Description
The Cisco NC57-18D12TH-SB= is a high-capacity spare scale line card bundle for the Cisco Network Convergence System 5700 Series, engineered for cloud-scale core, peering, and transport networks. It delivers 18 ports of 400 Gigabit Ethernet or flexible configurations supporting 200G and 100G speeds, enabling operators to scale bandwidth while preserving long-term investment protection.
Powered by advanced forwarding ASICs and enhanced memory resources, this scale line card supports massive routing tables, high-density interfaces, and advanced telemetry. Designed for pay-as-you-grow deployments, the spare bundle is ideal for rapid replacement, expansion, or lifecycle planning in mission-critical environments.
Built for modern service provider architectures, the NC57-18D12TH-SB= supports segment routing, MACsec, precision timing, and full integration with Cisco IOS XR Software, making it a robust choice for high-performance, high-availability networks.
