Understanding the C9300LM-48UX-4Y-E=
The Cisco Catalyst C9300LM-48UX-4Y-E= is a 48-port Multi-Gigabit PoE+ switch designed for environments requiring high power delivery, adaptive uplinks, and future-ready scalability. With 48x 1/2.5/5/10GBASE-T PoE+ ports, 4x 40G QSFP28 uplinks, and modular expansion, it addresses bandwidth-intensive use cases like smart buildings, IoT campuses, and immersive collaboration spaces.
Core Technical Features
- Port Configuration: 48x Multi-Gig PoE+ ports (supports UPoE+/90W per port) + 4x 40G QSFP28 uplinks (100G via breakout).
- Power Capacity: 1170W total PoE budget, enabling simultaneous support for Wi-Fi 6E APs, 4K cameras, and digital signage.
- Stacking: StackWise-480 technology aggregates up to 8 switches with 480Gbps stacking bandwidth for unified management.
- Security: Cisco DNA Advantage includes endpoint visibility, encrypted traffic analytics, and zero-trust access controls.
- Modular Expansion: Slot for adding 40G/100G interfaces or application-specific modules (e.g., IoT, SD-WAN).
Ideal Deployment Scenarios
- Smart campuses: Powers and manages thousands of IoT sensors, access points, and AV systems.
- Hybrid workspaces: Delivers 10G connectivity to collaboration tools (e.g., Microsoft Teams Rooms, VR setups).
- Healthcare networks: Supports PoE++ for medical devices and real-time telemetry with QoS prioritization.
Performance Comparison: C9300LM-48UX-4Y-E= vs. Fixed-Port PoE Switches
| Feature | C9300LM-48UX-4Y-E= | Fixed-Port PoE Switches |
|---|---|---|
| PoE Budget | 1170W (90W/port) | ≤ 740W (30W/port) |
| Uplink Speed | 4x 40G/100G | 4x 10G fixed |
| Modular Expansion | Yes | No |
| Stacking Bandwidth | 480Gbps | ≤ 160Gbps |
Key Benefits for IT Architects
- Eliminate power bottlenecks: UPoE+ powers next-gen devices like PTZ cameras or LED walls without external injectors.
- Backbone readiness: 40G/100G uplinks future-proof spine-leaf architectures for 5G and edge computing.
- Simplified operations: Cisco DNA Center automates device provisioning, reducing deployment time by 50% in large-scale networks.
For industries like education or hospitality, its EnergyWise feature cuts power costs by 20-30% through intelligent load management.
Cost vs. Strategic Value
While the C9300LM-48UX-4Y-E= commands a premium, its 10-year lifecycle and modular design defer costly upgrades. For validated hardware and licensing, visit [“C9300LM-48UX-4Y-E=” link to (https://itmall.sale/product-category/cisco/).
Practical Deployment Insight
In smart city projects, I’ve used this switch’s 90W PoE+ to power traffic sensors and edge servers without overloading circuits. However, its 48-port density may exceed small office needs. For enterprises scaling IoT or hybrid collaboration tools, the C9300LM-48UX-4Y-E= is unmatched in balancing power, speed, and adaptability—ideal for teams prioritizing infrastructure longevity over short-term savings.
