Description
The Cisco NCS 55A1-24H-B Network Convergence System router is a high-density, fixed-chassis platform designed for modern service provider, cloud, and large-scale data center networks. Built to support spine, leaf, and Top-of-Rack (ToR) architectures, it delivers exceptional throughput, scalability, and operational efficiency in a compact 1RU form factor.
Featuring 24 x 100 Gigabit Ethernet QSFP+ ports, the NCS 55A1-24H-B supports advanced routing and transport technologies including MPLS, Segment Routing, and L3VPN. With up to 1.8 Tbps of system throughput and support for up to 2 million FIB entries, it is optimized for high-performance IP and converged networks.
Powered by Cisco IOS XR, the platform provides carrier-class reliability, programmable telemetry, zero-touch provisioning, and robust security features such as MACsec, ACLs, and AAA. Dual redundant power supplies and hot-swappable fan trays ensure high availability for mission-critical deployments.
