NVIDIA Mellanox MSN2410-BB2F 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 BB2F variant ships with ONIE preloaded and uses P2C (power-to-connector, PSU-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) delivers 3.2 Tbps of switching capacity with 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 BB2F airflow direction (P2C) draws cool air in at the PSU side and exhausts at the port side, matching racks where the cold aisle faces the rear of the switch (PSU side).
Deployment & Use Cases
Top-of-rack leaf switching for high-density 25GbE compute 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 where deterministic low-latency Ethernet switching is required. Replacement of legacy 1/10GbE ToR switches in data center modernization projects with standard P2C airflow racks.

Compatibility & Hard Constraints
The MSN2410-BB2F is an Ethernet-only switch — it is not a VPI device and does not support InfiniBand. SFP28 cages accept SFP28, SFP+, and SFP transceivers/DACs at compatible speeds, but not QSFP-form optics. QSFP28 cages accept QSFP28 and QSFP+ optics/DACs but not SFP-form modules. The P2C airflow direction must match the data-center hot/cold aisle layout — installing it in a rack designed for C2P 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.
