NVIDIA Mellanox MTEF-FANR-L 400G 1U Hot-Swap Fan Module (C2P Airflow): This is a hot-swappable fan module engineered for NVIDIA Mellanox 400G 1U switches. The MTEF-FANR-L (NVIDIA P/N 930-9BFAN-00JA-000) provides Connector-to-Power (C2P) airflow, drawing air from the port side and exhausting through the rear power side. This is a chassis cooling module, not a standalone rack fan. This is a refurbished unit.
Engineering Context
C2P airflow matches the front-to-back orientation expected by standard hot-aisle/cold-aisle data center deployments where ports face the cold aisle. The hot-swappable design allows replacement under load without powering down the switch, preserving data plane availability. The module is sized specifically for 1U 400G switch chassis and uses a dedicated mechanical/electrical interface unique to those chassis. RPM is managed by the switch thermal control plane.
Deployment & Use Cases
Replacement of failed fan modules in NVIDIA Mellanox 400G 1U switches. Maintaining airflow direction consistency in C2P-configured chassis. Operational sparing for AI/HPC fabric switches in continuous-duty environments. Live-replacement of fans in production clusters without a service window.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MTEF-FANR-L
Alternate P/N: 930-9BFAN-00JA-000
Form Factor: 1U fan module
Airflow Direction: C2P (Connector to Power)
Hot-Swap: Yes
Compatibility: NVIDIA Mellanox 400G 1U switches
Module Type: Field-replaceable cooling unit

Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible only with NVIDIA Mellanox 400G 1U switch chassis that accept this fan SKU. Do not mix C2P and P2C fan modules in the same switch — airflow direction must match across all cooling modules. Not compatible with 2U chassis, SN3000/SN4000 1U switches with different fan SKUs, or non-Mellanox switches. Verify by chassis P/N before installation.
