Purpose-built switching

The NVIDIA MSN2201-CB2RC is a managed 1U rackmount switch that combines 48 RJ45 ports with four QSFP28 uplinks. It runs Cumulus Linux on an Intel x86 dual-core CPU and is aimed at data-centre operators who need dense 1GBase-T access alongside 100GbE aggregation.

Build and connectivity

Dual AC power supplies feed a typical draw of 98W with passive cables. The chassis measures 43.9mm high, 428mm wide and 432mm deep, weighing 7.410kg, and uses C2P airflow with a supplied four-post rail kit. Eight gigabytes of ECC DDR4 SO-DIMM and a 20GB M.2 SSD support the on-board operating system.

Interface limits

RJ45 ports operate at 10/100/1000Mbase-T while each QSFP28 port supports 1/10/25/40/50/56/100GbE. Throughput reaches 448GB/s across the Spectrum ASIC. The switch is rated for 0 to 40°C operation and 10% to 85% non-condensing humidity. Buyers who need PoE or higher port counts must look elsewhere.

Questions about this item

What speeds do the QSFP28 ports actually support?

Each QSFP28 port runs at 1, 10, 25, 40, 50, 56 or 100 GbE depending on the transceiver or cable you fit.

How much rack depth does the 1U chassis need?

The unit is 432 mm (17 in) deep and ships with a four-post rail kit for standard cabinets.

How do I get Cumulus Linux running after racking the switch?

Connect to the management port, power on, then run the ONIE installer to load Cumulus Linux; the step most people miss is selecting the correct boot option in the ONIE menu.
