WS-C4948E-E Use Case
High-Density Data Center Leaf Aggregation with WS-C4948E-E Catalyst 4948E
In a global e-commerce data center, IT operations deploy the WS-C4948E-E Catalyst 4948E as a leaf switch to aggregate 48×10GbE server links and four redundant 40GbE uplinks. This configuration delivers sub-microsecond latency, micro-segmentation via Cisco TrustSec, and non-stop forwarding to sustain 24/7 transaction processing. Outcome: 60% higher east-west throughput, 40% lower packet loss, and simplified spine-leaf scaling under a single management pane.
Campus-Wide PoE+ Backbone for Smart Classroom and IoT Infrastructure
A university deploys WS-C4948E-E Catalyst 4948E switches across its smart campus to power 48 PoE+ endpoints per building zone (Wi-Fi 6 APs, VoIP phones, environmental sensors) with dual-stack IPv4/IPv6. Integrated Cisco Unified Power Over Ethernet ensures 740W per chassis with hot-swap power supplies. Outcome: Centralized remote power provisioning, 99.99% uptime for AV/IoT services, and 30% reduction in rack space and cable clutter.
Ultra-Low-Latency Fabric for Financial Trading and Virtualized Workloads
A financial institution integrates WS-C4948E-E Catalyst 4948E into its virtualized trading floor network to interconnect 48 virtual machine hosts at 10GbE with redundant 40GbE spine uplinks. Leveraging Cisco FabricPath and Priority Flow Control, the switch delivers deterministic sub-200μs latency and lossless traffic for high-frequency trading. Outcome: 25% faster order execution, seamless VM mobility, and end-to-end QoS guaranteeing SLAs for mission-critical applications.
