Keep metro, edge, and aggregation traffic on a platform sized for high port density and fast uplinks. The Cisco NCS 540 28x10G 4x100G DC combines 28 x 10G interfaces with 4 x 100G ports, giving network teams a practical way to terminate large numbers of access circuits while preserving headroom for upstream growth. This model is a strong fit when you need carrier-grade routing in a compact footprint and want to avoid overbuilding with a larger chassis. The 100G uplinks help prevent bottlenecks as traffic rises, while the 10G access ports support dense service delivery at the edge. DC power aligns with telecom and data center deployments where centralized power design and predictable integration matter. For infrastructure teams, the value is in matching port mix to real traffic patterns: enough 10G density for aggregation, enough 100G capacity for backbone handoff, and a platform designed for service-provider environments where uptime and routing consistency are non-negotiable.
