Description
A 2U, 64-port 100GbE Cumulus Linux switch built on Spectrum-3. The CS2RC configuration uses QSFP28 cages, dual AC power supplies and connector-to-power airflow. NVIDIA documents the SN4600C family in DGX BasePOD management and Ethernet-storage designs.

Product questions & answers

What airflow and power configuration does CS2RC specify?

The exact ordering row specifies C2P airflow and two AC power supplies. The forward-airflow CS2FC is a different order code. Match fans and supplies to the chassis and airflow requirement.

How is SN4600C used in NVIDIA’s DGX BasePOD guide?

The H200/H100 guide uses a pair of SN4600C switches for in-band management and provisioning, with bonded host connections and MLAG. The guide identifies the model family, not the CS2RC airflow suffix.

Is the typical 466 W figure a rack-power maximum?

No. The SN4600C figure is typical power measured with passive cables under the stated ATIS condition. Facilities sizing must account for the intended configuration, optics, power feeds and redundancy rather than treating that typical figure as a maximum.

What software and lifecycle does NVIDIA list for CS2RC?

The ordering table specifies Cumulus Linux and marks CS2RC MP (Mass Production). This does not establish the supplied unit’s installed release, software entitlement, stock or warranty. Preserve those as separate commercial and deployment checks.

Can SN4600C have a documented storage-network role?

NVIDIA’s BasePOD hardware overview lists SN4600C for Ethernet-attached storage and QM9700 for the alternative InfiniBand storage fabric. This establishes a design option, not a guarantee for every storage array or workload. Validate the storage vendor’s networking requirements.

Is MSN4600-CS2RC the 200GbE SN4600 model?

No. CS2RC is the 100GbE SN4600C configuration with 64 QSFP28 cages. The 200GbE VS2RC model is a separate order code with QSFP56 and is listed in the legacy EOL section.
