The C9300-48UN-E represents the pinnacle of Cisco’s flagship Catalyst 9300 Series stackable access platform. Engineered for the demands of a modern, hybrid world, this switch goes far beyond traditional network connectivity. It serves as the intelligent foundation for your digital transformation, delivering a highly secure, always-on, and IT-simplified network fabric that perfectly aligns with Cisco Software-Defined Access (SD-Access).
Purpose-built to energize your smart building and wireless infrastructure, this model delivers advanced, intelligent Power over Ethernet (providing up to 60W of power per port). This empowers you to effortlessly deploy high-demand IT and OT endpoints—such as ultra-fast Wi-Fi 6/6E access points, 4K PTZ security cameras, and smart LED lighting—completely eliminating the cost and complexity of dedicated electrical wiring. With intelligent features like Perpetual PoE, your critical devices stay powered even during a switch reboot.
What truly sets the C9300-48UN-E apart is its uncompromising mission-critical resiliency combined with smart infrastructure consolidation. At its network core, it ensures zero downtime with modular components and Cisco's exclusive StackPower technology, which intelligently pools power across stack members for unprecedented redundancy. Building on this rock-solid foundation, the switch leverages its embedded x86 architecture to consolidate your network footprint. By natively deploying Cisco ASAc virtual firewalls directly at the access layer, you can secure IoT and user traffic at the source without the expense of purchasing separate physical firewall appliances. Simultaneously, integrated ThousandEyes probes instantly illuminate cloud and application bottlenecks, transforming your access switch into a powerful sensor that guarantees a flawless end-to-end user experience.
