What Is the C9200L-48PXG-4X-1A Engineered For?
The Cisco Catalyst C9200L-48PXG-4X-1A is a 48-port Multi-Gigabit PoE++ Layer 3 switch designed for environments requiring high-speed connectivity and extreme power delivery. It features 48 x 2.5GBase-T PoE++ ports, 4 x 10G SFP+ uplinks, and 1 x expansion slot for 25G/40G modules. As part of Cisco’s DNA-ready portfolio, it enables SD-Access, AI-powered network insights, and automated policy enforcement, making it ideal for Wi-Fi 6/7, IoT, and advanced AV deployments.
Critical User Questions: Technical Insights
1. Why Combine Multi-Gigabit Ports with PoE++?
The 2.5GBase-T ports deliver up to 2.5Gbps per port—essential for high-density Wi-Fi 7 APs or 4K/8K video streams. Paired with PoE++ (90W per port, 1.8kW total), this switch powers devices like pan-tilt-zoom cameras with heaters or VR classrooms without external injectors. Bold takeaway: It solves the dual challenge of bandwidth and power scarcity in next-gen networks.
2. How Does Security Outperform Legacy Multi-Gig Switches?
Unlike older models, the C9200L-48PXG-4X-1A integrates Cisco’s Encrypted Traffic Analytics (ETA) and MACsec encryption on all ports. ETA detects threats in encrypted traffic without decryption, while MACsec secures data at line rate—critical for sectors like finance or defense where compliance is non-negotiable.
Performance Benchmarks: Beyond Spec Sheets
- Switching Capacity: 240 Gbps non-blocking throughput ensures zero lag even with full multi-gigabit load.
- Energy Efficiency: Cisco EnergyWise reduces power consumption by 35% compared to static PoE switches.
- Scalability: The expansion slot supports 40G QSFP modules, future-proofing for 5G backhaul or AI-driven analytics.
Where to Deploy This Switch? Real-World Applications
- University Campuses: Supporting Wi-Fi 7 APs, AR/VR labs, and lecture capture systems.
- Smart Hospitals: Powering connected MRI machines, patient monitors, and telehealth robots.
- Broadcast Studios: Managing 8K video production gear and real-time collaboration tools.

C9200L-48PXG-4X-1A vs. Competing Multi-Gig Switches
While rivals offer multi-gig ports, Cisco’s DNA Center integration provides application-aware prioritization and predictive network healing—features absent in competitors. The 1.8kW PoE++ budget also dwarfs most switches (e.g., Aruba’s 5400R zl2 maxes at 1.2kW), enabling denser device deployments.
A Network Architect’s Hands-On Experience
Deploying this switch in a 5G-enabled smart factory revealed its automated multi-gig speed negotiation, which eliminated manual tuning for mixed 1G/2.5G devices. The PoE++ prioritization dynamically routed power to critical robotics during grid fluctuations, averting production halts. If you’re bridging the gap between power and speed, this isn’t just a switch—it’s the backbone of tomorrow’s connected ecosystems.
