the section of "Default FortiExtender profile".
