Practical Deployment Observations
The C9300-24U-1E is indispensable in environments where high-power devices and simplified cabling are priorities. In one deployment, it powered 20x Cisco 9130 APs with 6E support without requiring external injectors. However, its 360W total budget demands careful load balancing—prioritize critical devices and use Cisco Prime or DNA Center to monitor real-time power usage. A common oversight: neglecting to upgrade power supplies when scaling UPOE+ ports. Always pair it with Cisco’s 1100W AC modules for full redundancy in mission-critical setups.
