Meraki MS390-48P-HW | Meraki MS390 48-Port Gigabit PoE+ Switch, 740W, Modular Uplinks

Q: What license is required for the MS390-48P-HW to operate?
A: The MS390-48P-HW requires a Meraki Enterprise or Advanced cloud license to function. Licenses are sold separately in 1, 3, 5, 7, or 10-year terms and enable cloud-based management through the Meraki Dashboard. The Advanced license tier adds features like Adaptive Policy and enhanced security capabilities.

Q: What uplink modules are compatible with this switch?
A: The MS390-48P-HW features one modular uplink slot that accepts MA-MOD-2X40G (2x 40GbE QSFP+) or MA-MOD-8X10G (8x 10GbE SFP+) modules. These uplinks provide high-speed connectivity to aggregation or core layers. Modules are sold separately and allow flexible network design based on bandwidth requirements.

Q: Can I increase the PoE budget beyond 740W?
A: Yes, the MS390-48P-HW supports an optional secondary power supply for redundancy and increased PoE capacity. With an upgraded MA-PWR-1100WAC power supply, the total PoE budget can reach up to 1152W, enabling more devices to receive full PoE+ power simultaneously across the 48 ports.

Q: How many MS390 switches can be stacked together?
A: You can physically stack up to 8 MS390 switches using dedicated 120G stacking cables (sold separately), delivering 480 Gbps of stacking bandwidth. The Meraki platform also supports virtual stacking, allowing thousands of switch ports across multiple sites to be managed as a single logical entity through the cloud dashboard.

Q: Is the MS390-48P-HW suitable for Wi-Fi 6 deployments?
A: Yes, the MS390-48P-HW is specifically designed to support high-density Wi-Fi 6 (802.11ax) access point deployments. With 740W of PoE+ capacity and modular 10G/40G uplinks, it provides sufficient power and bandwidth for modern wireless infrastructure, ensuring seamless connectivity for high-speed wireless applications.
