NVIDIA Mellanox MSX1400-BS2R2 1U Open Ethernet Switch, 48x SFP+ 10GbE + 12x QSFP+ 40GbE, Dual PSU: This is a 1U Open Ethernet switch built on the SwitchX-2 ASIC, presenting 48 SFP+ ports at 10GbE and 12 QSFP+ uplink ports at 40GbE. It runs MLNX-OS on an integrated x86 quad-core CPU, is configured with two AC power supplies, and uses Connector-to-PSU (C2P) airflow. This is a fixed-port leaf/ToR aggregation switch, not a modular core chassis. This is a refurbished unit tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MSX1400-BS2R2 provides 1.92 Tb/s of switching capacity with 48x10GbE access ports plus 12x40GbE uplink ports, supporting 4x10GbE breakout on QSFP+ uplinks. The SwitchX-2 ASIC delivers sub-microsecond cut-through latency suitable for storage and HPC adjacency. The x86 quad-core CPU runs the full MLNX-OS feature set including L2/L3 routing, MLAG, OSPF, BGP, and VxLAN. Dual hot-swappable AC power supplies provide 1+1 redundancy. Connector-to-PSU airflow places the switch in cold-aisle facing port deployments. Standard 19-inch chassis depth.
Deployment & Use Cases
10GbE Top-of-Rack switch for compute and storage racks. Leaf node in two-tier leaf-spine fabric with 40GbE uplinks. Storage front-end aggregation for NFS, iSCSI, and SMB. Hyperconverged infrastructure underlay for VMware vSAN and Nutanix clusters. Edge aggregation for OpenStack Neutron deployments using VLAN or VxLAN.

Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox SFP+ DAC and AOC cables, standard SFP+ SR/LR transceivers, MC2207 and MC2210 QSFP+ DAC/AOC, and ConnectX-3/3 Pro/4 Lx EN/5 EN adapters. QSFP+ uplink ports support 4x10GbE breakout with appropriate breakout cables. Connector-to-PSU airflow is not interchangeable with PSU-to-Connector units in the same hot/cold aisle layout. This is an Ethernet-only switch and does not support InfiniBand. Some advanced MLNX-OS features (e.g., VxLAN routing) require licensed software packages.
