Description
C9300-48UB-E Overview
The Cisco Catalyst 9300 Series switches are Cisco��s lead stackable enterprise switching platform built for security, IoT, mobility, and cloud. 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 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.
