C9300L-24UXG-4X-M: How Does Cisco’s Switch Solve High-Density Multi-Gigabit and UPOE+ Demands for Modern Enterprises?

​​Core Capabilities and Design Focus​​

The ​​Cisco Catalyst 9300L-24UXG-4X-M​​ is a ​​24-port multi-gigabit UPOE+ switch​​ designed for enterprises requiring ​​simultaneous high-power delivery​​, ​​multi-gigabit access​​, and ​​scalable 100G uplinks​​. It provides ​​90W UPOE+ per port​​ (total ​​1,920W PoE budget​​) to support devices like ​​Wi-Fi 7 access points​​, ​​AI-powered surveillance systems​​, and ​​industrial IoT controllers​​, while its ​​four QSFP28 uplink slots​​ enable native 40G/100G connectivity or breakout configurations (e.g., 4x25G). Built on ​​Cisco StackWise-320​​, it allows stacking of up to eight switches with ​​320 Gbps stacking bandwidth​​, ideal for unified management in large campuses or data centers.

Integration with ​​Cisco DNA Center​​ enables policy automation and threat response, while ​​IOS XE Software​​ ensures compatibility with ​​SD-Access​​ and ​​Application Hosting​​ for edge compute workloads.

​​Technical Specifications and Performance​​

• ​​Port Configuration​​: 24 x 5/10GBase-T UPOE+ ports + 4 x QSFP28 uplinks (40G/100G native or 4x25G/10G breakout).
• ​​Switching Capacity​​: 1.44 Tbps (non-blocking).
• ​​Forwarding Rate​​: 1.08 Bpps (bidirectional).
• ​​Power Supply​​: 2200W AC (hot-swappable, N+1 redundancy).
• ​​Security​​: ​​MACsec-256 encryption​​, ​​Cisco TrustSec​​ microsegmentation, and ​​Encrypted Traffic Analytics (ETA)​​ for encrypted threat detection.

The switch runs ​​Cisco IOS XE 17.12+​​, supporting ​​containerized applications​​ (e.g., localized analytics) directly on the device via ​​Application Hosting​​.

​​Key Deployment Scenarios​​

• ​​Smart campuses​​: Powers ​​digital twin sensors​​, ​​collaboration hubs​​, and ​​smart lighting​​ with guaranteed 90W UPOE+.
• ​​Manufacturing​​: Connects ​​autonomous robots​​, ​​AR/VR maintenance tools​​, and ​​PLC systems​​ with <1ms latency.
• ​​Healthcare​​: Ensures ​​zero downtime​​ for ​​connected MRI machines​​ and ​​patient monitoring systems​​ in critical environments.

The ​​QSFP28 uplinks​​ enable seamless migration to 100G spine-leaf topologies or metro DWDM links, eliminating costly hardware replacements.

​​Licensing and Software Integration​​

• ​​Cisco DNA Essentials​​: Basic automation, monitoring, and device onboarding.
• ​​Cisco DNA Advantage​​: Unlocks ​​AI Endpoint Analytics​​, ​​Predictive NetOps​​, and ​​SD-WAN integration​​ for end-to-end policy enforcement.

No additional licenses are required for UPOE+ or StackWise-320 functionality.

​​Competitive Advantages​​

• ​​Dedicated 90W Per Port​​: Competing switches often share power pools, risking outages during peak demand.
• ​​Breakout Flexibility​​: Rival models (e.g., Juniper QFX5120-48YM) lack native 25G/10G breakout support, forcing expensive mid-life upgrades.
• ​​Edge Compute Ready​​: Rare in competitors, ​​Application Hosting​​ reduces latency by processing IoT data locally.

​​Sourcing and Compatibility​​

For verified hardware and Cisco support, “C9300L-24UXG-4X-M” is available here. Use ​​QSFP-100G-SR4​​ (100m) or ​​QSFP-40G-LR4​​ (10km) transceivers based on distance requirements.

​​Why This Model Stands Out​​

The C9300L-24UXG-4X-M redefines edge networking by merging ​​power density​​, ​​multi-gig readiness​​, and ​​100G scalability​​ into a single chassis. While its upfront cost is enterprise-tier, the long-term ROI emerges from eliminating oversubscription risks, streamlining IoT/OT convergence, and future-proofing infrastructure. For IT leaders bridging the gap between today’s needs and tomorrow’s demands, this switch isn’t just hardware—it’s a strategic accelerator.
