Each MS390 model brings something different. The 24-port versions offer flexible PoE+, UPoE, or multigig UPoE ports with modular 10/40G uplinks. Stepping up to higher density, the 48-port variants—like the 2.5G UPoE and 5G UPoE configurations—combine broad device support with resilient StackPower and lightning-fast stacking up to 480 Gbps. Behind the scenes, Adaptive Policy adds dynamic, over-the-wire traffic classification into security groups like “Guest” or “IoT,” all managed via natural language in the Meraki dashboard.

NetworkTigers lists MS390 switches, which are available in refurbished, used, and new conditions. Refurbished units are restored and verified; used models are validated for everyday production use; new ones arrive sealed. All come with real inventory and a 365-day warranty for fast deployment with confidence.

Explore the Cisco Meraki MS390 Switches – Refurbished, Used, New collection to anchor your campus or branch network with performance, segmentation, and Meraki cloud simplicity—all without the baggage.
