Technical Overview of the C9300LM-24U-4Y-E
The Cisco Catalyst C9300LM-24U-4Y-E is a 24-port Universal PoE (UPOE) Layer 3 switch designed for high-power, high-density IoT and wireless deployments. It features 24 x 1G Multi-Gigabit Ethernet ports with UPOE+ support (up to 90W per port) and 4 x 25G SFP28 uplinks (4Y) for high-speed aggregation. Bundled with Cisco DNA Essentials licensing (E), it provides foundational automation, security, and analytics tools, making it a fit for enterprises balancing power demands with scalability.
Key Features and Competitive Advantages
- UPOE+ Powerhouse: Delivers 1.8kW total PoE budget, supporting energy-hungry devices like PTZ cameras, digital signage, and Wi-Fi 6E access points without external power sources.
- 25G Future-Proofing: The 4x25G uplinks enable seamless integration into spine-leaf architectures or high-bandwidth data center edges.
- DNA Essentials Licensing: Includes Cisco SD-Access for policy-based automation and Encrypted Traffic Analytics (ETA) for identifying encrypted threats.
- StackWise-480: Supports stacking with 480Gbps bandwidth, enabling up to 8 switches to operate as a single entity for simplified management.
Optimal Use Scenarios
- Smart City Infrastructure: Powers IoT networks for traffic control, environmental sensors, and public Wi-Fi hotspots.
- High-Density Wireless: Backhauls Wi-Fi 6/6E deployments in stadiums, conference centers, or campuses.
- Healthcare Facilities: Connects medical devices, IP intercoms, and patient monitoring systems with redundant power and low latency.

Addressing Critical User Questions
Q: Can this switch support legacy 10G SFP+ modules?
A: Yes—the 25G SFP28 ports are backward-compatible with 10G/1G optics for gradual upgrades.
Q: Is the DNA Essentials license upgradable to DNA Advantage?
A: Yes, but it requires a license migration fee and unlocks features like SD-WAN and Cisco Stealthwatch.
Q: What redundancy features are included?
A: Supports N+1 power supply redundancy (optional) and StackWise-480 for hitless failover during stack member outages.
Q: How does UPOE+ differ from PoE++?
A: UPOE+ is Cisco’s proprietary standard offering 90W per port, while PoE++ (802.3bt) caps at 71W. Ensure device compatibility before deployment.
Practical Insight
The C9300LM-24U-4Y-E shines in environments where power delivery and high-speed uplinks are non-negotiable. Its 1.8kW PoE budget eliminates the clutter of midspans, while 25G uplinks ensure readiness for bandwidth spikes. However, organizations must weigh the premium cost of UPOE+ against actual device requirements—deploying this in low-power scenarios wastes its potential. For venues like airports or hospitals, where uptime and device density are critical, this switch is a strategic long-term investment. In contrast, standard PoE+ models suffice for basic office setups, making the 24U-4Y-E a niche but powerful tool for specific challenges.
