Cisco Meraki MS355-24X 24-Port Multigigabit UPoE Switch — 16 × 1G + 8 × mGig RJ45, 740 W UPoE, 400G Physical Stack, 1U Rack
The Cisco Meraki MS355-24X is a 24-port stackable access switch built for high-density wireless and wired environments that demand multigigabit throughput. Sixteen 1G RJ45 ports and eight multigigabit (100M/1G/2.5G/5G/10G) RJ45 ports combine with four 10G SFP+ and two 40G QSFP+ uplinks to provide a highly flexible connectivity tier. The 352 Gbps non-blocking switch fabric and 740 W UPoE budget make this an ideal platform for powering next-generation 802.11ax access points, IP phones, and high-draw IoT devices across branch and campus wiring closets.
