C9300X-48HXN-A Description
The Cisco Catalyst C9300X-48HXN-A, known as the “48HXN Advantage multigigabit switch,” delivers converged access and power consolidation for today’s demanding campus and branch-edge environments. With 8×10 Gbps and 40×5 Gbps UPOE+ ports (up to 90 W per port), it powers high-density Wi-Fi 6/6E access points, IP telephony, security cameras, and IoT devices over a single cable. A 1 Tbps StackWise-1T fabric (1.96 Tbps in an eight-member stack) provides seamless scaling, while 100 Gbps hardware IPsec and AES-256 MACsec ensure data-in-transit protection. The on-switch application platform features a quad-core x86 CPU, 16 GB of DRAM, 16 GB flash, and a USB 3.0 SSD slot, supporting containerized services and analytics at the access layer. The Network Advantage license unlocks advanced routing, MPLS, segment routing, and enhanced QoS for mission-critical networks.
