I'm trying (and failing badly) at setting up a TL-SG3452XP remotely in the EMEA region, from the US - we used a TL-SG3428MP as a local testing environment with minimal issue (after help with this community!)

Connection:

FortiGate 60F, port 1 - configured to send DHCP 10.50.1.80-200 > TL-SG3452XP, port 1 (set for VLAN 1400, defined in the relay with 10.50.1.1 as the server)

TL-SG3452XP configured as we tested, with DHCP & VLAN relays, working correctly as far as we can tell (devices plugged into the TL-SG3452XP obtain an IP address).

The current issue is: how do I set the TL-SG3452XP to a static IP address in the 10.50.1.x range? If I set the VLAN (either management VLAN 1 or the created VLAN 1400) to a static IP (or secondary IP) the switch becomes inaccessible until it's rebooted (been making changes without saving until we know it works).

The other issue is the switch is DHCP hopping and consuming IP addresses?

This is a new behavior that showed up during troubleshooting this morning.

Do I need to just reset / wipe the switch then start over? Forget DHCP in the FortiGate and move it to the TL-SG3452XP? (is this a possible option? We're intending to connect three APs to the switch, which need to give two IP ranges for internal and guest AP connections).

Thanks in advance.
