The MS355-24X offers 16 1GbE RJ45 ports plus 8 mGig (100M-10G) RJ45 ports and up to 352 Gbps of switching capacity. The MS355-48X2 steps up to 24 1GbE RJ45 ports and 24 mGig RJ45 ports, with switching capacity up to 688 Gbps. Both models share the same 4x 10GbE SFP+ ports, 2x 40GbE QSFP+ uplinks, and 740W UPoE budget — the choice mainly comes down to port count and total mGig density needed for your access point or endpoint deployment.

Yes. Every MS355 model provides a 740W Universal PoE (UPoE) budget, supplying up to 30W per port under PoE+ or up to 60W per port under UPoE — enough to power Wi-Fi 6/6E access points, PTZ cameras, and other high-draw endpoints without an external injector.

Every MS355 switch includes 4x 10GbE SFP+ ports and 2x 40GbE QSFP+ ports for uplinks to your core or aggregation layer, giving you the flexibility to run 10G fiber for standard aggregation or 40G for higher-bandwidth backbone links.

Yes. Each MS355 includes two dedicated hardware stacking ports supporting up to 400 Gbps of stacking bandwidth, allowing multiple physical switches to operate and be managed as a single logical switch for simplified administration and added resiliency.

Yes, the MS355 supports full Layer 3 switching, including OSPF dynamic routing, static routes, and IPv4/IPv6 ACLs, making it suitable for core and aggregation roles. As with all Meraki MS switches, the MS355 requires an active Meraki cloud license (typically Enterprise or Advanced Security tier) tied to the hardware for dashboard management, firmware updates, and support.
