Core Hardware and Port Configuration

The ​​Cisco Catalyst 9300L-48UXG-4X-E=​​ is a ​​48-port multi-Gigabit Layer 3 switch​​ blending ​​UPOE+ (90W per port)​​ and ​​multi-Gig (2.5G/5G) Ethernet support​​. It features ​​48x 1G/2.5G/5GBase-T UPOE+ ports​​ and ​​4x 10G SFP+ uplinks​​, powered by a ​​715W AC power supply​​. Running on ​​Cisco IOS XE​​, it supports advanced automation, security, and ​​StackWise-320​​ for scalable deployments.

High-Power PoE and Multi-Gig Performance

• ​​UPOE+ (IEEE 802.3bt)​​: Delivers ​​90W per port​​ to devices like ​​Wi-Fi 6E access points​​, ​​PTZ cameras​​, and ​​industrial IoT controllers​​.
• ​​Multi-Gig Ethernet​​: Supports ​​1G/2.5G/5G speeds​​ on all RJ45 ports, ensuring backward compatibility while preparing for future bandwidth demands.

Scalability and Stacking

• ​​StackWise-320​​: Combine up to 8 switches into a single stack with ​​640 Gbps stacking bandwidth​​, simplifying management in large-scale deployments.
• ​​Switching Capacity​​: 116 Gbps total throughput handles concurrent high-speed data and power delivery without bottlenecks.

Security and Network Segmentation

• ​​Cisco TrustSec®​​: Enables ​​micro-segmentation​​ to isolate IoT devices and enforce role-based access policies.
• ​​Encrypted Traffic Analytics (ETA)​​: Identifies threats in encrypted traffic without decryption, reducing compliance risks.

Target Use Cases

Ideal for ​​high-density wireless deployments​​ (e.g., stadiums, campuses) or ​​smart factories​​ requiring both multi-Gig speeds and UPOE+. Its ​​flexible power budgeting​​ ensures critical devices like safety sensors or AV systems remain prioritized during outages.

Licensing and Support

• ​​Cisco DNA Essentials​​: Included with the switch, offering basic automation and network visibility tools.
• ​​Upgrade to DNA Advantage​​: Unlocks ​​SD-Access​​, ​​AI-driven insights​​, and ​​Cisco ThousandEyes​​ for end-to-end network monitoring.
• ​​Lifetime Hardware Warranty​​: Includes 24/7 TAC support and replacement for hardware failures.

Cost vs. Future-Proofing

Though pricier than standard PoE switches, the ​​C9300L-48UXG-4X-E=​​ eliminates the need for separate multi-Gig adapters or midspans. Its ​​10G uplinks​​ and ​​5GBase-T readiness​​ ensure compatibility with emerging Wi-Fi 7 and industrial IoT standards.
