NVIDIA Mellanox® 930-9SPSU-00RA-00A — 2000W AC PSU (C2P Airflow) for MSN5610 Spectrum Switch

Technical Identity
The NVIDIA Mellanox® 930-9SPSU-00RA-00A is a 2000W (2 kW) AC hot-swap power supply unit with C2P (Connector-to-Power) airflow, factory-matched to the NVIDIA Spectrum™ MSN5610-series Ethernet switch platform. The C2P airflow direction draws cool air from the port / connector side of the chassis and exhausts heated air through the PSU rear — the correct orientation for racks where switch ports face the cold aisle. Supplied by T.E.S IT-SOLUTIONS in Refurbished Grade A condition, each PSU is bench-tested for AC input range, output rails, fan rotation, and PMBus telemetry response before shipment.

What This Is NOT

NOT a complete switch. This is a replacement / spare AC PSU module only — the MSN5610 chassis, fans, and management board are sold separately.
NOT a DC PSU. This SKU is the AC-input variant; DC-input PSUs carry a different NVIDIA P/N.
NOT P2C airflow. Do not mix C2P and P2C PSUs in the same chassis — the PSU airflow direction must match the installed fan modules.
NOT bundled with AC power cords, rail kits, or fan modules — those are separate NVIDIA part numbers.


Compatibility & Constraints

Host switch: NVIDIA Spectrum™ MSN5610-series Ethernet switch — verify the exact dash-code variant of your chassis before installation.
Airflow matching: All PSUs and fan modules installed in a single chassis must share the same airflow direction (C2P here). Mixing C2P and P2C units triggers thermal alarms and may shut the switch down.
Redundancy: The MSN5610 platform uses dual hot-swap PSUs in 1 + 1 redundancy — install a matched pair of 930-9SPSU-00RA-00A units for full redundancy.
Power cords: Sold separately. Confirm the chassis AC inlet type (C13/C14 or C19/C20) and rack PDU outlet before ordering.
Firmware / SDK: No PSU-side firmware update is required for a refurbished swap; the switch CPU recognises the PSU automatically via PMBus on insertion.


Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox 930-9SPSU-00RA-00A?
The 930-9SPSU-00RA-00A is a 2000 W AC hot-swap power supply unit with C2P (Connector-to-Power) airflow, designed for the NVIDIA Spectrum MSN5610-series Ethernet switch.
Q. What does C2P airflow mean and why does it matter?
C2P stands for Connector-to-Power: cool air is drawn in from the port / connector side of the switch and exhausted out through the PSU side. This is the correct airflow direction when switch ports face the cold aisle of the rack. All PSUs and fans inside a single chassis must share the same airflow direction — never mix C2P with P2C units.
Q. Can I mix this PSU with a P2C (reverse-airflow) PSU in the same switch?
No. Mixing C2P and P2C modules in a single chassis triggers thermal alarms and can cause the switch to shut down. Order matched PSUs (and matching fan modules) for any installation.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished Grade A. Each unit is bench-tested by T.E.S IT-SOLUTIONS: AC input range check, output rail verification, fan-rotation test, PMBus telemetry response, and full cosmetic inspection. Ships from EU stock in professional anti-static packaging with worldwide B2B express options.

Why buy from T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS is a Europe-based NVIDIA Mellanox specialist serving HPC, AI, and enterprise data-center procurement since 2007. Every PSU is identified by exact NVIDIA P/N (930-9SPSU-00RA-00A), airflow direction (C2P), and target chassis (MSN5610) before it ships — so you never end up with the wrong airflow or a mismatched chassis revision. Multi-currency B2B invoicing, EU stock with worldwide express options, and direct technical contact with our networking engineering team — not a call-center.
