Identity & Definition
This enterprise Ethernet data center switch, the NVIDIA Mellanox MSX1400-BS2F2, is a 1U fixed-configuration SwitchX-2 Open Ethernet switch with 48x SFP+ (10GbE) ports and 12x QSFP+ (40GbE) ports, running MLNX-OS. The switch ships with dual AC power supplies and Power-to-Connector (P2C) airflow. This is an Ethernet-only switch — it does not support InfiniBand. Condition: NEW.
Engineering Context
The MSX1400-BS2F2 delivers 1.56 Tb/s aggregate switching capacity via the SwitchX-2 ASIC with non-blocking, cut-through forwarding at sub-microsecond port-to-port latency. The 48 SFP+ ports serve server connections at 10GbE, while the 12 QSFP+ ports provide 40GbE uplinks to spine switches or aggregation layers. MLNX-OS supports L2/L3 switching, MLAG, VXLAN, and OpenFlow for SDN environments. The x86 quad-core management CPU enables on-switch automation and monitoring.
Deployment & Use Cases
Top-of-rack switching for 10GbE server farms with 40GbE spine uplinks in leaf-spine Ethernet fabrics. Aggregation layer in enterprise data centers connecting multiple server racks. SDN deployments using OpenFlow and MLNX-OS programmability. Mixed 10G/40G environments requiring a single unified switch for VMware ESXi, KVM, or bare-metal hosts.

Compatibility & Hard Constraints
Ethernet Only: This is an Ethernet switch. It does not support InfiniBand. P2C Airflow: Power-to-Connector cooling direction. Verify this matches your rack airflow before installation. Reverse airflow (C2P) requires a different SKU. SFP+ Ports: Accept SFP+ (10GbE) transceivers and DAC cables only. Do not insert SFP28 modules expecting 25GbE — these ports are 10GbE maximum. QSFP+ Ports: Accept QSFP+ (40GbE) transceivers and DAC cables only. Not compatible with QSFP28 or QSFP-DD at higher speeds. MLNX-OS Only: This switch runs Mellanox's proprietary NOS. It does not support Cumulus Linux, SONiC, or ONIE without hardware/firmware verification. Predecessor: SwitchX (MSX1012 series). Successor: Spectrum (SN2100/SN2700 series).
