About the Cisco Meraki MS390-48UX2 Switch
The Cisco Meraki MS390-48UX2 Switch delivers 48 access ports with MultiGigabit speed support ranging from 100M to 10G, backed by two modular uplink bays capable of supporting optional 10G, 25G, or 40G modules. This 1U rack-mount design achieves a switching capacity of 480 Gbps and operates as a Layer 2 and Layer 3 device, making it ideal for organizations seeking flexible, high-density port aggregation with scalable uplink architecture. The MS390-48UX2-HW (part number) integrates the Cisco UADP 3.0 Mini forwarding ASIC to deliver consistent performance across mixed-speed workloads, while support for up to 8 switches per stack via dedicated stack ports enables seamless network expansion without sacrificing manageability.
Network engineers and IT procurement teams deploy the Cisco Meraki MS390 Series for campuses, branch offices, and enterprise data center edge environments where cloud-managed simplicity meets enterprise-grade switching capability. Built-in Power over Ethernet (PoE++) support—covering IEEE 802.3af, 802.3at, and 802.3bt standards—with a total PoE budget of 1440 W eliminates the need for separate power infrastructure for networked devices. The cloud-based Cisco Meraki Dashboard management model removes the operational burden of on-premises controllers, while advanced security features including MACsec (802.1AE), Dynamic ARP Inspection, DHCP Snooping, and 802.1X port-based access control provide defense against layer 2 threats. Static routing and OSPF routing protocol support (with appropriate licensing) enable flexible network topology design, and full Cisco SD-Access fabric edge compatibility via Cisco DNA Center positions this switch within modern intent-based networking architectures.
Redundant power supply support ensures continuous availability for mission-critical deployments, while VLAN support via 802.1Q enables logical network segmentation across all 48 access ports. Whether you are modernizing a campus LAN or standardizing branch connectivity, the MS390-48UX2-HW combines density, speed, and cloud intelligence in a compact form factor.

Frequently Asked Questions about Cisco Meraki MS390-48UX2 Switch
Does the Cisco Meraki MS390-48UX2 Switch support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations in advance, or provide remote commissioning. Add commissioning to your RFQ.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises later.
Is the support global?
Yes — manufacturer hardware support is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
