​​Introduction to the Cisco Catalyst C9300-24U-A​​

The ​​Cisco Catalyst C9300-24U-A​​ is a high-performance Layer 3 switch designed for environments requiring ​​Universal Power over Ethernet (UPOE)​​ and advanced network automation. Part of the Catalyst 9300 series, it targets enterprises with dense IoT deployments, high-power wireless access points (APs), or devices needing flexible power and data delivery.

​​Key Technical Specifications​​

• ​​24x UPOE+ Ports​​: Delivers up to ​​90W per port​​ (60W default), supporting devices like PTZ cameras, digital signage, and Wi-Fi 6/6E APs.
• ​​4x10G SFP+ Uplinks​​: Enables high-speed stacking via ​​Cisco StackWise-480​​ or backbone connectivity.
• ​​Cisco DNA Advantage Licensing​​: Includes ​​AI-driven network insights​​, ​​SD-Access segmentation​​, and ​​automated threat mitigation​​.
• ​​Scalable Power Budget​​: Offers ​​1,100W total PoE capacity​​ for power-hungry deployments.

​​Addressing Critical User Questions​​

​​Q: How Does UPOE Differ from Standard PoE+?​​

​​UPOE (802.3bt)​​ supports ​​up to 90W per port​​, compared to PoE+ (802.3at), which caps at 30W. This makes the 24U-A ideal for devices like Cisco’s 9100 Wi-Fi 6 APs or building automation systems.

​​Q: Can It Replace Older PoE Switches Like the Catalyst 3850?​​

Yes. The C9300-24U-A provides:

• ​​3x higher PoE capacity​​ than the 3850’s 385W maximum.
• ​​Modern security protocols​​ (MACsec, TrustSec) for encrypted traffic.
• ​​Software-defined management​​ via Cisco DNA Center.

​​Licensing and Future-Proofing​​

The ​​“-A” suffix​​ denotes ​​DNA Advantage licensing​​, which includes:

• ​​Predictive analytics​​ for network health.
• ​​Application visibility​​ and policy enforcement.
• ​​Lifetime hardware warranty​​ with 24/7 Cisco TAC support.
  Upgrading to ​​DNA Premier​​ adds multi-domain integration and extended threat intelligence.

​​Final Evaluation​​

The C9300-24U-A is a powerhouse for organizations prioritizing ​​high-density, high-power connectivity​​. While its upfront cost is higher than entry-level switches, the UPOE flexibility and DNA Advantage tools eliminate the need for external power injectors while future-proofing for IoT expansions. For enterprises modernizing campuses or deploying smart buildings, this switch bridges the gap between legacy PoE limitations and next-gen power demands—making it a strategic investment in scalable infrastructure.
