The NVIDIA Mellanox® MTEF-FANF-L (NVIDIA P/N: 930-9BFAN-00IW-000) is a hot-swappable fan tray FRU for NVIDIA Mellanox 1U high-speed switch chassis. This is a chassis-level cooling module — not a system-level air handler, blanking panel, or 2U fan unit. Condition: Refurbished — tested for fan RPM, tachometer signaling, and thermal envelope before dispatch.
Engineering Context. The MTEF-FANF-L delivers P2C (power-to-connector / front-to-rear) airflow, drawing intake air across the PSU bay and exhausting heat past the port cage — the standard direction for hot-aisle/cold-aisle data centers where switch front-faces sit on the cold aisle. The module integrates fan tachometer feedback so the host switch BMC can monitor RPM and raise SNMP traps on speed degradation. Hot-swap operation lets you replace a single fan without taking the switch offline; remaining fans cover thermal load through the swap window.
Deployment & Use Cases. Field replacement unit for thermal events on Mellanox 1U switch and gateway platforms running 100GbE/200GbE/400GbE workloads — top-of-rack leaves for AI training clusters, NVMe-oF storage spines, EVPN-VXLAN data center fabrics, and HPC interconnect fabrics. Also stocked as proactive spares on edge sites with limited remote-hands windows.

Compatibility & Constraints. Compatible with NVIDIA Mellanox 1U switch chassis specified for P2C airflow keying. Do not mix P2C and C2P fans in the same chassis — opposing airflow induces back-pressure, hot-spotting, and thermal-shutdown alarms. Always match airflow direction across all fan trays and PSUs in a single system. Verify the exact airflow color and chassis fan-bay P/N against the host platform documentation before install. Not compatible with C2P (reverse-airflow) chassis or with 2U fan units.
