64-port QSFP28 100GbE switch

The NVIDIA MSN4600-CS2RC is a managed Layer 3 switch built on the Spectrum-3 ASIC. It delivers 6.4 Tb/s throughput across 64 QSFP28 ports in a 2U rackmount chassis. Dual AC power supplies and an Intel x86 CPU running Cumulus Linux provide a complete open Ethernet platform for data-centre fabrics.

Suited for high-density spine and leaf.

This switch fits spine-and-leaf deployments that need 64 ports of 100GbE in a single 2U unit with front-to-back airflow. It is not for buyers who need only a handful of ports, who require PoE for endpoint devices, or who operate outside the 0°C to 40°C operational temperature range.

64 QSFP28 ports at 100GbE line rate

The defining specification is the 64 QSFP28 interfaces operating at 100GbE each, giving 6.4 Tb/s aggregate switching capacity. If the design calls for fewer than 64 high-speed ports or a different form factor, this model will not match the requirement.

Questions about this item

How much rack depth does the 2U MSN4600-CS2RC require?

The chassis is 566.4 mm deep (22.3 inches), so allow at least that much usable depth plus cable clearance behind the rear panel.

Which rack-mount hardware is included with the switch?

A rail kit is supplied; attach the rails to the rack first, then slide the 14.64 kg unit in and secure the front brackets — skipping the rail step is the common error.

Are the dual AC power supplies hot-swappable for later replacement?

Yes, the two 100–240 Vac modules can be removed and replaced while the switch stays running, so a failed supply does not require downtime.
