NVIDIA Mellanox MTEF-FANR-I Hot-Swap Fan Module, C2P Airflow: This is a hot-swappable fan tray for NVIDIA Mellanox 1U switch chassis configured for C2P (Connector-to-Power) airflow. It is a field-replaceable cooling module, not a complete switch. C2P means air enters from the port side and exits through the PSU side. This is a refurbished unit, tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MTEF-FANR-I is part of the redundant cooling system for NVIDIA Mellanox 1U switches. Mellanox 1U chassis use multiple hot-swap fan trays so a single fan failure does not interrupt traffic. The chassis management firmware monitors RPM and raises an alarm on any fan that drops below threshold. The C2P airflow direction must match the airflow of every PSU and fan tray in the same chassis; mixed directions are not supported.
Deployment & Use Cases
Replacement fan tray for Mellanox 1U switches configured for C2P airflow, where the port side faces the cold aisle. Spare inventory for redundant cooling maintenance. Used in HPC fabric, AI training, and enterprise data center deployments where rack airflow conventions place ports on the cold-aisle side.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MTEF-FANR-I
Type: Hot-Swap Fan Module
Airflow: C2P (Connector-to-Power, port-to-power)
Form Factor: 1U Fan Tray
Application: Mellanox 1U Switch Cooling
Hot-Swap: Yes
Condition: Refurbished
Compatibility & Constraints
Compatible with NVIDIA Mellanox 1U switches that accept the MTEF-FANR series in C2P configuration. Must be installed only with matching C2P fan trays and C2P PSUs. Not compatible with P2C (reverse airflow) chassis configurations. Specific switch model fitment should be confirmed against the Mellanox parts compatibility matrix before deployment; do not assume cross-compatibility with the visually similar MTEF-FANF-F (which is P2C).
