Cisco Catalyst C9200L-48PXG-2Y-A | 48-Port PoE+ mGig Switch | 2 x 25G Uplinks | Network Advantage

Overview

The cisco c9200l-48pxg-2y-a is a high-density multigigabit PoE+ enterprise access switch purpose-built for scalable campus networks, next-generation Wi-Fi 6/6E wireless rollouts, smart building infrastructure, and converged wired-wireless environments. It features 48 robust power-delivery access ports, including 8 specialized multigigabit ports (100M/1G/2.5G/5G/10G) and 40 line-rate Gigabit Ethernet ports. This unique port matrix allows this powerful c9200l-48pxg-2y-a unit to function as a highly versatile cisco 10gbe switch aggregation engine right at your network edge, driving full throughput for high-performance access points, intensive IP surveillance arrays, and mission-critical VoIP deployments.

The platform natively integrates 2 x 1/10/25G SFP28 high-speed uplinks (backward compatible), ensuring lightning-fast aggregation to your core layers while completely eliminating backhaul bottlenecks. With a massive default 740W PoE budget (dynamically expandable to 1440W with dual power supplies), it supports dense device environments seamlessly. Built on Cisco's programmable UADP 2.0 Mini ASIC and running Cisco IOS XE with a full Network Advantage license, it unlocks comprehensive Layer 3 dynamic routing, macro-segmentation, and full SD-Access fabric readiness.

2. 2 x 25G Uplinks for Future-Proof Aggregation

Includes 2 integrated SFP28 uplink slots natively supporting 1G, 10G, and line-rate 25G aggregation, delivering low-latency backbone connectivity directly to campus core switches or data center aggregates.

3. High-Performance Switching Architecture

Delivers a massive 340 Gbps non-blocking switching fabric capacity paired with a wire-speed 252.97 Mpps forwarding performance rate, ensuring smooth data flow for intensive cloud applications, streaming media, and concurrent real-time traffic workloads.

4. 12 MB Packet Buffer for Congestion Handling

Features an upgraded 12 MB deep shared packet buffer-double the buffer size of standard enterprise Gigabit models (6 MB). It is highly optimized to absorb sudden microbursts, protect latency-sensitive database streams, and eliminate drop anomalies across financial systems or high-density wireless nodes.

5. Scalable PoE Power up to 1440W

Offers a solid default 740W PoE inline power budget (via 1 x PWR-C5-1KWAC module), dynamically scalable up to a massive 1440W of total power injection with dual PSUs to continuously energize a fleet of APs, security cameras, smart sensors, and VoIP devices.
