Manufacturer Part #: MS390-48UX-HW
Cisco Meraki MS390-48UX 48-Port Multigigabit UPoE Switch — 490 W PoE Budget, 36 × 2.5G + 12 × 10G, 580 Gbps, 1U Rack
The Cisco Meraki MS390-48UX delivers 48 multigigabit UPoE ports — 36 at up to 2.5 Gbps and 12 at up to 10 Gbps — with a 490 W PoE budget for next-generation wireless and endpoint deployments. A 580 Gbps non-blocking switch fabric and 431.54 Mpps forwarding rate provide wire-speed performance even under heavy mixed traffic loads. Modular uplinks accept 10G SFP+ or 40G QSFP+ modules, and 480 Gbps hardware stacking integrates with other MS390 units for a unified, cloud-managed stack. Cisco StackPower and Adaptive Policy segmentation round out the enterprise feature set.
