NVIDIA Mellanox® MSX1710-BS2R2 36-Port 40GbE QSFP+ Open Ethernet Switch, 1U Standard Depth: This is a 1U fully-managed Open Ethernet spine/leaf switch with 36 QSFP+ ports built on the Mellanox SwitchX-2 ASIC (SX1710 family), supporting line-rate 40GbE on every port. The unit ships with two power supplies for 1+1 redundancy and C2P (connector-to-power) airflow. This is a switch only — rail kit, transceivers, and DAC cables are not included unless explicitly listed. This is a refurbished unit, professionally tested by T.E.S IT-SOLUTIONS.
Engineering Context
The SX1710 silicon delivers 36 line-rate 40GbE ports for 1.44 Tb/s of unidirectional port bandwidth (2.88 Tb/s bidirectional non-blocking) with cut-through forwarding for low end-to-end latency. Each QSFP+ port can be split into 4x10GbE breakout where supported by firmware and a breakout DAC, allowing up to 144 x 10GbE downstream connections from a single 1U device. C2P (connector-to-power) airflow is the standard hot-aisle/cold-aisle direction for racks where the cold aisle faces the port side. Dual PSUs provide 1+1 power redundancy.
Deployment & Use Cases
Spine layer in 40GbE leaf-spine fabrics. High-density top-of-rack switch where 36 x 40GbE downlinks (or up to 144 x 10GbE via breakout) are required in a single 1U slot. Aggregation in 40GbE Ethernet HPC clusters running MLNX-OS. End-of-row aggregation in mid-size enterprise data centers. Continuity for established SwitchX-2 deployments standardized on MLNX-OS.

Compatibility & Hard Constraints
Compatible with QSFP+ 40GbE transceivers, MFA1A00/MC2210 active optical cables, MC2207-series passive copper QSFP+ DACs, and standard 4x10G QSFP+-to-4xSFP+ breakout DACs. Operates as a leaf or spine in NVIDIA Spectrum-led Ethernet fabrics for protocol-compatible ports. Not an InfiniBand switch — InfiniBand HCAs cannot peer with this unit. Does not support 100GbE on its native ports; 100GbE requires Spectrum-based hardware. C2P airflow direction must align with rack hot-aisle/cold-aisle orientation; mixing airflow directions in one rack creates thermal recirculation. Rail kit must be ordered separately for full-depth cabinet installation.
Why Choose T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS verifies all 36 QSFP+ ports under load, validates dual-PSU operation, and re-images the device to a tested MLNX-OS baseline before shipment. We provide expert consultation on Open Ethernet fabric design, global shipping, and a comprehensive warranty. Orders ship within 1–3 business days from confirmation.
