Maintain a defined three-year SD-WAN monitoring service term for the GT51G-associated platform. Fortinet FC-10-GT51G-288-02-36 is a service subscription focused specifically on SD-WAN monitoring, providing the service period stated by the ordering code rather than a physical network appliance. SD-WAN environments often connect branch, campus, cloud, and data-center resources across multiple WAN paths. Monitoring is the operational function used to track that SD-WAN environment over time. This service is suited to deployments that need an established monitoring term associated with the GT51G platform designation, including sites where SD-WAN connectivity is already part of the network architecture. The defining characteristic of this subscription is its three-year duration and SD-WAN monitoring scope. It is not a general hardware option or a port expansion item; it applies to the monitoring service category associated with the specified platform code. Select this service where the required coverage period is three years and the intended service function is SD-WAN monitoring. The electronic service classification also makes it distinct from physical Fortinet appliances, modules, and accessories.
