Scalable, Flexible, 40 Gigabit Ethernet Switch

The Cisco Nexus 5648Q Switch offers scalability, high performance, investment protection, and flexibility for traditional, virtualized, and cloud environments. This two-rack-unit (2 RU) wire-rate, 24-port, 40 GE or 96-port 10 GE switch includes two expansion slots to help prepare your network for the future.

Save with 40-GE Modules

The Cisco bidirectional transceiver offers a cost-effective, 40 Gigabit Ethernet solution.

Features and Capabilities

The Cisco Nexus 5648Q Switch is optimized for:

  • Medium to high density Cisco Fabric Extender (FEX) aggregation
  • High-performance 40 and 10 Gigabit Ethernet server access
  • Converged Fiber Channel over Ethernet (FCoE) deployments

The Cisco Nexus 5648Q Switch offers the following benefits:

High Scalability and Performance
