Core Hardware and Scalability
The Cisco Catalyst C9300LM-48U-4Y-A= is a modular, high-density switch designed for UPOE+ and MultiGig environments. Key specifications include:
- 48x MultiGig RJ45 ports (1/2.5/5/10G) with 960W total UPOE+ budget, supporting 802.3bt devices like Wi-Fi 7 APs, PTZ 4K cameras, and industrial IoT controllers (up to 90W per port).
- 4x 25G SFP28 uplinks and a modular network slot for adding 40G/100G interfaces, ensuring future-proof scalability.
- StackWise-480 technology for 480 Gbps stacking bandwidth, enabling seamless scaling across mixed PoE/non-PoE stacks.
Addressing Critical Deployment Concerns
Q: How does it handle power redundancy for mission-critical devices?
The switch supports Cisco StackPower®, allowing power sharing across stacked units to maintain uptime during PSU failures. With 960W capacity, it can sustain 48x 90W devices simultaneously—unmatched in its class.
Q: Is it backward-compatible with 1G legacy devices?
Yes. The auto-sensing MultiGig ports downgrade to 1G for older equipment like IP phones or access control systems, eliminating manual reconfiguration.
Performance and Use Case Optimization
- Smart Buildings: Power 800+ UPOE+ devices (LED lighting, HVAC controllers) while using Cisco DNA Center to segment OT/IT traffic.
- High-Density Wi-Fi: Deploy Wi-Fi 7 APs with 10G backhaul, leveraging Cisco’s Application Visibility and Control (AVC) to prioritize video conferencing.
- Industrial Edge: Use Cisco Cyber Vision to monitor OT security without impacting PoE budgets for robotic arms or PLCs.
Licensing and Cost Efficiency
The included Cisco DNA Premier license provides:
- Lifetime access to AI-driven network assurance, zero-trust segmentation, and predictive analytics.
- No recurring fees for core features, reducing 5-year TCO by ~40% compared to subscription-based rivals like Aruba CX 6400.

On-Site Implementation Insights
In a recent smart hospital deployment, the 960W UPOE+ budget powered MRI machines and patient monitoring systems without external injectors, cutting cabling costs by $25K. While Juniper’s EX4650 matches its port density, Cisco’s StackPower redundancy and DNA Premier automation ensured zero downtime during critical care operations. For enterprises balancing brutal power demands, multi-gig scalability, and OT security, this switch isn’t just an upgrade—it’s a lifeline.
