WS-C4948E-F-E Use Case
Data Center Top-of-Rack Aggregation with WS-C4948E-F-E ES
In a high-density data center rack, IT teams deploy the WS-C4948E-F-E ES (48×1G + 4×10G SFP+ AC PS FR EXT) as a Top-of-Rack aggregation switch. By linking 48 server NICs at 10/100/1000 Mbps with four 10 Gbps fiber uplinks to the core, this setup delivers sub-millisecond latency, non-blocking throughput, and hitless failover. Outcome: maximized east-west traffic performance, seamless VM migration, and improved SLA compliance for cloud workloads.
Enterprise Campus Core and Distribution Switch
A multinational enterprise configures the WS-C4948E-F-E ES in the campus core to interconnect floor-level distribution switches via its 4 SFP+ 10 Gbps ports and serve 48 Gigabit desktop and IP-phone endpoints. Leveraging advanced QoS, VLAN segmentation, and FR-EXT redundancy, the switch ensures predictable voice/video performance and rapid convergence under Spanning Tree or FabricPath. Outcome: scalable 1/10G uplink architecture, consistent user experience, and simplified network operations.
Industrial Edge Networking in Harsh Environments
A manufacturing plant deploys the FR-EXT-rated WS-C4948E-F-E ES on the factory floor to aggregate sensor networks, PLCs, and video surveillance cameras. Its wide-temperature range, redundant AC power supplies, and SFP+ uplinks to the control center maintain continuous 1 Gbps connectivity under extreme heat, vibration, and EMI. Outcome: zero unscheduled downtime, deterministic data collection, and compliance with industrial uptime requirements.
