What Is the C9300L-48PF-4G-E=?
The Cisco Catalyst C9300L-48PF-4G-E= is a 48-port PoE+ (Power over Ethernet) switch designed for demanding environments requiring simultaneous high-speed data and power delivery. With 48x Gigabit Ethernet ports (supporting PoE+) and 4x 10G SFP+ uplinks, it serves as a backbone for modern IoT deployments, enterprise campuses, and unified communication systems.
Critical Technical Specifications
- Port Layout: 48x 10/100/1000BASE-T PoE+ ports + 4x 10G SFP+ uplinks.
- PoE+ Budget: 740W total, delivering up to 30W per port (IEEE 802.3at) for devices like IP cameras, wireless APs, and VoIP systems.
- Stacking: StackWise-160 supports up to 8 switches in a stack with 160Gbps bandwidth.
- Security: Built-in Cisco DNA Assurance and MACsec encryption for end-to-end traffic protection.
- Expandability: Modular network slot for adding 40G/100G interfaces or PoE+ expansion modules.
Ideal Use Cases
- High-density workspaces: Offices or campuses with hundreds of connected devices.
- Healthcare or education: Supports HIPAA-compliant networks or digital classrooms with PoE-powered displays.
- Smart buildings: Powers and manages IoT sensors, access control systems, and lighting.
Performance Comparison: C9300L-48PF-4G-E= vs. Basic PoE Switches
| Feature | C9300L-48PF-4G-E= | Basic PoE Switches |
|---|---|---|
| PoE Budget | 740W | 250-400W |
| Uplink Speed | 4x 10G SFP+ | 1-2x 1G |
| Stacking Capability | Yes (160Gbps) | Limited or none |
| Port Density | 48 PoE+ ports | 24-32 ports |
Why This Model Stands Out
- Scalable power delivery: The 740W total PoE budget eliminates the need for external power injectors, even in device-heavy setups.
- Future-ready uplinks: 10G SFP+ ports ensure backbone bandwidth doesn’t bottleneck during peak traffic.
- Centralized management: Cisco DNA Center simplifies network automation, reducing configuration time by up to 70%.
For organizations planning Wi-Fi 6/6E rollouts, this switch’s PoE+ capacity ensures seamless AP powering without upgrades.
Cost Considerations
While the C9300L-48PF-4G-E= has a premium price tag, its total cost savings from reduced hardware sprawl and energy efficiency (via Cisco EnergyWise) offset initial investments.

Expert Perspective
Having integrated this switch into retail and campus networks, I’ve found its PoE+ headroom invaluable for avoiding power over-subscription. However, smaller deployments (e.g., under 20 devices) may not fully utilize its capacity. For enterprises scaling IoT or hybrid work models, though, the C9300L-48PF-4G-E= is a strategic long-term solution that minimizes infrastructure churn.
