Overview of the Cisco C9300L-48PF-4X-E
The Cisco C9300L-48PF-4X-E is a high-performance Layer 3 switch optimized for environments demanding both high Power over Ethernet (PoE) capacity and 10G uplink scalability. Part of the Catalyst 9300L series, it caters to enterprise networks requiring robust power delivery for IoT, unified communications, and advanced security.
Core Technical Specifications
- Port Configuration: 48 x Gigabit Ethernet PoE+ ports, 4 x 10G SFP+ uplinks.
- Power Budget: 740W total PoE capacity, supporting up to 30W per port (PoE+) for devices like Wi-Fi 6 APs, IP cameras, and VoIP systems.
- Performance: 220 Gbps switching capacity with Cisco DNA Advantage licensing, enabling features like application visibility, encrypted traffic analytics, and automated QoS.
- Scalability: Supports StackWise®-160 for stacking up to 8 switches, creating a unified management domain with 160 Gbps bandwidth.
Key Use Cases and User Concerns
Q: Can the C9300L-48PF-4X-E handle high-density PoE deployments?
Absolutely. With 740W of PoE power, it efficiently supports power-hungry devices like PTZ security cameras, digital signage, and next-gen wireless access points.
Q: Are the 10G uplinks sufficient for backbone connectivity?
The four built-in 10G SFP+ ports provide ample bandwidth for aggregating traffic from multiple switches or connecting to core networks, ensuring minimal bottlenecks in data-heavy environments.
C9300L-48PF-4X-E vs. Similar Models
Compared to the C9300L-48PF-4G-1E, this model replaces the 1G uplinks and expansion slot with four native 10G SFP+ ports, eliminating the need for add-on modules. The “E” suffix denotes pre-installed DNA Essentials licensing, whereas the “4X-E” variant often includes DNA Advantage for advanced features.
Licensing and Deployment Tips
The switch comes with Cisco DNA Essentials by default, covering basic automation and security. Upgrading to DNA Advantage unlocks AI-driven network insights, SD-Access integration, and end-to-end segmentation.

Practical Insights from Deployment Experience
Having configured similar switches for campus networks, the C9300L-48PF-4X-E shines in environments where PoE density and uplink speed are non-negotiable. While its lack of 40G uplinks limits use in hyperscale data centers, it’s a cost-effective workhorse for enterprises balancing IoT growth with future-ready infrastructure. Always audit PoE requirements beforehand—overestimating power needs can lead to underutilized capacity, while underestimating risks overloads.
