Cisco Catalyst C9300-24UXB Ethernet Switch

The Cisco Catalyst 9300-24UXB is the flagship stackable enterprise switch designed to secure and accelerate modern networks across campuses, IoT deployments, and cloud-focused environments. Engineered for resilience, scalability, and intelligent automation, this switch blends Cisco’s proven security capabilities with the flexibility to support IoT devices, mobile users, and demanding cloud workloads. As the successor to widely adopted Catalyst platforms, the 9300 series brings a powerful combination of high performance, advanced policy enforcement, and simplified management that helps IT teams deliver continuous uptime and superior user experiences.

Built for a future-ready network, the C9300-24UXB combines enterprise-grade security, wired/wireless convergence, and software-defined management. It runs Cisco IOS XE, enabling consistent configuration and programmatic control across the network. With inline power for devices, resilient stacking, and energy-efficient design, this switch is well-suited for dense office floors, education campuses, retail branches, and data-center edge locations. The 24 fixed Ethernet ports deliver reliable access connectivity, while uplink options and stackability enable scalable, fault-tolerant deployments as your organization grows.

Designed to simplify operations, the C9300-24UXB integrates tightly with Cisco DNA Center for policy-based automation, centralized assurance, and rapid deployment. This level of integration helps network administrators accelerate onboarding of devices, enforce security postures, and monitor performance with real-time analytics. The switch’s security features guard against evolving threats at the edge, while its QoS capabilities ensure critical applications—voice, video, and collaboration—receive priority even in high-traffic environments. In short, this model delivers a robust, secure, and scalable platform that aligns with modern digital workspaces and cloud-oriented architectures.

• Security-first architecture: The C9300-24UXB is built to protect campus networks with strong authentication, access control, and encryption. Expect MACsec encryption, 802.1X-based authentication, and policy-driven segmentation that isolate devices and applications while reducing attack surfaces. This foundation supports secure IoT onboarding and compliant data handling across wired edge devices and networked endpoints.
• IoT and mobility readiness: Designed to accommodate a broad mix of IoT devices, cameras, IP phones, and wireless clients, the Catalyst 9300 emphasizes policy-based automation, robust QoS, and reliable performance for latency-sensitive applications. Its architecture enables precise traffic separation and scalable management so IoT deployments can grow without compromising security or user experience.
• Scalability and resilience: The 24UXB model is part of Cisco’s stackable Catalyst 9300 family, featuring StackWise-style stacking for simplified upgrades, centralized management, and high availability. Redundant power and fan options help maintain uptime, while firmware upgrades and policy changes propagate consistently across the stack.
• Cloud-informed management: With native IOS XE capabilities and seamless integration with Cisco DNA Center, administrators gain visibility, analytics, and orchestration across on-premises and cloud-connected networks. This enables faster provisioning, automated assurance, and reliable policy enforcement across large, distributed environments.
• Energy efficiency and sustainability: The Catalyst 9300 family emphasizes energy-conscious design, leveraging Cisco’s EnergyWise-compatible features and efficient hardware to reduce power consumption without sacrificing performance—an important consideration for large campuses and multi-site deployments.

How to Install Cisco Catalyst C9300-24UXB

• Plan your network topology, confirm rack space, power availability, and cooling for the 1U switch.
• Unpack the unit, verify model and accessories, and inspect for any shipping damage before installation.
• Mount the switch in a standard 19-inch rack, secure it, and connect the power supply(s) as required for your redundancy needs.
• Connect the 24 fixed Ethernet access ports to your device endpoints (workstations, phones, cameras, sensors) and attach the 4 x 10G SFP+ uplinks to your aggregation or distribution switches.
• Power up the unit and perform the initial setup using a console connection or SSH/telnet. Configure basic settings such as device hostname, management VLAN, and IP addressing for remote access.
• Enable PoE/PoE+ on required ports and configure VLANs, QoS policies, and security features (802.1X, MACsec) as needed for your environment.
• Integrate with Cisco DNA Center or your preferred management platform for centralized policy enforcement, monitoring, and automated orchestrations. Apply security baselines and verify connectivity across all segments.
• Test failover and stacking functionality by simulating a reset or removing a switch from the stack to ensure seamless traffic continuity and rapid recovery.
