Embedded in the Catalyst 3560 is the Cisco Cluster Management Suite (CMS) Software, which allows users to simultaneously configure and troubleshoot multiple Cisco Catalyst desktop switches using a standard Web browser. Cisco CMS Software provides configuration wizards that greatly simplify the implementation of converged networks and intelligent network services.

The Catalyst 3560 Series can provide a lower total cost of ownership (TCO) for deployments that incorporate Cisco IP phones and Cisco Aironet wireless LAN access points, as well as any IEEE 802.3af-compliant end device. Power over Ethernet removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling that would otherwise be necessary in IP phone and wireless LAN deployments. Maximum power availability for a converged voice and data network is attainable when a Catalyst 3560 Switch is combined with the Cisco Redundant Power System 675 (RPS 675) for seamless protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages.

The Cisco Catalyst 4500 Series offers nonblocking Layer2/3/4 switching with integrated resiliency, further enhancing control of converged networks. Converged voice/video/data networks with high availability enable business resiliency for enterprise and metropolitan (metro) Ethernet customers deploying Internet-based business applications.

Integrated resiliency enhancements offered in the Cisco Catalyst 4500 Series include integrated inline power for IP telephony, software-based fault tolerance, and 1 + 1 power supply redundancy. Integrated resiliency in both hardware and software minimizes network downtime, ensuring workforce productivity, profitability, and customer success. As a key component of Cisco AVVID (Architecture for Voice, Video and Integrated Data), the Cisco Catalyst 4500 extends control to the network edge with intelligent network services, including sophisticated quality of service (QoS), predictable performance, advanced security, comprehensive management, and integrated resiliency. Offering compatibility with Cisco Catalyst 4000 Family line cards and supervisor engines, the Cisco Catalyst 4500 Series enables an extended window of deployment for the Cisco Catalyst 4000 Family in converged networks. This reduces the cost of ownership by minimizing recurring operational expenses, thus improving return on investment (ROI).
