Cisco MS390 2x40GE Module MA-MOD-2X40G | Meraki, 40 GbE — MA-MOD-2X40G

Extend MS390 switching architectures with a dedicated 2x40GE module designed for high-speed uplink aggregation. In environments where access ports are no longer the constraint, this module helps preserve throughput between switch tiers and supports cleaner network segmentation at scale. For teams building Meraki-based campus or distribution layers, the module adds the bandwidth needed to move traffic efficiently toward core services, storage, and upstream switching paths. That matters when you are carrying virtualization traffic, large east-west flows, or concentrated user access across multiple closets. Because it is intended for configuration-based deployments, it fits organizations that want to standardize on a managed Meraki stack while keeping uplink design flexible. The result is a more capable switching platform without replacing the full chassis. For infrastructure teams, that is a smarter way to spend on bandwidth where it actually changes performance. Ideal For Add high-speed uplinks in a Meraki MS390 access or distribution closet Connect aggregation switches to core infrastructure with 40 GbE paths Support virtualization and storage traffic that needs higher uplink bandwidth Standardize modular uplink expansion across Meraki-managed campus networks Why This Product 1 Adds 2 x 40 GbE uplinks instead of forcing a chassis replacement 2 Supports higher aggregation bandwidth for Meraki MS390 designs 3 Fits configuration-driven enterprise deployments 4 Targets backbone and distribution bottlenecks directly
