Cisco Modular Switches Cisco modular switches include the Cisco Catalyst 4500-E Series and Cisco Catalyst 6500 Series Switches for the campus and Cisco Nexus 7000 Series Switches for the data center. With a broad selection of supervisors, line cards, service modules (Catalyst 6500), fabric modules (Nexus 7000), and power supplies, these intelligent platforms deliver optimal flexibility to meet ever-changing requirements for deploying numerous, concurrent intelligent services without degrading the overall performance of the switch. These extensive product portfolios allow customers to build an infrastructure that can be scaled cost-effectively with energy, budget, and resource efficiency. Customers can simplify the transition to 10, 40, and 100 Gigabit Ethernet, handle architectural changes to support virtualization, mobility, video, and cloud computing as well as support converged applications in a secure architecture. Cisco modular switches support features such as the Cisco Virtual Switching System and virtual device contexts to simplify management and deliver operational continuity with high availability and near zero downtime. Critical redundant hardware and software features deliver the highest resiliency for all places in the network. Modular switches also provide the highest levels of investment protection, allowing cost effective incremental upgrades to supervisors, line cards and fabric modules while minimizing the need for disruptive fork-lift upgrades. 85
