Description
Condition: NEW — Brand new, factory-sealed unit. Manufacturer Part #: MS355-24X2-HW
Cisco Meraki MS355-24X2 24-Port All-mGig UPoE Switch — 24 × 10G mGbE RJ45, 740 W UPoE, 400G Physical Stack, 1U Rack
The Cisco Meraki MS355-24X2 delivers an all-multigigabit 24-port RJ45 access layer with every port capable of negotiating 100M through 10G speedsremoving the 1G bottleneck entirely. Two 40G QSFP+ and four 10G SFP+ uplinks feed a 640 Gbps non-blocking fabric, while 400G dedicated hardware stacking ports allow up to four units to share a single logical control plane. The 740 W UPoE budget supports demanding endpoints including multi-radio 802.11ax APs, PTZ cameras, and UPoE-class IP phones without an external power injector.

Best Used For
Ideal for high-density environments where every endpoint demands speeds beyond 1G—such as Wi-Fi 6E deployments in lecture halls, healthcare imaging floors, or media production studios where maximum per-port throughput and UPoE device power are both required simultaneously.
