Cisco ASR 9900 A99-12X100GE-CM= 12-Port 100GE Line Card | Enterprise Router

Keep high-speed backbone capacity ready with the Cisco ASR 9900 12-Port 100GE Consumption Model Line Card, Spare. Designed for ASR 9900 deployments that need additional 100GE interfaces without redesigning the chassis, this line card helps preserve routing scale and service continuity in demanding carrier and enterprise core networks. Its 12-port 100GE configuration is suited to environments where uplink density and predictable expansion are critical. As a spare, it gives infrastructure teams a practical path to reduce downtime risk and maintain replacement readiness for production routers that carry aggregation, peering, or backbone traffic. This model fits buyers who value platform consistency and operational control. Instead of replacing the router or overprovisioning with lower-density options, you keep the ASR 9900 architecture intact and extend capacity where it is needed most. For teams managing expensive core assets, that translates into cleaner lifecycle planning and faster recovery when hardware maintenance is required.
