C9300X-48HXN-E Description
The Cisco Catalyst C9300X-48HXN-E (aka “48HXN UPOE+ mGig switch”) is engineered for high-density, power-hungry campus and branch access. Featuring 8×10 Gbps and 40×5 Gbps multigigabit UPOE+ downlinks, it delivers up to 90 W per port for heavy-duty wireless APs, IP telephony, and IoT endpoints. A 1 Tbps StackWise-1T fabric (1.96 Tbps stacked) ensures non-stop scalability, while hardware-accelerated 100 Gbps IPsec and AES-256 MACsec keep data secure at wire speed. On-switch application hosting—including 16 GB DRAM, 16 GB flash, and a USB 3.0 SSD slot—enables containerized services and analytics at the access layer. The Network Essentials license unlocks fundamental Layer 2/3, programmable QoS, and RESTCONF/NETCONF automation to simplify operations and accelerate digital transformation.
