Cisco Catalyst 9300 Series Switches (C9300L-48T-4G-E)

Built for security, IoT, mobility, and cloud

The C9300L-48T-4G-E 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. Catalyst 9300 Series switches form the foundational building block for Software-Defined Access (SD-Access), Cisco’s lead enterprise architecture. At up to 1TB, 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 Wi-Fi 6 and 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 (C9300L-48T-4G-E) 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 Power over Ethernet Plus (PoE+), 60W Cisco Universal Power over Ethernet (Cisco UPOE), and 90W Cisco UPOE®+ ports. The switches are based on the Cisco Unified Access™ Data Plane 2.0 (UADP) architecture, which protects your investment and allows a larger scale and higher throughput. Catalyst 9300X models are based on a new ASIC, UADP 2.5sec, which adds Crypto support in hardware, including IPSEC. 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

The exponential growth of IoT devices, pervasive mobility, and the rise of cloud adoption have intensified the demand for robust, secure, and automated network infrastructures. At the core of addressing these challenges is Cisco’s Digital Network Architecture (DNA) with Software-Defined Access (SD-Access). This innovative fabric integrates cutting-edge hardware and software to simplify network operations, enabling policy-based automation from edge to cloud. Features such as unified management, network virtualization, and context-based analytics empower organizations to optimize network performance while streamlining IT efforts. Complementing this is Cisco DNA Software, offering flexible licensing, seamless upgrades, and enhanced service assurance—ensuring businesses can adapt, scale, and innovate effectively. By leveraging these technologies, solutions like the C9300L-48T-4G-E simplify network management and drive revenue growth by accelerating business service deployment.
