• Managed 1U Rack-Mount Ethernet Switch
• 48 SFP28 Ports at 25 Gigabits per Second
• 12 QSFP28 Ports at 100 Gigabits per Second
• 60 Ports in Total
• Dual redundant, Hot-Swappable Power Supplies
• 200W Power consumption, Connector-to-Power (C2P) Airflow

The NVIDIA MSN3420-CB2RC is a managed 1U Ethernet switch providing 48 SFP28 ports at 25Gb/s plus 12 QSFP28 ports at 100Gb/s, for 60 ports in total. It consumes 200W, uses dual redundant hot-swappable power supplies, and moves air connector-to-power (C2P). A switch in this configuration aggregates 25GbE server links onto 100GbE uplinks, which is the standard leaf position in a modern datacenter fabric. Note the record holds only eight attributes, with no dimensions, weight, operating temperature range or supported network operating system recorded.

A 48-port 25GbE leaf switch sits at the top of the rack in datacenter and cloud deployments, connecting servers over 25GbE and aggregating that traffic onto 100GbE spine uplinks. Typical deployments are AI and HPC cluster fabrics, storage networks carrying RoCE traffic, virtualisation and container hosts, and enterprise private clouds migrating off 10GbE where 25GbE reuses the same cabling and optics economics. Airflow direction matters more than buyers expect: a connector-to-power unit must match the hot-aisle and cold-aisle orientation of the rack it goes into, and the wrong variant cannot simply be reversed in the field. Buyers should also confirm which network operating system and licence the unit ships with, since open switches of this type are sold with several software options.
