MSN3420-CB2FC Mellanox 48-Port 25G SFP28 12-Port 100G QSFP28 Layer 3 Switch

The MSN3420-CB2FC is built for data centers and enterprise networks that require a balance of high port density and flexible uplink speeds. It's often found in environments where 25GbE connections are standard, but 100GbE uplinks are necessary to handle heavier traffic loads or aggregation tasks.

This switch is commonly used by IT professionals managing network infrastructure who need reliable Layer 3 routing alongside robust Layer 2 switching. Its back-to-front airflow suits rack designs with specific cooling requirements, making it practical in dense server rooms.

Key Features

• Offers 48 25GBase-X SFP28 ports suitable for server or storage connectivity
• Includes 12 100GBase-X QSFP28 ports for high-speed uplinks or stacking multiple switches
• Supports advanced Layer 3 features like OSPF, BGP, and static routing for complex network topologies
• Back-to-front airflow helps direct heat away in tightly packed rack setups
• Compact 1U size maximizes rack space without compromising performance

You’ll typically find this switch deployed in data center top-of-rack configurations or aggregation layers, where it manages traffic between servers and core infrastructure. Its combination of speed, manageable features, and cooling design helps maintain efficient, stable operation in demanding network environments.
