Cisco NCS 540 SD-AR1K-N5Q2DSYS 2x400G 2x100G 24x25G | Router, Enterprise — SD-AR1K-N5Q2DSYS

Move large-scale traffic with fewer bottlenecks using the Cisco NCS 540 platform configured for dense high-speed aggregation. This hardware combines 2 x 400G QSFP-DD ports, 2 x 100G ports, and 24 x 25G ports to support high-bandwidth uplinks and access consolidation in demanding routing environments. Built for infrastructure teams that need capacity without wasting rack space, this model is suited to edge and aggregation deployments where interface mix matters. The 400G uplinks provide room for backbone growth, while the 100G and 25G ports support flexible service handoff and downstream connectivity. That balance makes it a strong fit for environments that need to scale traffic paths without replacing the platform too early. Because this listing is hardware-only and does not include software support, it is best suited for organizations standardizing on Cisco routing architectures and managing licensing or support separately. For teams comparing options, the value is in port density, interface speed, and the ability to anchor high-throughput designs with a compact routing platform. Ideal For Edge aggregation for service-provider routing High-capacity uplink consolidation in campus or metro networks Mixed-speed handoff for data center interconnect designs Routing platform standardization where software is procured separately Why This Product 1 Higher port density than lower-speed edge routers 2 400G uplinks support larger aggregation designs 3 Mixed 400G, 100G, and 25G interfaces improve deployment flexibility 4 Hardware-only model suits separate software and support procurement
