Spectrum-3 SN4000 Switches Overview

Spectrum-3 SN4000 Switches includes five NVIDIA Open Ethernet systems based on the Spectrum-3 ASIC. The category spans 100GbE, 200GbE, and 400GbE platforms with QSFP28, QSFP56, or QSFP-DD interfaces in 1U and 2U standard-depth chassis. All five configurations include an x86 management CPU, two AC power supplies, P2C airflow, and a rail kit. Available software options include NVIDIA Onyx and Cumulus Linux, while port configurations range from 32 to 64 front-panel interfaces for enterprise and data center leaf and spine Ethernet fabrics.

MSN4600-CS2F is a 2U Spectrum-3 100GbE Open Ethernet switch with 64 QSFP28 ports and 6.4Tb/s of throughput. It runs NVIDIA Onyx on an x86 management CPU and includes two AC power supplies, a standard-depth chassis, P2C airflow, and a rail kit. The 64-port configuration supports dense 100GbE connectivity in enterprise and data center spine networks.

MSN4600-CS2FC provides the same 2U hardware configuration with Cumulus Linux. It includes 64 QSFP28 ports supporting up to 100GbE per port, 6.4Tb/s of throughput, an x86 management CPU, and two AC power supplies. The standard-depth chassis uses P2C airflow and is supplied with a rail kit for high-density Ethernet spine deployments.

MSN4600-VS2FC is a 2U Spectrum-3 200GbE Open Ethernet switch with 64 QSFP56 ports and 12.8Tb/s of throughput. It runs Cumulus Linux and incorporates an x86 management CPU, two AC power supplies, standard-depth construction, P2C airflow, and a rail kit. Its higher per-port speed supports 200GbE spine and high-density aggregation fabrics.

MSN4700-WS2F is a 1U Spectrum-3 400GbE Open Ethernet switch with 32 QSFP-DD ports and 12.8Tb/s of throughput. The system runs NVIDIA Onyx and includes an x86 management CPU, two AC power supplies, a standard-depth chassis, P2C airflow, and a rail kit. Its compact 32-port design supports 400GbE leaf, spine, and inter-switch connectivity.

MSN4700-WS2FC combines the 1U SN4700 hardware platform with Cumulus Linux. It provides 32 QSFP-DD ports supporting up to 400GbE per port and 12.8Tb/s of throughput. The switch includes an x86 management CPU, two AC power supplies, standard-depth construction, P2C airflow, and a rail kit for high-speed leaf and spine Ethernet networks.

FAQ

Which SKU gives me 64 native 100GbE ports?

Choose MSN4600-CS2F with Onyx or MSN4600-CS2FC with Cumulus Linux. Both provide 64 QSFP28 ports in a 2U chassis. The required network operating system determines which SKU fits the deployment.

What changes with the 200GbE MSN4600-VS2FC?

Its native port rate increases to 200GbE, and its 64 front-panel ports use QSFP56 rather than QSFP28. It remains a 2U switch and comes with Cumulus Linux. Match all transceivers and cables to the QSFP56 port configuration.

When does the 1U SN4700 make more sense?

SN4700 is the appropriate platform when the network requires native 400GbE QSFP-DD ports in a 1U chassis. It provides 32 ports, compared with the 64-port, 2U layouts of SN4600 and SN4600C.

How are the Onyx and Cumulus Linux versions identified?

MSN4600-CS2F and MSN4700-WS2F use Onyx. MSN4600-CS2FC, MSN4600-VS2FC, and MSN4700-WS2FC use Cumulus Linux. Confirm the full SKU suffix rather than selecting by the SN4600 or SN4700 family name alone.

Can one transceiver type be used across this category?

No single transceiver type covers every configuration. The switches use QSFP28, QSFP56, or QSFP-DD ports and support different link rates. Match each transceiver or cable to the selected switch, configured speed, supported port mode, and peer interface.
