NVIDIA Mellanox MTEF-FANF-C P2C Airflow Fan Module: This is a hot-swappable fan tray for NVIDIA Mellanox 1U switch chassis. The "FANF" designator indicates Power-to-Connector (P2C, front-to-rear) airflow direction. This is a chassis fan module, not a PSU fan or external rack fan. NVIDIA P/N 930-9BFAN-00IN-000. This is a refurbished unit.
Engineering Context
The MTEF-FANF-C exhausts air from the cold aisle (port side) toward the hot aisle (connector side), which is the standard P2C convention. Hot-swap insertion allows fan replacement under load without bringing the switch offline. Multiple FANF modules are populated per chassis to provide N+1 cooling redundancy, and switch firmware monitors per-module RPM and tach signals to flag a degraded unit before thermal shutdown thresholds are reached.
Deployment & Use Cases
Field replacement of failed fan trays in NVIDIA Quantum InfiniBand and Spectrum Ethernet 1U chassis. Cold-spare stocking for HPC and AI clusters where switch uptime is critical. Airflow conversion projects when a chassis is moved from a C2P aisle layout into a standard P2C aisle layout. Lab and integration test rigs running 24/7 thermal cycling.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MTEF-FANF-C
NVIDIA P/N: 930-9BFAN-00IN-000
Type: Hot-swappable fan module
Airflow Direction: P2C (Power-to-Connector, front-to-rear)
Form Factor: 1U chassis fan tray
Hot-Swap: Yes
Status Monitoring: RPM/tach reported to switch firmware
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox QM8700 InfiniBand HDR switches and SN3700/SN3700C/SN4700 Spectrum Ethernet switches that accept P2C 1U 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 the MTEF-FANR-C (C2P) variant. Not compatible with 2U Spectrum chassis or modular SN/QM systems with different fan slot dimensions.
Why Choose T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS bench-tests every fan module for RPM stability, tach signal, and connector seating before shipment. Orders ship in 1–3 business days with global delivery, and our team can advise on airflow matching and supported chassis revisions.
