NVIDIA Mellanox MSX6036F-1SFR SwitchX FDR InfiniBand Managed Switch, 36 QSFP Ports, 1U: This is a 1U 36-port QSFP managed InfiniBand switch built on the SwitchX silicon platform, supporting non-blocking FDR (56Gb/s) port speeds. The 1SFR suffix indicates one power supply, managed (S), standard depth (F), and reverse airflow (R, PSU side to connector side). This is a managed switch with the embedded Mellanox switch OS for subnet management. This is a refurbished unit.
Engineering Context
The MSX6036F provides full bisectional bandwidth across all 36 ports for a total switching capacity of 4.032Tb/s. Per-port latency is in the low-hundreds of nanoseconds, typical of single-chip FDR switches. The managed variant runs the embedded MLNX-OS subnet manager (SM), so no external SM host is required for small-to-medium fabrics. Power draw is on the order of ~120W typical for a single PSU configuration. Standard 19" depth allows mounting in conventional server racks.
Deployment & Use Cases
Top-of-Rack InfiniBand aggregation in HPC clusters. Standalone subnet manager for small-to-medium fabrics that do not require an external opensm host. Storage interconnects for parallel filesystems (Lustre, GPFS) running over IB FDR. Lab and pre-production fabric testing where a single managed switch can run the full subnet on its own.

Compatibility & Hard Constraints
Compatible with Mellanox QSFP DAC, AOC, and FDR optical transceivers. Pairs with ConnectX-3, ConnectX-3 Pro, and ConnectX-4 IB HCAs. Single PSU configuration: there is no internal redundancy — for redundant power, source a 2-PSU model (MSX6036F-2SFR) or deploy a separate UPS. Reverse airflow direction (PSU-to-connector) must match the rest of your hot/cold aisle layout — do not mix airflow directions in the same enclosure. Not Ethernet-capable in this SKU; this is an InfiniBand-only switch.
