Cisco NCS540 N540-ACC-SYS= 24x10G SFP+ | Service Provider, QSFP28 — N540-ACC-SYS=

Keep traffic consolidation simple as access and aggregation demands rise. Cisco NCS540 N540-ACC-SYS= brings a dense mix of 10G, 25G, and 100G optics into a single service-provider platform, giving network teams room to scale without redesigning the edge. The port mix is the point: 24 x 10G SFP+ ports handle established services, 8 x 1/10/25G SFP+/SFP28 ports support flexible uplinks and staged upgrades, and 2 x 100G QSFP28 ports provide higher-capacity handoff where backbone or peering links demand it. That combination helps preserve investment in existing optics while creating a clean path to higher throughput. For providers carrying latency-sensitive or revenue-generating workloads, the value is in controlled growth. You can segment traffic, extend service life, and align port speeds to actual demand instead of overbuying capacity too early. This model is suited to environments where port density, speed diversity, and operational continuity matter more than commodity switching. It is a practical choice when the cost of a network change includes not just hardware, but service disruption and migration risk. Ideal For Service-provider aggregation at the metro edge Mixed-speed uplink consolidation in carrier networks Capacity expansion for access and handoff layers Migration from 10G services to 25G and 100G transport Why This Product 1 Higher port diversity than fixed-speed edge platforms 2 Supports 10G, 25G, and 100G migration in one chassis 3 Better suited to staged upgrades than single-speed alternatives 4 Built for service-provider aggregation rather than general office switching
