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.
