C9300-48U-E Overview

The Cisco® Catalyst® 9300 Series Switches are Cisco’s lead stackable enterprise switching platform built for security, IoT, mobility, and cloud. They are the next generation of the industry’s most widely deployed switching platform. The Catalyst 9300 Series switches form the foundational building block for Software-Defined Access
(SD-Access), Cisco’s lead enterprise architecture. At 480 Gbps, they are the industry’s highest-density stacking bandwidth solution with the most flexible uplink architecture. The Catalyst 9300 Series is the first optimized platform for high-density 802.11ac Wave2. It sets new maximums for network scale. These switches are also ready for the future, with an x86 CPU architecture and more memory, enabling them to host containers and run third-party applications and scripts natively within the switch.

The Catalyst 9300 Series is designed for Cisco StackWise® technology, providing flexible deployment with support for nonstop forwarding with Stateful Switchover (NSF/SSO), for the most resilient architecture in a stackable (sub-50-ms) solution. The highly resilient and efficient power architecture features Cisco StackPower®, which delivers high-density Cisco Universal Power Over Ethernet (Cisco UPOE®) and Power over Ethernet Plus (PoE+) ports. The switches are based on the Cisco Unified Access™ Data Plane 2.0 (UADP) 2.0 architecture which not only protects your investment but also allows a larger scale and higher throughput. A modern operating system, Cisco IOS XE with programmability offers advanced security capabilities and Internet of Things (IoT) convergence.

The foundation of Software-Defined Access

Advanced persistent security threats. The exponential growth of Internet of Things (IoT) devices. Mobility everywhere. Cloud adoption. All of these require a network fabric that integrates advanced hardware and software innovations to automate, secure, and simplify customer networks. The goal of this network fabric is to enable customer revenue growth by accelerating the rollout of business services.

The Cisco Digital Network Architecture (Cisco DNAâ„¢) with SD-Access is the network fabric that powers business. It is an open and extensible, software-driven architecture that accelerates and simplifies your enterprise network operations. The programmable architecture frees your IT staff from time-consuming, repetitive network configuration tasks so they can focus instead on innovation that positively transforms your business. SD-Access enables policy-based automation from edge to cloud with foundational capabilities.

Frequently Asked Questions

What power capabilities does the Cisco C9300-48U-E offer for connected endpoints? +
The C9300-48U-E features 48 ports of Universal Power over Ethernet (UPOE), delivering up to 60W per port. This capacity is ideal for powering high-draw devices like advanced Wi-Fi 6 access points, PTZ cameras, and desktop VDI endpoints directly through the switch, simplifying your cable management and power infrastructure requirements.
Does the C9300-48U-E support hardware stacking for increased density? +
Yes, this model supports Cisco StackWise technology, allowing you to stack up to eight switches in a single logical unit. This provides a unified control plane and high-speed backplane connectivity, enabling your network to scale seamlessly as port density requirements grow without increasing management overhead.
Which software license tier is included with the C9300-48U-E? +
This specific unit comes with the Network Essentials license. It provides foundational Layer 2 and Layer 3 routing capabilities, including OSPF, EIGRP, and RIP, which are sufficient for most standard enterprise access layer deployments. It establishes a robust baseline for wired and wireless network management.
Is the C9300-48U-E suitable for mission-critical enterprise environments? +
Absolutely. The Catalyst 9300 series is designed for high availability, featuring redundant power supplies and field-replaceable fan modules.
