The Cisco Meraki MS390 series represents the ultimate evolution of cloud-managed edge switching, bringing together the unmatched operational simplicity of the Meraki browser dashboard with elite, resilient Cisco Catalyst switching hardware. Designed to anchor high-bandwidth business infrastructure, dense university spaces, and modern Wi-Fi 6/6E campuses, the MS390 provides robust physical performance without complex local CLI coding.

Engineered to protect networks against localized structural choke points, the MS390 series delivers lightning-fast stacking convergence alongside an automated Layer 3 dynamic routing backplane. It introduces high-density Multigigabit port models, customizable modular optical uplinks, and a toolless dual hot-swappable power architecture. With built-in Adaptive Policy technology, the MS390 protects user data by scaling group-based access rules cleanly across hundreds of sites simultaneously.

Technical Specifications

Uplink Customization: Modular bays accepting MA-MOD-8x10G (8x 10G SFP+) or MA-MOD-2x40G (2x 40G QSFP+) modules.
Physical Stacking Limits: Group up to 8 physical switch chassis into one logical framework with a massive 480 Gbps bandwidth capacity.
Power Redundancy: Two dedicated slots for hot-swappable modular AC power supply units (N+1 layout support).
Power Pooling: StackPower connects up to 4 switches in a loop to dynamically distribute power across units if an internal module drops.
Security & Encryption: Hardware-anchored Secure Boot alongside full, native wire-rate MACsec-256 cryptographic protection.
Warranty Lifecycle: Protected by Meraki’s comprehensive Lifetime Hardware Warranty with advanced unit shipping. [1, 2, 3, 4, 5]
