Fortilink-Passive Firewall Fiber Interface Seen Down

[CEMS]

"Hello everyone, can you help me with an issue? I have 2 HA Active-Passive Firewalls, and the HA configuration is successful. I've connected 2 FortiSwitches to my Active Firewall using FortiLink, and I've also set up MC-LAG between the 2 FortiSwitches, which was successful. However, while the Active Firewall's connection to the FortiSwitches is fine, the connections from the Passive Firewall to the FortiSwitches show as down. Even though the SFPs and cables are correct, the ports on both the switch and firewall show no light. When I tried the same scenario with copper ports, the Passive Firewall can see the switches. Can you help me with this?"

Hi CEMS

Did you try to fail-over so the second firewall node becomes the active? What is the behavior in this case?
