Cisco Catalyst 4000 Series Used

The Cisco Catalyst 4000 Series of modular switches include the Cisco Catalyst 4003 and Catalyst 4006 chassis. As a key component of Cisco AVVID (Architecture for Voice, Video, and Integrated Data), the Cisco Catalyst 4000 Series extends control from the backbone to the network edge with intelligent network services including advanced quality of service (QoS), scalable performance, comprehensive security, and simple manageability. The modular architecture, media flexibility, and expandability of the Cisco Catalyst 4000 Series enable a longer deployment life in converged networks. A longer deployment life reduces the overall cost of ownership by minimizing recurring operational expenses and also improves return on investment (ROI).

Cisco Catalyst 4500 Series Used

• Secure unified communications offers extensive integrated services and features to optimize and scale the network:
  • Power over Ethernet (PoE): Get comprehensive support for a broad range of PoE end devices, including 802.11n wireless access points, and up to 30W PoE per port for future applications.
  • Intelligent services: Optimize and secure your network with hardware-based quality of service, multicast, security, IPv6 and integrated management features
  • Scalability: Grow your network and services with up to 384 PoE ports, up to 34 10 Gigabit Ethernet capability, and ample hardware resources to support concurrent services.
• Resiliency: Hardware and software based resiliency features minimize planned and unplanned network downtime
  • Hardware resiliency: All critical components, such as supervisors, power supplies, and fans, are redundant.
  • Software resiliency: Subsecond supervisor switchover (SSO) and Cisco In Service Software Upgrade (ISSU) occur without dropping IP calls.
  • Extensive security features: Network disruptions from security threats are minimized.
• Simplified operations designed to lower total cost of ownership for first-time configurations, ongoing operations, and troubleshooting:
  • Embedded Event Manager (EEM): Simplify both routine and extraordinary events with a customized approach to EEMevent detection, recovery, and automation.
  • Operational features: Minimize operational and troubleshooting tasks with CPU monitoring, Cisco ISSU, IOS IP SLA, Smartports, AutoQoS, Remote Switched Port Analyzer, Link Layer Discovery Protocol-Media Endpoint Discovery, Discovery Protocol, and CiscoWorks.
  • Hot-swappable components: Supervisor, line cards, power supplies, and fan tray are hot-swappable.
• Investment protection - Extensive investment protection with backward and forward compatibility across Cisco Catalyst 4500 Series generations dating back to 1999, maximizing return on investment:
  • Backward and forward compatibility: Mix new Cisco Catalyst 4500 E-Series line cards and classic line cards in the same chassis without performance degradation.
  • Investment enhancement: Upgrade currently deployed classic line card features with a simple upgrade to the Cisco Catalyst 4500 Supervisor Engine 6-E.IPv4 and IPv6: The switch is optimized for simultaneous IPv4/IPv6 deployment or migration.
