The NVIDIA Mellanox® MTEF-FANF-E is a refurbished hot-swappable fan tray module with P2C (Power-to-Connector) airflow, designed as a field-replaceable cooling unit for the Mellanox SN2740 100GbE Spectrum switch. It is not a power supply, not a transceiver, and is not a drop-in for SN3700, SN4000, or QM-series switches — those chassis use different fan part numbers. Ships in Refurbished condition, functionally tested.
Engineering context. The MTEF-FANF-E is one of the fan tray slots in an SN2740 chassis, providing redundant cooling alongside the other fan trays. Airflow is unidirectional P2C, meaning air enters from the port (network) side and exits on the PSU side — the standard front-to-back airflow for cold-aisle/hot-aisle data centers. The fan tray is tool-less and can be removed and replaced while the switch remains powered, with brief loss of one fan zone tolerated by the chassis cooling envelope.
Deployment and use cases. Typical scenarios: replacing a failed fan tray in a production SN2740 to restore full redundancy without downtime, stocking field spares for 100GbE leaf or aggregation switches under maintenance contracts, and upgrading older fan trays in deployments that have logged high run-time hours. Suitable for enterprise data centers, colocation environments, and HPC labs running SN2740-based Ethernet fabrics.
Technical specifications.
- Part number: MTEF-FANF-E
- Type: Hot-swappable fan tray module
- Airflow direction: P2C (Power-to-Connector, front-to-back)
- Compatible chassis: NVIDIA Mellanox SN2740
- Installation: tool-less hot-swap
- Redundancy role: N+1 fan tray redundancy in SN2740
- Status indicator: per-tray LED
- Compliance: RoHS 6
- Condition: Refurbished, bench-tested for RPM stability and thermal output
Compatibility and constraints. The MTEF-FANF-E is qualified for the SN2740 chassis only. Mixing P2C and C2P fan trays in the same chassis is not supported — the chassis must run with a single, consistent airflow direction. This part is not interchangeable with MTEF-FANR-* (reverse / C2P) fans, nor with fan trays for the SN3700, SN4000, or Quantum (QM) families. Confirm chassis fan-direction polarity before ordering.
Why TES. T.E.S IT-SOLUTIONS is a B2B reseller of refurbished NVIDIA Mellanox enterprise networking hardware. Every fan tray is bench-tested for RPM stability, airflow direction, and LED status reporting before shipment. Orders are processed with 1–3 business day handling from Israel, professionally packed.
