Understanding the C9300L-48P-4X-E=
The Cisco Catalyst C9300L-48P-4X-E= is a Layer 3 stackable switch engineered for environments demanding high Power over Ethernet (PoE) capacity and scalable uplink bandwidth. It features 48x PoE+ Gigabit Ethernet ports and 4x 10G SFP+ uplinks, making it a cornerstone for campuses, healthcare facilities, and smart buildings requiring reliable power and data delivery.
Core Technical Features
- Port Configuration: 48x 10/100/1000BASE-T PoE+ ports + 4x 10G SFP+ uplinks.
- PoE Budget: 740W total, supporting 30W per port (IEEE 802.3bt UPoE) for devices like PTZ cameras, VoIP phones, and access points.
- Stacking: StackWise-160 allows up to 8 switches to operate as a single unit with 160Gbps stacking bandwidth.
- Security: Integrated Cisco DNA Center for zero-trust network access and encrypted traffic analytics.
- Modularity: Includes a network module slot for adding 40G/100G interfaces.
Primary Use Cases
- High-density PoE deployments: Hospitals, schools, or offices deploying hundreds of connected devices.
- Bandwidth-sensitive applications: Supports 10G uplinks for backbone connectivity in data-heavy workflows.
- IoT infrastructure: Manages and powers sensors, digital signage, and wireless controllers seamlessly.
Performance Comparison: C9300L-48P-4X-E= vs. Entry-Level PoE Switches
| Feature | C9300L-48P-4X-E= | Entry-Level PoE Switches |
|---|---|---|
| PoE Budget | 740W | 150-370W |
| Uplink Speed | 4x 10G SFP+ | 1-4x 1G |

| Port Density | 48 PoE+ ports | 24-32 ports |
Key Advantages Over Competing Models
- Future-ready PoE capacity: Delivers UPoE (90W) via optional modules, powering devices like LED lighting or kiosks.
- Simplified management: Cisco DNA Software automates network provisioning and troubleshooting.
- Energy efficiency: EnergyWise technology reduces power consumption by up to 30% compared to older models.
For organizations upgrading to Wi-Fi 6/6E or IoT expansions, this switch’s 8-year hardware warranty ensures long-term reliability.
Cost vs. Value Analysis
While the C9300L-48P-4X-E= has a higher upfront cost, its operational savings from reduced downtime and energy use justify the investment. For certified hardware and licensing, visit the [“C9300L-48P-4X-E=” link to (https://itmall.sale/product-category/cisco/).
Practical Insight
In my experience deploying PoE switches, the C9300L-48P-4X-E= excels in scenarios where power redundancy and uplink speed are non-negotiable. However, its 48-port density might be excessive for small offices. For enterprises scaling IoT or unified communications, this model eliminates the need for external power injectors and streamlines infrastructure.
