Practical Deployment Insights
The C9300-48P-10A is a workhorse for power-hungry access layers, but its 740W PoE+ budget requires careful load management. In a recent campus rollout, it powered 40x Wi-Fi 6 APs and 8x PTZ cameras without issues—but only after configuring Cisco DNA Center’s Power Monitoring to avoid overloading circuits. One lesson learned: always reserve 10-15% of the PoE budget for redundancy. While its 10G uplinks handle most aggregation needs, consider pairing it with 40G core switches (e.g., C9300-24H) for future scalability. Avoid mixing PoE and non-PoE devices on the same switch if uptime is critical; dedicated power supplies minimize risk during peak loads.
