On-the-Ground Deployment Insights
The C9300-24UB-A is a powerhouse for future-proofing high-PoE networks, but its 720W power budget demands meticulous planning. In a recent warehouse deployment, it efficiently powered 15x 802.11ax APs and 10x robotic arms—but only after upgrading to dual 1100W PSUs. One lesson learned: DNA Advantage’s AI Endpoint Analytics is invaluable for preemptively identifying power-hungry devices causing instability. Always validate power supply redundancy before scaling UPOE++ ports beyond 50% capacity. If budget permits, pair it with 40G core switches (e.g., C9300-24H) to avoid uplink bottlenecks in data-heavy environments.
