Cisco Catalyst 4500E Series 48-Port PoE and PoEP 10/100/1000 – High-Performance Enterprise Switch

Experience borderless, secure, and high-performance networking with the Cisco Catalyst 4500E Series 48-Port Switch. Built for the demands of modern enterprises, this switch delivers robust Layer 2-4 switching, energy-aware PoE power, and flexible scalability to support dense, evolving wired and wireless deployments. With its proven reliability, streamlined management, and Cisco’s trusted ecosystem, it enables secure mobility, video-enabled collaboration, and application-aware networking across today’s campus environments.

• High-density 48-port platform with PoE and PoE+ support: The Cisco Catalyst 4500E delivers a dense 48-port configuration designed to power a wide range of devices directly from the switch. With 802.3af PoE and 802.3at PoE+ support, IT teams can deploy IP phones, wireless access points, cameras, and other powered devices without requiring separate power sources. This reduces cable clutter, accelerates device rollout, and simplifies future upgrades while maintaining a centralized power management strategy that helps you monitor consumption and plan for growth.
• Borderless wired and wireless experience for mobile users: This switch is engineered to enable borderless unified networks that seamlessly integrate wired and wireless access. By aligning security policies, authentication, and traffic handling across both domains, the Catalyst 4500E supports mobile users with reliable performance whether they’re on a desk, in a meeting room, or roaming across the campus. The result is a consistent user experience for voice, video, collaboration apps, and real-time messaging, even as device density and traffic fluctuate throughout the day.
• Advanced Layer 2-4 switching with application-aware features: The Catalyst 4500E Series delivers robust switching capabilities across Layers 2 through 4, enabling precise traffic management and quality of service (QoS) for latency-sensitive workloads. With support for VLAN segmentation, ACLs, multicast, and QoS policies, you can prioritize business-critical applications, guarantee bandwidth for video and voice, and protect networks from congestion. This sophisticated feature set helps ensure predictable performance for time-sensitive workloads, optimize broadcast domains, and improve overall network efficiency.
• Energy savings and intelligent power management: Beyond simply delivering PoE power, the 4500E introduces energy-conscious features designed to reduce operating costs. By leveraging PoE power budgeting, dynamic power allocation, and efficient hardware design, it helps you scale PoE deployments while minimizing wasted energy. This makes it an attractive choice for deployments with large numbers of IP phones, cameras, and APs, where power usage can significantly impact the total cost of ownership without compromising performance or availability.
• Reliability, scalability, and Cisco ecosystem integration: Built on Cisco’s trusted platform, the Catalyst 4500E provides enterprise-grade reliability and compatibility with Cisco’s software tools and security features. Its architecture is designed to grow with your network, supporting additional modules, uplinks, and software-defined capabilities as your campus evolves. The switch integrates with Cisco management tools and analytics platforms, enabling centralized configuration, monitoring, and policy enforcement across the campus, which simplifies administration and accelerates problem resolution.

How to install Cisco Catalyst 4500E Series 48-Port PoE and PoEP 10/100/1000

• Prepare your installation space: Verify rack space, ventilation, and clearance for airflow around the chassis. Ensure the cabinet or rack is rated for the weight and that mounting rails are compatible with the Catalyst 4500E chassis. Have the appropriate mounting hardware, grounding strap, and cabling ready for a clean deployment.
• Mount and power: Secure the switch in the rack, connect the power supplies, and ensure proper grounding. If your model supports redundant power, connect both power supplies for high availability. Verify that power is stable before proceeding with configuration to prevent any boot-time issues.
• Connect network uplinks and PoE devices: Plan the port allocation for uplinks (to distribution switches, core devices, or wireless controllers) and for PoE-powered devices (phones, APs, cameras). Run CAT6/6A or higher cables to each port as required by your environment. Label cables for easier future maintenance and troubleshooting.
• Initial configuration and management access: Access the switch management interface via console, SSH, or a network management workstation. Configure the basic settings such as the device hostname, management IP, default gateway, and administrator credentials. Establish VLANs appropriate for your campus (e.g., voice VLAN, data VLAN) and define initial QoS and security policies to protect against unauthorized access and traffic spikes.
• Enable PoE on targeted ports and validate operation: Activate PoE on the ports that will power devices and monitor PoE usage to ensure devices boot properly without overloading the switch. Verify connectivity by testing device endpoints (phones, APs, cameras) for power delivery, network access, and service quality. Run baseline performance tests to confirm expected throughput and latency across the network, then document configurations for ongoing maintenance.
