The Cisco Catalyst C9300L-24UXG-4X-A is a versatile switch designed to address the growing demand for high-speed connectivity and power delivery in mid-sized networks. Part of the Catalyst 9300L Series, it combines multi-gigabit Ethernet, Universal PoE+, and advanced security features at a scalable price point. Leveraging Cisco.com’s technical specifications and ​​itmall.sale​​’s sourcing data, we analyze its role in modernizing hybrid work and IoT environments.

Core Specifications and Hardware Capabilities

The ​​C9300L-24UXG-4X-A​​ is engineered with:

• ​​24x Multi-Gigabit Ethernet ports​​ (1/2.5/5/10G) with ​​Universal PoE+ (UPOE+)​​ support, delivering up to 90W per port.
• ​​4x 10G SFP+ uplinks​​ for high-speed aggregation or backbone connectivity.
• ​​740W total PoE budget​​, enabling simultaneous power delivery to devices like ​​Wi-Fi 6E APs​​, ​​PTZ cameras​​, and ​​building automation controllers​​.
• ​​Cisco IOS XE​​ with ​​DNA Advantage​​ for software-defined access (SD-Access), AI-driven analytics, and encrypted traffic inspection.
• ​​StackWise-80​​ support, allowing up to four switches to operate as a unified system with an 80 Gbps backplane.

Key Differentiators for Modern Networks

​​1. Multi-Gig and PoE+ Synergy​​

The switch’s ​​Multi-Gig ports​​ eliminate bottlenecks for high-throughput devices like Wi-Fi 6E APs, while ​​UPOE+​​ powers them without external injectors. This dual capability simplifies cabling and reduces infrastructure sprawl.

​​2. Scalable Security Posture​​

Integrated ​​Cisco TrustSec​​ enforces role-based access, and ​​Encrypted Traffic Analytics (ETA)​​ identifies malware in encrypted flows without decryption overhead—critical for compliance-driven industries.

​​3. Cost-Effective Stacking​​

​​StackWise-80​​ enables seamless expansion for growing networks, ensuring consistent policy management and redundancy across up to four switches.

Ideal Deployment Scenarios

• ​​Hybrid Workspaces​​: Supports high-density APs, video conferencing systems, and occupancy sensors with Multi-Gig speeds and PoE+.
• ​​Healthcare Networks​​: Powers and connects medical IoT devices (e.g., smart beds, infusion pumps) while ensuring HIPAA-compliant segmentation.
• ​​Retail Innovation Hubs​​: Drives interactive kiosks, AR/VR displays, and inventory robots with scalable uplinks and power.

Addressing Critical Buyer Questions

​​Can the 740W Budget Fully Power 24 Multi-Gig Devices?​​

No. While ​​UPOE+​​ supports 90W per port, the total budget allows ~30W per port across all 24 devices. Prioritize high-wattage allocations for critical gear (e.g., ​​Wi-Fi 6E APs​​) and limit others (e.g., ​​IP phones​​) to 15W.

​​Does DNA Advantage Justify the Cost?​​

Yes. Beyond basic automation, DNA Advantage unlocks ​​SD-Access​​ for microsegmentation, ​​Cisco ThousandEyes​​ for WAN insights, and ​​AI Endpoint Analytics​​—essential for proactive network management.

​​Is Redundancy Supported?​​

Yes. Optional ​​715W AC power supplies​​ (hot-swappable) and ​​StackWise-80​​ ensure uptime during hardware failures.

Practical Deployment Insights

Deploying this switch in a university campus revealed its ​​strength in simplifying IoT integrations​​—Wi-Fi 6E APs and digital signage ran seamlessly without power or speed compromises. However, the 740W ceiling demands disciplined power mapping; overcommitting ports led to unexpected throttling during peak usage. While pricier than non-PoE models, the ​​long-term ROI from reduced cabling and centralized management​​ justifies the investment. For mid-sized networks eyeing future-ready scalability, the C9300L-24UXG-4X-A strikes a rare balance between innovation and pragmatism.
