FortiGate unit Operation widget
The Unit Operation widget is an illustrated version of the FortiGate unit’s front panel that shows the status of the FortiGate unit’s network interfaces. Interfaces appears green when connected. Hover the mouse pointer over an interface to view further details.
Icons around the front panel indicate when the FortiGate unit is connected to a FortiAnalyzer or FortiManager device, or FortiClient installations. Select the icon in the widget to jump to the configuration page for each device. When connected to one of these devices, a green check mark icon appears next to the icon. If the device communication is configured but the device is unreachable, a red X appears.
