C9300L-48UXG-4X-E Description
The Cisco Catalyst 9300L-48UXG-4X-E delivers twelve multi-gig UPOE ports (10 G/5 G/2.5 G/1 G/100 M) alongside thirty-six 1 G/100 M/10 M UPOE copper ports, powered by an integrated 1100 W AC supply that provides a default 675 W PoE budget. Four fixed 10 Gbps SFP+ uplinks enable fiber connectivity to distribution or core switches. Running Cisco IOS XE with the Network Essentials license, this switch supports wire-speed Layer 2 switching, static and RIP routing, hardware-based ACLs, and basic QoS. StackWise-320 technology provides up to 320 Gbps of stacking bandwidth across eight switches, presenting the stack as a single logical device for simplified management. Built-in security features include 802.1X authentication, DHCP Snooping, Dynamic ARP Inspection, and TrustSec, enforcing access control and mitigating Layer 2 threats. Ideal for PoE-heavy campus and branch deployments—such as IP surveillance, Wi-Fi 6 AP aggregation, and IoT edge—this model balances multi-gig UPOE power, robust performance, and resilient stacking.

Key Features
Compact 10 Gbps SFP+ Uplinks
Four fixed SFP+ ports provide 10 Gbps uplink throughput without needing modular slots, reducing cost and simplifying deployments.
Multi-Gig UPOE
Twelve multi-gig UPOE ports negotiate speeds from 100 Mbps up to 10 Gbps and supply up to 90 W each, ideal for Wi-Fi 6 APs and AI/ML-enabled IoT devices.
Network Essentials License
Supports wire-speed Layer 2 switching, static/RIP routing, basic hardware ACLs, and QoS—meeting fundamental campus requirements without extra licensing.
StackWise-320 Resiliency
Up to 320 Gbps stacking bandwidth across eight switches for unified control plane and high availability; hot-swap stacking modules for easy maintenance.
Built-In Security
802.1X authentication, DHCP Snooping, Dynamic ARP Inspection, and TrustSec protect against unauthorized devices and mitigate Layer 2 threats at the edge.
Cisco IOS XE Programmability
Supports RESTCONF, NETCONF, gNMI model-driven telemetry, on-box Python scripting, and YANG-based automation—enabling integration with DevOps pipelines.
Applications Scenarios
Campus Distribution Closets
Use this model in mid-tier distribution closets to aggregate multiple access switches—leveraging 4 × 10 Gbps uplinks—while powering high-density UPOE devices like Wi-Fi 6 APs and IoT sensors.
Branch Office PoE Hub
Serve as the central PoE hub in a branch location, connecting a mix of IP phones, security cameras, and wireless APs. Four 10 Gbps SFP+ uplinks link back to the headquarters WAN router for resilient connectivity.
Edge Data Center Leaf Switch
Deploy as a leaf switch at edge data centers where server racks require multi-gig connectivity. Four 10 Gbps uplinks feed into core spine switches, and UPOE powers remote management appliances or specialized network devices.
