NVIDIA Mellanox NPTNMNG-FS2F2 Neptune 36-Port QSFP FDR Managed InfiniBand Switch (1U): This is a 1U rack-mount managed FDR InfiniBand switch with 36 QSFP ports, dual AC power supplies, and port-to-connector (P2C) airflow. It is a top-of-rack class managed switch for InfiniBand fabrics, not an Ethernet switch. This is a refurbished unit.
Engineering Context
The NPTNMNG-FS2F2 (Neptune platform) provides 36 FDR (56Gb/s) InfiniBand ports in a single 1U chassis with non-blocking switching capacity at the FDR signaling rate. The switch is "managed", meaning it includes an onboard subnet manager interface and a management Ethernet port for fabric configuration, monitoring, and firmware updates. Dual hot-swappable AC power supplies provide redundancy for production fabrics. P2C airflow (front-to-back, port-side intake) matches the cold-aisle / hot-aisle convention used in most data centers.
Deployment & Use Cases
Top-of-Rack switching for FDR InfiniBand HPC clusters running MPI workloads. Storage-fabric backbone for Lustre, GPFS/Spectrum Scale, and FDR-attached parallel storage arrays. Edge-of-fabric aggregation in mid-size InfiniBand deployments where 36 ports per 1U is the target density. Lab and training-rack deployments that require a managed FDR switch with redundant power.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: NPTNMNG-FS2F2
Platform: Neptune
Product Type: Managed InfiniBand Switch
Ports: 36 x QSFP
Per-Port Data Rate: FDR 56Gb/s
Form Factor: 1U Rack Mount
Power: Dual AC Power Supplies
Airflow: P2C (Port-to-Connector, front-to-back)
Management: Managed (includes onboard management interface)
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Constraints
Compatible with Mellanox FDR-capable adapters such as ConnectX-3, ConnectX-3 Pro, and FDR-enabled HCAs. Pairs with Mellanox copper FDR DAC and FDR AOC cables, plus FDR QSFP+ optical transceivers. Not an Ethernet switch — does not run Ethernet protocols. Not interchangeable with EDR (100Gb/s) or HDR (200Gb/s) plant; FDR transceivers and FDR-rated cables are required. P2C airflow direction is fixed and must match the rack airflow scheme.
