Checking hardware connections
If there is no traffic whatsoever arriving to the FortiRecorder appliance, even though the configuration appears to be correct, it may be a hardware problem.
Verify that the LEDs for the ports light to indicate firm electrical contact when you plug network cables into the appliance. For LED indications, see your model’s QuickStart Guide.
If the cable or its connector are loose or damaged, or you are unsure about the cable’s type or quality, change it or test with a loopback jack.
If traffic ingresses and egresses but performance is not what you expect, verify that the MTU matches other devices on your network.
If the hardware connections are functional and the appliance is powered on, but you cannot connect — even using a local console connection to the CLI rather then a network connection — you may be experiencing bootup problems. Contact Fortinet Technical Support.
