WS-C4948E-F-S Use Case
Data Center Leaf Switch for Scalable Private Cloud Infrastructure
A global enterprise deploys the WS-C4948E-F-S Catalyst 4948E as a top-of-rack leaf switch in its 500-node hyper-converged private cloud. It terminates 48 1GbE server links and uplinks via four 10GbE SFP+ ports into the spine, leveraging wire-rate forwarding, advanced QoS and sFlow telemetry. Benefit: Delivers sub-50 µs latency, non-blocking east-west connectivity and real-time traffic insights, enabling predictable performance and seamless capacity expansion.
Campus Building Distribution for Unified Communications
In a 50-floor corporate headquarters, WS-C4948E-F-S switches aggregate 48 PoE+ connections per floor to power 200 IP phones and 80 Wi-Fi 6 access points, with four 10GbE uplinks into the core. Integrated TrustSec segmentation and policy-based QoS prioritize voice/video streams and isolate guest traffic. Benefit: Simplifies cable management, reduces separate power infrastructure costs, and enforces enterprise-grade QoS and security across the campus.
Edge WAN Aggregation for Financial Trading Resilience
A leading financial services firm installs WS-C4948E-F-S units at its secondary trading site to aggregate multiple carrier Ethernet circuits via four 10GbE SFP+ uplinks. The switch’s low-latency forwarding, granular NetFlow monitoring and hot-swappable fans enable sub-millisecond failover and strict SLA adherence. Benefit: Ensures ultra-low-jitter, high-availability connectivity for mission-critical trading platforms and streamlines disaster-recovery readiness.
