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.

Frequently asked questions

  • Q: What ports and speeds does the Cisco Catalyst 4500E 48-Port switch provide? A: It offers 48 RJ-45 ports that support 10/100/1000 Mbps speeds, with PoE and PoE+ on eligible ports to power connected devices without separate power adapters.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.
