NVIDIA Mellanox MTEF-FANF-A Hot-Swap Fan Module, P2C Airflow: This is a hot-swappable replacement fan tray (NVIDIA P/N 930-9BFAN-00IJ-000) used in 1U Mellanox InfiniBand and Ethernet switch chassis. Airflow direction is P2C (Power-side to Connector-side, equivalent to rear-to-front when the PSU is at the rear). This is a field-replaceable fan unit, not a complete cooling kit and not a switch chassis. This is a refurbished unit.
Engineering Context
The MTEF-FANF-A is a single fan-tray module that slots into the rear bay of compatible Mellanox 1U switches. P2C airflow is required when the switch is mounted with its port side at the cold aisle and its PSU side at the hot aisle. Mixing P2C and C2P fans in the same chassis is not supported and will trigger thermal alarms. The unit is hot-swappable, meaning it can be replaced without powering down the switch, provided the remaining fans are operational. Status is reported via the chassis management interface.
Deployment & Use Cases
Spare-part replacement for failed fan trays in Mellanox MSX6710, MSB7700, MSX17xx, MSX67xx, and MSX6720 switch chassis. Stocking inventory for production InfiniBand FDR/EDR or 40/56GbE Ethernet fabrics. Maintaining N+1 cooling redundancy in 1U switch deployments. Restoring chassis to a single-airflow-direction state after partial fan failure.

Compatibility & Hard Constraints
Compatible only with Mellanox switch chassis that are designated for P2C airflow modules. The unit will not function in a chassis configured for C2P (Connector-to-Power) airflow, and mixing airflow directions across fan bays is prohibited. Not interchangeable with newer Quantum or Spectrum-series fan modules (different mechanical and electrical interfaces). Verify the host chassis service guide before fitting.
