NXA-PAC-1200W-PI=: Technical Design, Power Ef
Introduction to the Cisco NXA-PAC-1200W-PI= Power Suppl...
Core Features and Design Philosophy
The Cisco Catalyst C9200CX-8P-EDU is a compact, education-focused switch built to power PoE-enabled learning environments like smart classrooms, lecture halls, and campus Wi-Fi deployments. It combines 8x 10/100/1000BASE-T PoE+ ports with 2x 1G SFP uplinks, prioritizing simplicity, durability, and budget-friendly PoE for K-12 and higher education IT teams.
Key differentiators:
- 195W total PoE budget (30W per port), supporting devices like wireless APs, VoIP phones, and interactive displays.
- EDU-specific licensing: Preloaded with Cisco DNA Essentials for Education for simplified network automation and compliance with data privacy laws (e.g., FERPA).
- Fanless, ruggedized chassis: Silent operation for classrooms and resistance to physical wear in high-traffic zones.
Performance and Deployment Scenarios
1. Smart Classroom Infrastructure
Power and connect 20-30 student devices (tablets, laptops) via PoE-driven wireless APs while linking smart boards and AV systems through uplinks.
2. Campus Wi-Fi Backbone
The 195W PoE capacity can support 6-8 Wi-Fi 6 APs, ensuring coverage for auditoriums or outdoor common areas.
3. Administrative Security
Use port security and Cisco TrustSec to isolate staff networks from student traffic, preventing unauthorized access.
Comparison with Similar Cisco EDU Models
| Model | Ports/PoE | Uplinks | Use Case Focus |
|---|---|---|---|
| C9200CX-8P-EDU | 8x PoE+ (195W) | 2x 1G SFP | PoE-heavy classrooms |
| C9200CX-12T-EDU | 12x non-PoE | 2x 1G SFP | Labs, libraries |
| C9200L-8P-4G-E | 8x PoE+ (195W) | 4x 1G SFP | General-purpose PoE |
The 8P-EDU sacrifices port density for targeted PoE optimization and education-centric compliance tools.
Addressing Critical User Questions
Q: Can this switch handle PoE++ (60W) devices like high-end PTZ cameras?
No. It’s limited to PoE+ (30W/port), making it suitable for standard APs and displays. For 60W devices, consider Cisco’s Catalyst 9300 series.
Q: Does the EDU license include lifetime updates?
No. It requires yearly renewal to maintain access to security patches and feature upgrades.
Deployment and Procurement Guidance
- Use StackWise-160 to combine up to 4 units, creating a unified 160 Gbps backbone for larger campuses.

Educator-Centric Evaluation
The C9200CX-8P-EDU is a cost-conscious solution for schools prioritizing immediate PoE needs over scalability. While its 8-port design may seem limited, it aligns with typical classroom device counts, avoiding overprovisioning costs. However, districts planning IoT expansions (e.g., smart lighting, occupancy sensors) should evaluate higher-density models to preempt future upgrades. In budget-strapped environments, this switch delivers essential PoE without superfluous features—a trade-off that often makes sense in education.
