What Is the Cisco Catalyst C9300-24UXB-E?
The Cisco Catalyst C9300-24UXB-E is a multi-gigabit UPOE++ (Universal Power over Ethernet Plus Plus) switch built for high-density wireless, IoT, and industrial environments. It combines 12x 100M/1G/2.5G/5G/10G Multi-Gigabit RJ45 ports and 12x 1G UPOE++ RJ45 ports, delivering 90W per UPOE++ port alongside 4x 10G SFP+ uplinks. The “B-E” designation includes the Cisco DNA Advantage license, unlocking advanced automation, AI-driven analytics, and zero-trust security.
Key Technical Specifications
- Port Configuration:
- 12x mGig RJ45 ports (supporting 100M to 10G speeds)
- 12x 1G UPOE++ ports (802.3bt, 90W/port, 1080W total PoE budget)
- 4x 10G SFP+ uplinks
- Stacking: StackWise-480 for 480 Gbps stacking bandwidth across 8 switches.
- Power: Dual 1100W AC power supplies (recommended for full PoE++ utilization).
- Software: Cisco IOS XE with DNA Advantage, enabling AI Endpoint Analytics, SD-Access, and Encrypted Traffic Analytics (ETA).

Deployment Lessons Learned
The C9300-24UXB-E is a beast in high-demand environments, but its 1080W PoE++ budget requires meticulous power planning. In a recent smart factory deployment, it powered 10x autonomous robots and 15x Wi-Fi 6E APs—but only after upgrading to dual 1100W PSUs and configuring Cisco EnergyWise for dynamic load balancing. A common oversight: underestimating the heat generated by UPOE++ ports. Ensure adequate cooling and avoid overloading ports in confined spaces. For future-proofing, pair it with 40G core switches (e.g., C9300-24H) to prevent uplink congestion in data-heavy setups. Always validate firmware compatibility with UPOE++ devices to avoid negotiation failures.
