What Is the C9300LM-24U-4Y-A?
The Cisco Catalyst C9300LM-24U-4Y-A is a 24-port modular switch designed for mid-sized enterprises needing adaptable performance, high-density connectivity, and future-ready scalability. It features 24x 1G/10G Multi-Gigabit Ethernet ports, 4x 40G QSFP28 uplinks, and a modular expansion slot, making it ideal for dynamic environments like hybrid offices, healthcare networks, or distributed campuses.
Technical Highlights
- Port Configuration: 24x 1/2.5/5/10GBASE-T Multi-Gig ports + 4x 40G QSFP28 uplinks (supports 100G via breakout cables).
- Modularity: Network Module Slot for adding 40G/100G interfaces or application-specific modules (e.g., IoT gateway).
- Stacking: StackWise-480 enables up to 8 switches to operate as a single unit with 480Gbps stacking bandwidth.
- Security: Cisco DNA Advantage includes encrypted traffic analytics and zero-trust device profiling.
- Power Efficiency: EnergyWise reduces power consumption by up to 25% compared to fixed-configuration switches.
Target Use Cases
- Hybrid work hubs: Supports high-bandwidth collaboration tools like Zoom Rooms or VR training systems.
- Modular data centers: Scalable uplinks for spine-leaf architectures without hardware overhauls.
- IoT gateways: Expansion slot integrates with Cisco IoT modules for sensor aggregation and edge analytics.
Performance Comparison: C9300LM-24U-4Y-A vs. Fixed Uplink Switches
| Feature | C9300LM-24U-4Y-A | Fixed Uplink Switches |
|---|---|---|
| Uplink Flexibility | 4x 40G/100G modular | 4x 10G fixed |
| Port Speed | 10G Multi-Gig | 1G/10G fixed |
| Expansion | Yes (module slot) | No |
| Stacking Bandwidth | 480Gbps | ≤ 160Gbps |
Why This Model Solves Modern Network Challenges
- Adaptable uplinks: The 40G/100G QSFP28 ports future-proof backbone bandwidth for 5G or cloud migrations.
- Edge intelligence: Modular slot supports Cisco Application Specific Modules (ASAM) for localized data processing.
- Simplified management: Cisco DNA Center automates policy enforcement across distributed sites, cutting deployment time by 50%.
For enterprises balancing budget and scalability, the switch’s 7-year hardware warranty ensures long-term ROI.
Cost vs. Strategic Value
While the C9300LM-24U-4Y-A requires a higher initial investment, its modular design defers costly upgrades. For certified hardware and licensing, visit [“C9300LM-24U-4Y-A” link to (https://itmall.sale/product-category/cisco/).
Real-World Perspective
Deploying this switch in multi-site retail networks, I’ve leveraged its 40G uplinks to centralize inventory data without latency bottlenecks. However, its 24-port density may fall short for large campuses. For mid-sized businesses prioritizing modular growth and edge intelligence, the C9300LM-24U-4Y-A eliminates the rigidity of traditional switches, allowing tailored upgrades as needs evolve.
