Meraki MS390-48UX2-HW | Meraki MS390 48-Port 5G UPoE Switch, 645W, Modular

Q: What speeds do the ports support on the MS390-48UX2-HW?
A: All 48 RJ45 ports are multi-gigabit capable, supporting 100Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps speeds. This makes the switch ideal for connecting Wi-Fi 6 access points and other high-bandwidth devices without needing costly cable upgrades.

Q: How many devices can the 645W PoE budget power simultaneously?
A: The 645W base PoE budget supports Universal PoE (up to 60W per port), allowing approximately 10 ports at full 60W UPoE simultaneously, or more devices at lower power levels. An optional secondary power supply increases the total PoE budget to 1745W for greater capacity.

Q: Can the MS390-48UX2-HW be stacked with other switches?
A: Yes, up to 8 MS390 switches can be physically stacked using dedicated 120G stacking ports with 480 Gbps total stacking bandwidth. The switch also supports virtual stacking through the Meraki dashboard for managing thousands of ports as a single logical entity across multiple sites.

Q: What uplink options are available for this switch?
A: The MS390-48UX2-HW features a modular uplink slot that accepts either MA-MOD-2X40G (2x 40G QSFP+) or MA-MOD-4X10G/MA-MOD-8X10G (4 or 8x 10G SFP+) modules, providing flexible high-speed connectivity to aggregation or core layers.

Q: Does this switch require licensing to operate?
A: Yes, Meraki switches require cloud licensing to function. The MS390 series offers Enterprise and Advanced license tiers in 1, 3, 5, 7, or 10 year terms. Licensing is sold separately and provides access to cloud management, security features, and firmware updates.
