NVIDIA Mellanox MTEF-FANF-I P2C Airflow Fan Module for SN4600 Series: This is a hot-swappable fan tray for NVIDIA Mellanox SN4600-series 200GbE Spectrum-3 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 930-9NFAN-00IT-000. This is a refurbished unit.
Engineering Context
The MTEF-FANF-I 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-I 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 Mellanox Spectrum-3 SN4600-series Ethernet switches. Cold-spare stocking for AI/HPC clusters running 200GbE leaf-spine fabrics. Airflow conversion projects where a chassis is moved into a P2C aisle layout. Lab and integration test rigs running continuous thermal cycling.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MTEF-FANF-I
NVIDIA P/N: 930-9NFAN-00IT-000
Type: Hot-swappable fan module
Airflow Direction: P2C (Power-to-Connector, front-to-rear)
Form Factor: SN4600-series 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 SN4600-series Spectrum-3 200GbE Ethernet switches that accept P2C 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 FANR-series (C2P) variants or with FANF modules sized for QM8700/SN3700 (different slot dimensions). Not compatible with SN3700/SN3700C/QM8700 chassis.
