WS-X4904-10GE Use Case

Data-Center Aggregation with WS-X4904-10GE for 10GbE Uplink Scalability

In a mid-sized enterprise data center, IT architects deploy the WS-X4904-10GE Cisco 4900M Switch module in aggregation racks to consolidate four 10 Gigabit Ethernet uplinks from top-of-rack switches. This configuration delivers up to 40 Gbps of non-blocking throughput, reduces inter-rack latency to under 2 µs, and simplifies cabling. By centralizing high-density 10 GbE uplinks, organizations achieve predictable performance during peak application loads, streamline network operations, and eliminate port-sprawl—all while future-proofing for virtualization and storage-heavy workloads.

Campus Core Performance Enhancement with Cisco WS-X4904-10GE

A university IT department integrates the WS-X4904-10GE module into its Catalyst 4900M core switch to support surge video conferencing, VoIP telephony, and wireless-access backhaul across multiple buildings. With four dedicated 10 GbE ports, the campus core scales to aggregate traffic from 1 GbE edge switches, delivering line-rate throughput and sub-millisecond failover via hot-swappable design. The outcome: consistent Quality of Service for academic and research applications, simplified maintenance with redundant power and fans, and a 30 % reduction in network-related support tickets.

Service-Provider Metro Ethernet Peering Using WS-X4904-10GE

A regional telecom operator deploys the WS-X4904-10GE in its Cisco 4900M edge routers to terminate customer VLANs and Ethernet Virtual Circuits over fiber. Leveraging 802.1Q trunking and advanced QoS, each of the four 10 GbE ports aggregates multiple subscriber circuits with end-to-end SLA monitoring. This setup ensures sub-50 ms protection switching, 99.99 % service availability, and granular traffic policing for business-class Ethernet services. The operator expands revenue streams by offering tiered bandwidth packages without overhauling core infrastructure.
