Description

NVIDIA Mellanox MTDF-PS-A 2500W AC Power Supply, 48VDC Output, P2C Airflow: This is a hot-swappable, high-capacity AC power supply (NVIDIA P/N 920-9IPN0-0000-031) for NVIDIA Mellanox CS7500 modular switch chassis and SN2000 series (Spectrum-2) systems. It delivers 2500W of AC-input power with a 48VDC output rail and P2C (Power-to-Connector) airflow. This is a field-replaceable PSU module, not a complete switch. This is a refurbished unit, tested by T.E.S IT-SOLUTIONS.

Engineering Context

The MTDF-PS-A is sized for the Mellanox CS7500 InfiniBand director chassis and Spectrum-2 SN2000 series, both of which use 48VDC backplane power and accept multiple PSU modules for N+N redundancy. The 2500W rating supports fully populated line-card chassis under sustained load. The P2C airflow direction must match every other PSU and fan module installed in the chassis; mixing airflow directions is not supported and will be flagged by chassis management.

Deployment & Use Cases

Replacement PSU for production Mellanox CS7500 InfiniBand director chassis and SN2000 Spectrum-2 spine switches. Spare inventory for N+N redundancy maintenance. Lifecycle replacement for switches with PSUs at end of warranty. Used in large-scale AI training fabrics, HPC clusters, and hyperscale data center spine layers.

Compatibility & Constraints

Listed for NVIDIA Mellanox CS7500 modular chassis and SN2000 series (Spectrum-2) configured for P2C airflow. Requires the chassis to accept the MTDF-PS series; this is not a generic 48V PSU. Not compatible with C2P airflow chassis configurations. Not interchangeable with the smaller MTEF-PSR or MTEF-PSF series. Always confirm the target chassis revision against the Mellanox compatibility matrix before swapping.
