Cisco ASR 9000 A9K-MOD400-CM= 400G Line Card | Router Module

Increase routing capacity without changing the operating model of your core network. The Cisco ASR 9000 Modular 400G Consumption Model Line Card is built for modular ASR 9000 deployments that need higher bandwidth density and predictable expansion planning. It fits environments where traffic growth is measured in backbone pressure, not branch counts. This line card is suited to service-provider and large enterprise edge architectures that depend on chassis-based routing, centralized control, and long service life. By extending the ASR 9000 platform with 400G-class capacity, it helps preserve investment in existing infrastructure while supporting higher throughput demands across aggregation, metro, and core layers. For teams standardizing on Cisco routing, the value is in platform continuity: fewer architectural shifts, cleaner capacity planning, and a path to scale that stays aligned with established operational processes. It is the kind of component selected when uptime, density, and long-term network design discipline matter more than short-term hardware savings.
