NVIDIA Mellanox MTEF-FANF-G P2C Airflow Fan Module with Shutters for SN4600C: This is a hot-swappable fan tray with integrated airflow shutters for the NVIDIA Mellanox SN4600C 200GbE Spectrum-3 switch. The "FANF" designator indicates Power-to-Connector (P2C, front-to-rear) airflow direction. The shutters automatically close when a tray is removed to maintain chassis pressure during hot-swap. This is a chassis fan module, not a PSU fan or external rack fan. This is a refurbished unit.
Engineering Context
The MTEF-FANF-G exhausts air from the cold aisle (port side) toward the hot aisle (connector side), the standard P2C convention. The integrated shutter mechanism prevents air-bypass during a single-tray removal so neighboring fans continue to draw the correct pressure differential across the ASIC heatsink. Hot-swap insertion allows fan replacement under load without bringing the switch offline. Switch firmware monitors per-module RPM and tach signals and will pre-emptively raise alarms before thermal shutdown thresholds are reached.
Deployment & Use Cases
Field replacement of failed fan trays in NVIDIA Mellanox SN4600C Spectrum-3 200GbE Ethernet switches. Cold-spare stocking for AI/HPC clusters and cloud leaf-spine fabrics. Chassis where shuttered fan trays are mandatory for compliance with airflow-pressure SLAs. Lab and integration test rigs running continuous thermal cycling.
Technical Specifications

Compatibility & Hard Constraints
Compatible with the NVIDIA Mellanox SN4600C Spectrum-3 200GbE Ethernet switch chassis that accepts P2C shuttered fan trays. All fan modules and PSUs in the same chassis must share the same airflow direction; mixing P2C with C2P inside one switch is not supported. Not interchangeable with FANR-series (C2P) variants or with non-shuttered FANF modules sized for QM8700/SN3700. Not compatible with QM8700/SN3700/SN3700C chassis.
