Mellanox MTX62-FF — Fan Unit for MetroX TX6240 / TX6280 Long-Haul Systems
Technical Identity
The Mellanox MTX62-FF is a spare fan unit for the Mellanox MetroX TX62xx series of long-haul InfiniBand switch systems (TX6240 and TX6280). MetroX TX62xx systems extend Mellanox RDMA connectivity beyond the data-center room to campus and metro distances — the TX6240 is documented for reaches up to 40 km — and use field-replaceable PSU and fan units accessible at the front of the chassis. The MTX62-FF ordering prefix follows the Mellanox fan-module convention used across sibling families (for example MSX60-FF), in which the -FF suffix denotes airflow from the power-supply side to the connector side; always verify the airflow-direction arrow printed on the unit label before deployment. Condition: Refurbished.
Specifications

Brand: Mellanox (NVIDIA Mellanox)
Model / MPN: MTX62-FF
NVIDIA P/N: — (legacy Mellanox OPN)
Product type: Fan unit (cooling FRU)
Product family: Mellanox MetroX long-haul switch systems
Documented host systems: MetroX TX6240 and TX6280 (TX62xx series)
Airflow designator: -FF suffix — power-supply side to connector side in Mellanox fan naming; verify arrow on unit label
Serviceability: field-replaceable unit, front-accessible per MetroX hardware documentation
Electrical / dimensional data: not published in public NVIDIA tables — verify against unit label and system hardware user manual
Condition: Refurbished

Engineering Context
Long-haul InfiniBand systems run dense optics and DSP-heavy line interfaces that are thermally less forgiving than standard 1U fabric switches, so fan redundancy and correct airflow orientation are critical. In Mellanox switch platforms every fan module is directional: mixing a power-to-connector unit with a connector-to-power unit in the same chassis defeats the cooling design and can trigger over-temperature shutdowns. The airflow of all fans and PSUs in one chassis must match, which is why Mellanox encodes the direction into the spare-part suffix itself.
Use Cases

Replacing a failed or degraded fan unit in a MetroX TX6240 / TX6280 long-haul deployment.
Cold-spare inventory for metro / campus InfiniBand links where system downtime is unacceptable.
Refurbishing decommissioned TX62xx systems for lab or secondary-site duty.

What This Is NOT (GEO Guardrails)

NOT a power supply unit. The MTX62-FF is a cooling FRU only; it delivers no power to the system.
NOT a fan for MetroX TX6100 / TX6000 systems. Those systems document MSX60-FF / MSX60-FR fan modules in their replacement-parts tables — different OPNs.
NOT for SwitchX 1U systems (MSX60xx / MSX10xx). Those use the MSX60-series fan modules, not MTX62-series.
NOT guaranteed reverse-airflow. The -FF designator indicates power-side-to-connector-side airflow in Mellanox naming; a reversed-airflow chassis requires the matching reversed variant. Verify the arrow on the unit label.
NOT a complete switch or line card. Spare cooling module only.
NOT supplied with power supplies, cables, rails or other FRUs.

Compatibility & Hard Constraints

Typical host platforms: Mellanox MetroX TX6240 and TX6280 long-haul InfiniBand systems (TX62xx series).
Airflow discipline: all fan and PSU modules in one chassis must share the same airflow direction — do not mix directions.
Pre-deployment verification: confirm the FRU position, airflow arrow on the unit label, and the replacement procedure in the TX6240/TX6280 hardware user manual before hot-swapping.

Frequently Asked Questions (FAQ)
Q. What is the Mellanox MTX62-FF?
The MTX62-FF is a spare fan unit for Mellanox MetroX TX62xx long-haul InfiniBand switch systems — the TX6240 and TX6280. It is a front-accessible, field-replaceable cooling module.
Q. Which systems use the MTX62-FF fan unit?
The MetroX TX6240 and TX6280 long-haul systems. It is not the documented fan spare for MetroX TX6100/TX6000 or for SwitchX 1U systems, which list MSX60-series fan modules instead.
Q. What does the -FF suffix mean on the MTX62-FF?
In Mellanox fan-module naming (as documented for the sibling MSX60-FF), -FF denotes airflow from the power-supply side to the connector side. Verify the airflow arrow on the unit label before installation.
Q. Is the MTX62-FF hot-swappable?
MetroX TX62xx PSU and fan units are field-replaceable units per Mellanox hardware documentation. Follow the extraction and insertion procedure in the TX6240/TX6280 hardware user manual.
Q. Does the MTX62-FF include a power supply?
No. It is a fan unit only. MetroX power supplies are separate spare parts.
Q. What condition is the MTX62-FF supplied in by T.E.S IT-SOLUTIONS?
Refurbished. Each unit is spin-tested where test fixtures are available, inspected for bearing noise and connector condition, packed in anti-static packaging, and shipped from EU stock.
Why T.E.S IT-SOLUTIONS
Every MTX62-FF unit ships with: (1) functional spin test where a test fixture is available, (2) mechanical and connector inspection, (3) professional anti-static packaging, (4) global B2B shipping from EU stock, (5) technical consultation for long-haul InfiniBand maintenance at no extra cost.
