C9300L-48UXG-2Q-E Description
The Cisco Catalyst 9300L-48UXG-2Q-E delivers 48 multigigabit UPOE ports—12 ports supporting 10 G/5 G/2.5 G/1 G/100 M and 36 ports supporting 1 G/100 M/10 M—powered by an integrated 1 100 W AC supply that provides a default 675 W PoE budget. Two fixed 40 Gbps QSFP uplinks enable high-speed aggregation to distribution or core. Cisco IOS XE with the Network Essentials license supports wire-speed Layer 2 switching, static/RIP routing, hardware ACLs, and basic QoS. StackWise-320 yields up to 320 Gbps of stacking bandwidth across up to eight switches, presenting the entire stack as a single logical switch. Built-in security features include 802.1X authentication, DHCP Snooping, Dynamic ARP Inspection, and TrustSec. Ideal for PoE-heavy campus and branch deployments—such as IP surveillance, Wi-Fi 6 AP aggregation, and IoT edge—this switch balances multi-gig UPOE power, robust performance, and simplified stacking management.

Key Features
Universal PoE (UPOE)
Supports up to 90 W per port on 12 multi-gig ports and 30 W per port on 36 1 G ports, with a default 675 W PoE budget (expandable to 1025 W/1390 W/1775 W).
StackWise-320 Stacking
Up to 320 Gbps of stacking bandwidth across eight switches, managed as a single logical unit for resiliency and simplified fabric.
40 Gbps Fixed QSFP Uplinks
Two QSFP uplinks deliver ultra-low-latency fiber aggregation without additional modules, simplifying deployment.
Cisco IOS XE Essentials
Provides wire-speed Layer 2 and basic Layer 3 (static/RIP) switching, hardware ACLs, and QoS for essential campus requirements.
Built-In Security
802.1X authentication, DHCP Snooping, Dynamic ARP Inspection, and TrustSec enforce device authentication and mitigate Layer 2 threats.
Simplified Management
Manage via CLI, WebUI, or Cisco DNA Center for centralized policy, automation, and assurance.
Applications Scenarios
High-Density Campus Access
Power 48 UPOE devices (IP cameras, Wi-Fi 6 APs, digital signage) with up to 675 W default PoE; aggregate traffic over two 40 Gbps QSFP uplinks.
Branch Aggregation & IoT Edge
Serve as the access/aggregation point for IoT sensors and UPOE devices; enforce security (802.1X, TrustSec) and QoS at the edge.
Small Data Center Top-of-Rack (ToR)
Provide multi-gig UPOE to servers and service appliances; use 40 Gbps QSFP uplinks for low-latency East-West traffic.
