Good mornign 

I have a TL-SG3452P Switch and I want to replace Cisco old device.

I have a OMADA Controller with several AP already configured in my laptop on VLAN 1.

Also, I use a Fortigate 60 F as Router.

- VLAN 1 for admin connection

- VLAN 100 for ethernet connections -> Users

- VLAN 300 for WIFI devices -> Users

- VLAN 15 for Guest 

I try to connect the Switch an link the firewall on the port 1 on the switch to port 1 on the FW, but the controller cannot detect the switch to adopt it.

1- How I must do to see the Switch on the controller.
2- How I must configure the controller to connect the Switch with the FW and set the VLAN on the ports.
