What Is the C9300-24UX-1A Switch? Multi-Gig Flexibility, PoE++, and DNA Advantage Licensing

Overview of the C9300-24UX-1A

The ​​Cisco Catalyst C9300-24UX-1A​​ is a high-performance, Multi-Gigabit switch engineered for environments requiring adaptive connectivity and extreme Power over Ethernet (PoE) capabilities. Designed for enterprise edge and IoT-heavy deployments, this model balances future-ready speeds with advanced software-defined networking (SDN) features.

Hardware and Performance Highlights

• ​​Port Configuration​​:
  • 24x ​​Multi-Gigabit RJ45 ports​​ (100M/1G/2.5G/5G/10G auto-negotiating) + 4x10G SFP+ uplinks.
  • ​​PoE++ Support​​: Delivers ​​740W total power​​ with ​​up to 90W per port​​ (IEEE 802.3bt), ideal for ​​Wi-Fi 6E APs​​, industrial IoT, and AV systems.
• ​​Stacking​​: Uses ​​Cisco StackWise-480​​ for unified management of up to 8 switches, with 480Gbps per-stack bandwidth.
• ​​Throughput​​: ​​1.6 Tbps non-blocking switching capacity​​ ensures low latency for real-time applications like video streaming and UCaaS.

Software and Licensing Insights

• ​​Cisco DNA Advantage​​: Pre-bundled licensing unlocks ​​SD-Access segmentation​​, ​​Encrypted Traffic Analytics (ETA)​​, and AI-driven network assurance.
• ​​Subscription Model​​: Includes 3 years of software updates and Cisco TAC support, with options to renew or upgrade to DNA Premier.

Key Use Cases

• ​​High-Density Wireless​​: Powers and connects ​​ultra-dense Wi-Fi 6/6E deployments​​ in stadiums, conference centers, or campuses.
• ​​Smart Office Infrastructure​​: Supports hybrid work tools like video conferencing systems, digital whiteboards, and IP phones.
• ​​Industrial IoT​​: Manages high-power sensors, robotics, and automation equipment in manufacturing or logistics environments.

Addressing Critical User Questions

​​Q: How does the 24UX-1A differ from the 24U-10E model?​​
A: The 24UX-1A adds ​​DNA Advantage licensing by default​​ and supports ​​10G speeds on all Multi-Gig ports​​, whereas the 24U-10E caps Multi-Gig ports at 5G without bundled advanced licensing.

​​Q: Can the switch handle legacy PoE devices?​​
A: Yes—backward compatibility with ​​802.3af/at​​ ensures support for older IP cameras, phones, and APs.

​​Q: Is the DNA Advantage license transferable?​​
A: No—licensing is ​​tied to the device serial number​​, making it non-transferable between switches.

Procurement and Compatibility

The C9300-24UX-1A is available through Cisco’s authorized partners. For verified pricing and licensing compliance, ​​“C9300-24UX-1A” can be purchased via itmall.sale​​.

Final Analysis

The C9300-24UX-1A is a powerhouse for organizations bridging the gap between current and future connectivity demands. Its combination of Multi-Gig adaptability and PoE++ readiness eliminates the need for mid-lifecycle hardware upgrades, particularly in wireless or IoT-centric deployments. While the upfront cost is significant, the baked-in DNA Advantage licensing reduces long-term operational overhead—a critical factor for teams prioritizing automation and security. For enterprises building agile, high-performance networks, this switch is less of an expense and more of a strategic asset.
