Select this service for a Cisco 8711 1RU 12.8 Tbps P100 system where AR Level 3 hardware support is required. It is associated with the named Cisco 8711 platform and is not a router, interface module, or software package. The service scope explicitly excludes software support, making that boundary clear where hardware and software support are handled separately. Cisco SD-AR3K-8A7BFH1M names an AR Level 3 support option for the 8711 platform. The covered system reference includes the 1RU chassis format, 12.8 Tbps capacity designation, and P100 system designation. These details matter when matching support to an installed carrier-routing platform because the service references a specific chassis class and capacity configuration. Use the 8711 designation, 1RU form factor, 12.8 Tbps capacity, and P100 system reference when verifying platform alignment. This service differs from software-inclusive coverage by its stated exclusion of software support. It therefore addresses the AR Level 3 hardware-support requirement for the referenced system without adding a software-support entitlement.
