FAQs

Q: What is multi-gigabit (mGig) and which ports support it on the MS355-24X?
A: The MS355-24X features 8 multi-gigabit ports that auto-negotiate at 100Mbps, 1Gbps, 2.5Gbps, 5Gbps, or 10Gbps speeds over standard RJ45 copper cabling. These mGig ports are designed to support the high bandwidth requirements of Wi-Fi 6/6E access points without requiring fiber cabling. The remaining 16 ports are standard gigabit Ethernet. For best mGig performance, use Cat6 or Cat6A cabling.

Q: Can I use the uplink ports as 10G SFP+ or 40G QSFP+?
A: Yes, the MS355-24X provides flexible uplink options: you can configure the uplinks as either 4x 10G SFP+ ports or 2x 40G QSFP+ ports depending on your aggregation needs. The configuration is flexible and can be adapted based on your network topology.

Q: Does this switch require a Meraki license to operate?
A: Yes, the MS355-24X requires a Meraki Enterprise license (LIC-MS355-24X-xYR) for operation. The license enables cloud management, Layer 3 routing features, advanced security policies, Layer 7 traffic analytics, and centralized monitoring through the Meraki Dashboard. Licenses are sold separately and available in 1, 3, 5, 7, and 10-year terms.

Q: How does hardware stacking work on the MS355 series?
A: The MS355-24X includes 2 dedicated 100G QSFP28 stacking ports that provide 400 Gbps of stacking bandwidth. You can physically stack up to 8 MS355 switches using optional MA-CBL-100G stacking cables (available in 0.5m, 1m, and 3m lengths). Stacked switches operate as a single logical switch with unified management, shared configuration, and seamless failover.

Q: What is the maximum PoE power available per port?
A: The MS355-24X supports PoE++ (UPoE) with up to 60W per port, providing sufficient power for the most demanding devices including high-power Wi-Fi 6E access points, PTZ cameras, and video conferencing endpoints. The total PoE budget is 740W with a single power supply, or up to 1,440W when operating in combined power mode with dual power supplies installed. PoE power is intelligently allocated using CDP and LLDP protocols.
