Comprehensive Product Overview

The Cisco Catalyst C9300L-48P-4G-E is a high-performance, stackable Layer 3 Gigabit Ethernet PoE+ access switch purpose-built for modern enterprise, campus, IoT, and wireless networks. It features 48 fixed 10/100/1000BASE-T RJ45 PoE+ ports (delivering up to 30W per port) to power IP phones, Wi-Fi 6/6E access points, IP cameras, and IoT devices without separate power adapters, plus 4 dedicated 1G SFP uplink ports for high-speed fiber/copper aggregation to core/distribution layers—all in a compact 1RU rack-mount form factor.

Powered by Cisco Unified Access Data Plane (UADP) 2.0 architecture and Cisco IOS XE, this switch delivers wire-speed performance, advanced security, and cloud-manageability. It supports StackWise-320 stacking (up to 8 switches, 320 Gbps stacking bandwidth) to scale port density and simplify management, making it ideal for high-density PoE deployments. The included Network Essentials license provides core enterprise features: static/RIP/OSPF routing, VLANs, QoS, MACsec encryption, and Energy Efficient Ethernet (EEE).

Designed for security, IoT, mobility, and cloud integration, it aligns with Cisco DNA Center and SD-Access for intent-based networking and zero-trust security, offering investment protection, operational efficiency, and reliability for businesses needing a cost-effective, PoE-rich access switching solution.
