Description
Condition: NEW — Brand new, factory-sealed unit. Manufacturer Part #: MS355-48X2-HW
Cisco Meraki MS355-48X2 48-Port High-Density Multigigabit UPoE Switch — 24 × 1G + 24 × mGig RJ45, 740 W UPoE, 400G Physical Stack, 1U Rack
The Cisco Meraki MS355-48X2 provides 48 ports of mixed-speed access with half the ports delivering full multigigabit (100M/1G/2.5G/5G/10G) capability alongside 24 standard 1G ports. The 688 Gbps non-blocking switching fabric, dual 40G QSFP+ uplinks, and 400G hardware stacking backbone make this the highest-capacity model in the MS355 family. Three hot-swap fans and a dual removable PSU bay ensure continuous operation in mission-critical campus wiring closets serving dense 802.11ax wireless infrastructure.
