NVIDIA Mellanox MTEF-FANF-M P2C Fan Module for SN4700 / MSN4700 Spectrum-3: This is a hot-swappable replacement fan tray (cooling module) for the Mellanox SN4700 / MSN4700 Spectrum-3 200GbE Ethernet switch. Airflow direction is P2C (Power-to-Connector, from the PSU side toward the front network ports). This is a fan tray only, not a PSU, transceiver, or full chassis. NVIDIA P/N 930-9BFAN-00IX-000. This unit is refurbished and tested.
Engineering Context
The MTEF-FANF-M maintains the chassis thermal envelope by pulling cool air from the PSU side of the switch and exhausting it across the network port side. P2C is the airflow direction used when the cold aisle is at the rear of the rack. The fan tray is hot-swappable: a failed unit can be removed and replaced without bringing the switch offline, provided remaining fans can sustain temporary thermal load until replacement is complete.
Deployment & Use Cases
Replacement of a failed fan tray in an SN4700 / MSN4700 chassis serving as a 200GbE leaf or spine. Preventive maintenance during scheduled windows for high-uptime AI/HPC clusters. Spare stocking for fleets of Spectrum-3 switches. Rack environments configured with cold-aisle-rear / hot-aisle-front airflow that match the P2C direction.

Compatibility & Constraints
Validated only for the SN4700 / MSN4700 Spectrum-3 chassis. Not compatible with SN2100, SN2410, SN2700, SN3000-series, SN4410, SN4600, or earlier Spectrum / Spectrum-2 fan bays — they use different fan trays. Do not mix P2C and C2P fan modules in the same chassis; mixed airflow causes thermal imbalance and is not supported. Confirm the SN4700 chassis is configured for P2C airflow before installing.
