UCS-CPU-I6354C=: High-Density Intel Xeon Proc
Technical Specifications and Microarchitecture...
Core Specifications and Target Applications
The Cisco Catalyst C9200L-48PXG-4XA++ is a 48-port multigigabit PoE+ switch engineered for high-density, power-hungry environments requiring advanced automation and security. It features 48x RJ45 ports (1/2.5/5G speeds), 4x10G SFP+ uplinks, and Cisco DNA Advantage with Essentials (A++) licensing. Designed for scalability, it supports StackWise Virtual to unify up to four switches into a single logical stack, making it ideal for large campuses, smart buildings, or IoT ecosystems.
Key Features for Modern Networks
- Multigigabit PoE+ Ports: Supports 1/2.5/5Gbps auto-negotiation, enabling seamless upgrades to Wi-Fi 6/6E APs without rewiring.
- High PoE+ Capacity: Delivers 30W per port (740W total) for devices like PTZ cameras, AV systems, and digital kiosks.
- 10G Uplinks: The 4x10G SFP+ ports ensure ample bandwidth for data-heavy applications like 4K video streaming or cloud-based collaboration tools.
- DNA Advantage Licensing (A++): Unlocks Software-Defined Access (SDA), Encrypted Traffic Analytics (ETA), and Cisco Stealthwatch integration, enabling zero-trust security and AI-driven threat detection.
Licensing and Cost Considerations
The “A++” licensing tier combines DNA Essentials and Advantage into a perpetual model, offering lifetime access to automated policy enforcement, predictive analytics, and compliance management. This eliminates recurring subscription costs while ensuring alignment with frameworks like NIST and ISO 27001.
Addressing Critical User Questions
Q: Does this switch support PoE++ (60W/90W)?
No—it is limited to 802.3at (30W per port). For higher power requirements, consider the Catalyst 9300 series with UPoE/UPoE+.
Q: Can the 10G uplinks use 1G transceivers?
Yes—the SFP+ ports are backward-compatible with 1G/10G optics, allowing cost-effective migration from legacy infrastructure.
Q: How does A++ licensing enhance security?
| Feature | A++ Licensing | Base Licensing (A) |
|---|---|---|
| Threat Detection | ETA, Stealthwatch | Basic ACLs |
| Access Control | SDA, Zero-Trust Segmentation | VLAN-based segmentation |
Performance Comparison

Deploying this switch in a corporate campus with 500+ Wi-Fi 6E APs highlighted its strengths: the multigigabit ports eliminated bottlenecks for high-density user traffic, while ETA provided critical visibility into encrypted threats. However, organizations without dedicated network teams might find the A++ feature set overwhelming—simpler models like the 48PL-4G-A could suffice for basic needs. For enterprises prioritizing scalability, security, and power efficiency, this switch is a future-proof cornerstone.
