NVIDIA Mellanox MSX1710-BS2F2 SwitchX-2 36-Port 40GbE QSFP+ 1U Open Ethernet Switch, Dual PSU, Managed: This is a 1U managed Open Ethernet switch built on the NVIDIA Mellanox SwitchX-2 ASIC, equipped with 36 QSFP+ ports rated at 40GbE per port and a dual-PSU power configuration. It is an Ethernet switch — it is not an InfiniBand-only switch, not a 100GbE Spectrum platform, and not an unmanaged box. This unit is supplied refurbished in tested working condition.
Engineering Context. The SwitchX-2 silicon underlying the MSX1710 family delivers cut-through L2/L3 Ethernet forwarding with non-blocking 36x40GbE switching capacity (2.88 Tb/s). Each QSFP+ port can also operate as 4x10GbE breakout, giving the platform up to 144 logical 10GbE links when populated with breakout cables. The Open Ethernet design supports MLNX-OS as the native NOS and accepts ONIE-loaded third-party network operating systems on supported builds.
Deployment & Use Cases. Typical deployments include 40GbE leaf and spine layers in cloud and HPC fabrics, GPU and storage-pod top-of-rack switching, RoCE-accelerated storage backends (NVMe-oF, parallel filesystems), and aggregation tiers where high-radix 40GbE with 10GbE breakout is preferred over a mix of fixed switches.

Compatibility & Constraints. Pairs with QSFP+ DAC, AOC, and 40GBASE-SR4/LR4 optics from the Mellanox media list; 4x10GbE breakout requires QSFP-to-4xSFP+ breakout cables and a port configured for breakout in the NOS. The MSX1710 line is a 40GbE platform — it does not deliver 100GbE per port and is not a substitute for Spectrum-series (SN2000/SN3000) switches when 100GbE is required. Verify rack PDU capacity for dual-PSU operation and that the chosen NOS image matches the hardware revision.
