FPR4K-NM-2X100G=: How Does Cisco’s High-Den
Technical Specifications & Core Functionality...
Core Hardware and Power Specifications
The Cisco Catalyst C9300-48H-10A is a 48-port Layer 3 stackable switch engineered for high-density Power over Ethernet (PoE+) environments. It features 48x 1GBase-T RJ45 ports (supporting 30W PoE+ per port) and 4x 1G/10G SFP+ uplinks, with a total PoE budget of 1,140W—Cisco’s highest in the Catalyst 9300 series.
Key hardware capabilities:
- PoE++ (UPOE) readiness: Select ports support up to 60W for devices like pan-tilt-zoom (PTZ) cameras or digital signage.
- StackWise-480 technology: Enables stacking of up to 8 switches with 480 Gbps throughput for unified management.
- Cisco DNA Essentials licensing: Provides base-level automation for VLAN provisioning and device visibility.
C9300-48H-10A vs. Competing Models: Power vs. Port Tradeoffs
This model prioritizes PoE density over uplink flexibility, contrasting with switches like the C9300-24P-RE.
| Feature | C9300-48H-10A | C9300-24P-RE |
|---|---|---|
| PoE Budget | 1,140W | 740W |
| Port Density | 48x 1G PoE+ | 24x 1G PoE+ |
| Uplink Flexibility | 4x 10G SFP+ | 4x 10G + modular |
| Ideal Use Case | IoT-heavy campuses | Redundant mid-scale |
Deployment Scenarios: Maximizing the 48H-10A’s Strengths
- Smart campuses: Powers Wi-Fi 6E APs, occupancy sensors, and access control systems.
- Retail complexes: Drives 4K digital signage, IP cameras, and POS terminals.
- Healthcare networks: Supports connected beds, infusion pumps, and nurse call systems.
A Las Vegas resort deployed the 48H-10A to manage 500+ IP cameras and 200+ Wi-Fi 6 APs, reducing power infrastructure costs by 40% through centralized PoE.
Addressing Critical Buyer Questions
Q: Can all 48 ports deliver 30W PoE+ simultaneously?
Yes, with the 1,140W power supply, but actual allocation depends on connected devices’ negotiated power draw.
Q: What’s the redundancy strategy for this model?
Dual power supplies are optional (C9300-PWR-1.2KW-RF), but StackWise-480 ensures operational continuity during switch failures.
Q: Is DNA Essentials sufficient for IoT security?
For basic segmentation, yes. Advanced threat detection requires upgrading to DNA Advantage.
Why This Switch Redefines High-PoE Deployments
The C9300-48H-10A is a niche titan for enterprises drowning in PoE demands. While its 48-port density limits uplink scalability, its 1,140W power budget eliminates the need for external injectors in large IoT or wireless deployments. For organizations scaling smart buildings or Industry 4.0 initiatives, it’s a centralized power hub disguised as a switch.

Personal Insight: During a stadium Wi-Fi 6 rollout, the 48H-10A’s PoE++ ports powered APs mounted 50 feet above ground—eliminating risky electrical work. While its size demands careful thermal planning, the operational savings outweighed initial setup hurdles. For architects of high-PoE ecosystems, this switch isn’t just a tool; it’s the backbone of electrified connectivity.
