Cisco Meraki MS390-48UX2 48-Port Multigigabit UPoE Switch — 645 W PoE Budget, Layer 3 Stackable, 640 Gbps, 1U Rack
The Cisco Meraki MS390-48UX2 offers 48 multigigabit UPoE ports (up to 5 Gbps each) with a 645 W PoE budget, meeting the power and bandwidth requirements of dense Wi-Fi 6 and advanced endpoint deployments. A 640 Gbps switching fabric and 476.19 Mpps forwarding rate deliver wire-speed performance across all 48 ports simultaneously. Like all MS390 models, it supports modular 10G SFP+ and 40G QSFP+ uplinks, 480 Gbps hardware stacking, StackPower, and full Meraki cloud management with Adaptive Policy. Hot-swappable PSU and fans ensure high availability in production environments.
