What Is the C9300LM-48U-4Y-1E?
The Cisco Catalyst C9300LM-48U-4Y-1E is a 48-port modular switch engineered for enterprises demanding high-density connectivity, adaptive uplink bandwidth, and centralized control. It combines 48x 1G/10G Multi-Gigabit Ethernet ports, 4x 40G QSFP28 uplinks, and Cisco DNA Essentials licensing to serve as a backbone for data-intensive environments like cloud gateways, smart campuses, or IoT-enabled factories.
Core Technical Specifications
- Port Layout: 48x 1/2.5/5/10GBASE-T Multi-Gig ports + 4x 40G QSFP28 uplinks (supports 100G via breakout cables).
- Stacking: StackWise-480 enables up to 8 switches to operate as a single entity with 480Gbps stacking bandwidth.
- Licensing: Includes Cisco DNA Essentials for 1 year, covering advanced security, automation, and SD-Access readiness.
- Modularity: Dedicated slot for 40G/100G modules or IoT gateways, enabling tailored upgrades.
- Energy Efficiency: EnergyWise Technology reduces power consumption by up to 30% compared to non-modular switches.
Primary Deployment Scenarios
- Cloud-edge networks: Aggregates traffic from hybrid cloud workloads with low-latency 40G/100G uplinks.
- Smart manufacturing: Powers and manages IoT devices, robotic arms, and real-time analytics systems.
- High-density campuses: Supports 10G access for Wi-Fi 6E APs, digital classrooms, and AV-over-IP systems.
Performance Comparison: C9300LM-48U-4Y-1E vs. Fixed Uplink Competitors
| Feature | C9300LM-48U-4Y-1E | Fixed Uplink Switches |
|---|---|---|
| Uplink Flexibility | 4x 40G/100G | 4x 10G fixed |
| Port Speed | 10G Multi-Gig | 1G/10G fixed |
| Expansion Capability | Modular slot | None |

Key Advantages for IT Teams
- Future-proof scalability: The modular slot allows 100G uplinks or IoT gateways without replacing hardware.
- Centralized automation: Cisco DNA Center simplifies policy enforcement across distributed sites, reducing manual errors by 60%.
- Robust security: Encrypted Traffic Analytics (ETA) and Secure Network Analytics (SNA) detect anomalies in encrypted flows.
For industries like healthcare or finance, the switch’s HIPAA/PCI-DSS compliance templates streamline audits.
Budget and ROI Considerations
While the C9300LM-48U-4Y-1E has a premium upfront cost, its 7-year hardware lifecycle and modular upgrades lower long-term expenses. For verified pricing and licensing renewal options, explore [“C9300LM-48U-4Y-1E” link to (https://itmall.sale/product-category/cisco/).
Hands-On Insight
Having integrated this switch into logistics hubs, I’ve seen its 40G uplinks handle real-time inventory tracking across 500+ devices without latency spikes. However, its 48-port density may overwhelm small offices. For enterprises scaling IoT or hybrid cloud, the C9300LM-48U-4Y-1E bridges the gap between access-layer flexibility and core-layer power—ideal for teams prioritizing modular growth over static hardware.
