NVIDIA Mellanox MTEF-PSR-AC-F 1500W AC Hot-Swappable Power Supply (C2P Airflow): This is a 1500-watt AC input, hot-swappable power supply unit (PSU) module designed for select Mellanox Spectrum Ethernet switch chassis. Airflow is C2P (Connector-to-Power, also called front-to-back from the port side). This is a redundant PSU module, not a switch, fan tray, or rail kit. NVIDIA P/N 930-9NPSU-00JJ-000. This unit is refurbished and tested.
Engineering Context
The MTEF-PSR-AC-F provides 1500 W of DC output to the switch internal power bus from a wide-range AC input. C2P airflow means cooling air enters at the network port side and exhausts toward the PSU/connector side, the orientation required when the switch is installed with cold aisle at the front of the rack. The module is hot-swappable, so a failed PSU can be replaced in a 1+1 redundant pair without dropping the data plane.
Deployment & Use Cases
1+1 redundant PSU configuration on MSN3930, MSN4600, and MSN4700 Spectrum switches in production data centers. PSU replacement during preventive maintenance windows. Spare stocking for AI/HPC fabrics where Spectrum switches host 100/200/400GbE leaf or spine roles. Cold-aisle-front rack deployments requiring C2P airflow.

Compatibility & Constraints
Validated for MSN3930, MSN4600, and MSN4700 chassis that accept the MTEF-PSR-AC-F module. Not compatible with switches that require the P2C (reverse) airflow PSU variant — using the wrong airflow direction creates thermal imbalance and is not supported. Not a DC PSU; AC input only. Do not mix C2P and P2C PSU variants in the same chassis. Confirm the chassis PSU bay accepts this part number before ordering.
