Cisco Catalyst C9300-48UXM-M Full Official English Description

1. Product Brief Overview

The Cisco Catalyst C9300-48UXM-M (shortened as C9300-48UX-M) is a 1 rack-unit (1RU) stackable cloud-managed Multigigabit UPOE enterprise access switch within the Catalyst 9300-M hybrid platform lineup, also named Meraki-managed Catalyst 9300 series switch. It shares identical copper downlink hardware with fixed-uplink C9300-48UX-A/E models but adopts a modular uplink card slot instead of built-in SFP+ ports. The suffix "-M" denotes Meraki cloud-native management architecture, operated via Meraki Dashboard with term-based subscription licensing rather than traditional perpetual Network Essentials/Advantage licenses for standalone IOS XE deploymentsCisco Meraki. Optimized for dense Wi-Fi 6/6E APs, high-power IP cameras, digital signage and campus IoT, it combines StackWise-480 stacking, StackPower power pooling, full Multigigabit copper speeds and flexible modular uplink expansion under unified Meraki cloud orchestration.
