Cisco ASR 9000 400GE Service Edge Combo Line Card 5th Gen | Router — CON-SSSNT-A9K4HGFS

Push more traffic through the service edge without redesigning the platform. The Cisco ASR 9000 400GE Service Edge Combo Line Card 5th Gen is built for operators that need high-capacity forwarding in a compact line-card form factor, with the integration expected from the ASR 9000 family. This line card is suited to backbone, metro, and aggregation environments where port density and throughput must stay aligned with subscriber growth, east-west traffic, and peering demand. Its 400GE focus makes it a strong fit for networks that need to consolidate uplinks, preserve rack space, and keep latency-sensitive services on a stable forwarding path. For teams standardizing on Cisco service-provider routing, this card helps extend the life of the chassis investment while supporting higher-speed interfaces at the edge. It is the kind of component chosen when lower-capacity alternatives would force earlier refresh cycles or create bottlenecks in a critical path. If your design calls for service-edge scale with room to grow, this line card belongs in the shortlist. Ideal For Service-provider edge routing in metro aggregation networks High-bandwidth uplink consolidation in carrier backbones Chassis expansion for ASR 9000 platform deployments Capacity upgrades for traffic growth at the network edge Why This Product 1 Higher-capacity 400GE service-edge connectivity than lower-speed line cards 2 Chassis-based design supports platform expansion without full router replacement 3 Built for carrier and metro aggregation workloads, not general-purpose switching 4 Cisco platform alignment helps standardize operations across service-provider networks
