NVIDIA Mellanox MSN2410-BB2R Spectrum 1U Open Ethernet Switch, 48× SFP28 + 8× QSFP28: This is a 1U top-of-rack Open Ethernet switch built on the NVIDIA Spectrum (Gen 1) ASIC. It provides 48 ports of 1/10/25GbE SFP28 and 8 ports of 40/100GbE QSFP28 in a fixed-port configuration. The BB2R variant ships with ONIE preloaded and uses C2P (connector-to-power, port-side intake) airflow. This is not a modular chassis switch and is not pre-loaded with NVIDIA Onyx; the ONIE bootloader allows installation of a supported network operating system. This is a refurbished unit.
Engineering Context
The MSN2410 (SN2410) is positioned as a high-density 25GbE leaf with 100GbE uplinks, providing 3.2 Tbps switching capacity and port-to-port latency in the 300 ns range typical of Spectrum-1 silicon. The 48 SFP28 ports support 1/10/25GbE per-port speed selection, while the 8 QSFP28 ports support 40GbE and 100GbE and can be used for spine uplinks or 4×25GbE breakout for additional access density. Dual hot-swappable power supplies and N+1 fan trays reduce single-point-of-failure exposure. The BB2R airflow direction (C2P) is intended for racks where the cold aisle faces the port side of the switch.
Deployment & Use Cases
Top-of-rack leaf switching for high-density 25GbE servers in spine-leaf data center fabrics. Hyperconverged infrastructure running VMware vSAN, Microsoft Storage Spaces Direct, or Nutanix AHV with 25GbE NICs. Storage networks for NVMe-oF and iSCSI over Ethernet. RoCE v2 fabrics for AI/ML training clusters where deterministic low-latency Ethernet switching is required. Replacement of legacy 1/10GbE ToR switches in data center modernization projects.

Compatibility & Hard Constraints
The MSN2410-BB2R is an Ethernet-only switch — it is not a VPI device and does not support InfiniBand. SFP28 cages accept SFP28, SFP+, and SFP transceivers and DACs at compatible speeds, but not QSFP-form optics. QSFP28 cages accept QSFP28 and QSFP+ optics/DACs but not SFP-form modules. The C2P airflow direction must match the data-center hot/cold aisle layout — installing it in a rack designed for P2C airflow will cause hot-air recirculation. ONIE-only shipment means a network OS must be installed before production use; Onyx, Cumulus, or SONiC licensing/support is not included with a refurbished unit and must be sourced separately if required.
Frequently Asked Questions (FAQ)
Q. What is the MSN2410-BB2R?
The MSN2410-BB2R is a Spectrum-based Open Ethernet switch with 48 SFP28 ports at 25GbE and 8 QSFP28 uplinks at 100GbE, running Onyx OS, 1U.
Q. Can it run other network operating systems besides Onyx?
As an ONIE-compatible platform, it can also accept Cumulus Linux or SONiC.
