The Cisco Catalyst C9300-48UXM-E Multi-Gigabit Access Switch is a next-generation enterprise access-layer switch engineered to support the growing bandwidth demands of Wi-Fi 6/6E access points, high-performance workstations, and modern digital workplaces. As part of the Cisco Catalyst 9300 Series, this switch delivers exceptional throughput, advanced security, and scalable automation in a compact 1RU form factor.
The switch features 48 high-speed RJ45 access ports, including 12 Multi-Gigabit ports supporting 1G/2.5G/5G/10G speeds and 36 ports operating at 2.5Gbps, enabling seamless connectivity for devices that exceed traditional Gigabit Ethernet limits. With modular uplink flexibility, organizations can choose 1G, 10G, or 40G uplink modules to future-proof their campus edge.
Built on Cisco’s proven hardware architecture, the C9300-48UXM-E delivers a massive 880 Gbps switching capacity, 130.95 Mpps forwarding rate, and StackWise-480 technology, allowing up to 8 switches to operate as a single logical unit with 480 Gbps stack bandwidth. This ensures high availability, simplified management, and consistent performance across large deployments.
Running Cisco IOS XE with Network Essentials licensing, the switch supports Layer 2 switching, basic Layer 3 routing (static and RIP), IPv6, QoS, and comprehensive security features including 802.1X authentication, MACsec encryption, DHCP snooping, and Dynamic ARP Inspection. Integration with Cisco DNA Center, Plug-and-Play provisioning, and model-driven telemetry enables centralized management and automation.
Designed for enterprise reliability, the Cisco Catalyst C9300-48UXM-E supports modular redundant power supplies, redundant fans, and optimized back-to-front airflow, making it ideal for large campus networks, high-density wireless environments, and secure segmented access layers.
