What Is the Cisco C9300-48U-A?

The ​​C9300-48U-A​​ is a ​​48-port 1GBase-T Universal Power over Ethernet (UPOE) switch​​ from Cisco’s Catalyst 9300 Series. Built for environments demanding ​​high-power device support​​, it combines ​​advanced Layer 3 features​​, ​​scalability​​, and ​​enterprise-grade security​​ to handle IoT, wireless, and converged network deployments.

Core Technical Specifications

• ​​Port Configuration​​: ​​48 x 1G RJ45 UPOE+ ports​​ (supports ​​90W per port​​) + ​​4 x 1G/10G SFP+ uplinks​​.
• ​​UPOE+​​: Delivers ​​up to 90W per port​​ for power-hungry devices like ​​PTZ cameras, high-end APs, and digital signage​​.
• ​​Performance​​: ​​176 Gbps switching capacity​​ with ​​StackWise-320​​ for multi-swinegration.
• ​​Security​​: ​​Cisco TrustSec, MACsec encryption, and Secure Boot​​ for end-to-end network hardening.

Key Advantages Over Standard PoE Switches

• ​​UPOE+ Flexibility​​: Powers ​​Cisco’s highest-wattage devices​​ without external injectors, reducing cabling complexity.
• ​​Energy Efficiency​​: ​​IEEE 802.3bt compliance​​ optimizes power allocation based on device needs, cutting energy waste by 30%.
• ​​Future-Proofing​​: Supports ​​Cisco DNA Software​​ for automated network management and ​​SD-Access integration​​.

Ideal Deployment Scenarios

• ​​Smart Buildings​​: Powers ​​4K IP cameras, access control systems, and HVAC controllers​​ on a single infrastructure.
• ​​Wireless Networks​​: Supports ​​Wi-Fi 6/6E APs​​ with uninterrupted power and QoS prioritization.
• ​​Retail Environments​​: Drives ​​digital kiosks, LED displays, and POS systems​​ without overloading circuits.

How Does It Compare to the C9300-48T-A?

While the ​​48T-A​​ offers ​​standard PoE+ (30W per port)​​, the ​​48U-A​​ excels in ​​high-power scenarios​​ with ​​UPOE+​​. The 48U-A also includes ​​enhanced buffering​​ for traffic-heavy IoT networks, making it 20-35% more capable in mixed-device environments. For cost-sensitive projects without UPOE needs, the 48T-A remains viable.
