Description
The NVIDIA Mellanox® MTEF-PSR-AC-K (NVIDIA P/N: 930-9NPSU-00JN-000) is a 2000W hot-swappable AC power supply unit (FRU) for NVIDIA Mellanox NVLink switch chassis. This is a chassis power module — not a rack-level PDU, line-conditioning UPS, or DC-input variant. Condition: Refurbished — tested for output rail regulation, hot-plug behaviour, and PMBus telemetry before dispatch.
Engineering Context. The PSU delivers up to 2000W AC output with C2P (connector-to-power / rear-to-front) airflow, intaking through the port side and exhausting past the PSU rear — the matched direction for chassis specified with reverse airflow. Internal fan speed and rail voltages report through the host BMC over PMBus, allowing supervision systems to alarm on rail droop, fan failure, or thermal margin loss before a hard fault. Hot-plug operation supports N+N redundancy: a single PSU swap can be performed without taking the switch out of service when paired with a redundant PSU.
Deployment & Use Cases. Field replacement and proactive spare for NVIDIA Mellanox NVLink switch chassis powering AI training pods, HGX/DGX-class GPU clusters, and large-scale HPC interconnect fabrics where uninterrupted multi-kilowatt power delivery is required during PSU service events.

Compatibility & Constraints. Designed for NVIDIA Mellanox NVLink switch chassis specified for the C2P airflow keying. Must match airflow direction with all other PSUs and fan trays in the same chassis — installing a C2P PSU into a P2C-keyed chassis (or vice-versa) causes back-pressure, hot-spots, and shutdown alarms. Verify the chassis fan/PSU bay color and exact PSU P/N against the host platform documentation before installing. Not compatible with DC-input chassis or with platforms requiring P2C airflow.
Frequently Asked Questions (FAQ)
Q. What is the MTEF-PSR-AC-K?
The MTEF-PSR-AC-K is a 2000W AC hot-swap power supply with C2P airflow for NVIDIA Mellanox switch systems.
Q. Can it be installed in a P2C-cooled chassis?
No. C2P and P2C power supplies are not interchangeable.
Q. Will T.E.S IT-SOLUTIONS confirm the fitment of MTEF-PSR-AC-K before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit before dispatch from EU stock.
Why TES. T.E.S IT-SOLUTIONS stocks NVIDIA Mellanox FRUs — PSUs, fan modules, rail kits, optical and copper cables — for current and end-of-life Spectrum, Quantum, and NVLink platforms. Orders ship from EU stock with 1-3 business day handling and pre-dispatch functional testing.
