NVIDIA Mellanox MSX6012F-2BFS SwitchX-2 1U FDR InfiniBand Switch (NVIDIA P/N 920-9B010-00FF-0M0): This is a 12-port QSFP+ FDR InfiniBand 1U managed switch built on the SwitchX-2 ASIC. It is a managed top-of-rack/edge switch for FDR (56Gb/s) InfiniBand fabrics - it is NOT an EDR/HDR/NDR switch, and although the SwitchX-2 family supports VPI, this SKU is positioned as an InfiniBand switch. Condition: Refurbished and tested.
Engineering Context: Powered by the Mellanox SwitchX-2 InfiniBand silicon with a PPC460 management processor. The 12 QSFP+ ports operate at FDR (56Gb/s) per port and auto-negotiate down to QDR/DDR for legacy HCAs. Short-depth 1U chassis with connector-side airflow exhaust (port-to-PSU direction). Dual hot-swap AC power supplies provide N+N redundancy. RoHS6 compliant.
Deployment & Use Cases: Edge or aggregation switch for legacy FDR InfiniBand HPC clusters; storage-fabric switch for FDR-attached arrays; lab or test-bed FDR fabric for development and validation; cost-effective replacement for end-of-life FDR switching equipment in research, university and engineering computing environments.
Technical Specifications:

Model: MSX6012F-2BFS
NVIDIA P/N: 920-9B010-00FF-0M0
ASIC: Mellanox SwitchX-2
Management CPU: PPC460
Ports: 12 x QSFP+
Data rate: FDR InfiniBand, 56 Gb/s per port
Backwards compatibility: Auto-negotiates to QDR (40 Gb/s) and DDR (20 Gb/s) for legacy HCAs
Power supplies: 2 x hot-swap AC PSUs (redundant)
Airflow: Connector-side exhaust (port-to-PSU direction)
Form factor: 1U short depth, 19-inch rack
Compliance: RoHS6
Condition: Refurbished, tested
Brand: NVIDIA Mellanox

Compatibility & Constraints: Compatible with Mellanox FDR InfiniBand HCAs (ConnectX-3, ConnectX-3 Pro, and FDR-capable ConnectX-4) and FDR QSFP+ DAC/AOC cables and transceivers. Auto-negotiates down to QDR/DDR for legacy HCAs but does NOT support EDR (100Gb/s), HDR (200Gb/s), or NDR (400Gb/s) - those rates require Switch-IB-2, Quantum, or Quantum-2 switches respectively. Rail kit is not included; order separately. Verify airflow direction matches your hot/cold-aisle layout before deployment.
Why TES: T.E.S IT-SOLUTIONS supplies tested, refurbished Mellanox SwitchX-2 FDR switches with full visibility on condition and configuration. Handling time: 1-3 business days.
