The NVIDIA Mellanox MTF005004 is a leaf-side cooling chassis fan unit for high-port-count Mellanox modular director switches scaling up to 216 ports, often referenced under the ORCA548 platform name. This is NOT a generic rack fan and NOT a CPU fan; it is a chassis-specific fan tray engineered for the airflow envelope of large multi-blade InfiniBand directors. MPN: MTF005004. Condition: Refurbished, RPM-tested at T.E.S IT-SOLUTIONS.
Engineering context. A 216-port modular director dissipates significant heat across many switch blades and the spine fabric. The MTF005004 drives airflow on the leaf side of the chassis, complementing the spine-side fan trays to maintain a complete front-to-back thermal corridor. The unit is hot-pluggable, allowing online replacement during a fan failure. Fan trays are normally deployed in N+1 redundancy.
Deployment and use cases. Used to keep ORCA548-class directors within thermal envelope under sustained line-rate loads — HPC fabrics, multi-rack InfiniBand SAN backbones, AI training fabrics, EDA grid computing, and any deployment where an existing director chassis has lost a fan tray and needs hot-swap replacement without a maintenance window.
Technical specifications:
Model: MTF005004
Type: Leaf-side chassis fan unit
Mounting: Hot-swappable fan tray
Target chassis: Mellanox modular director scaling up to 216 ports (ORCA548-class)
Airflow direction: Front-to-back

Compatibility and constraints. Compatible with the modular director chassis the MTF005004 is rated for (ORCA548-class, up to 216 ports). NOT compatible with smaller modular chassis or fixed-form Mellanox switches. The leaf-side and spine-side fan slots are distinct — verify the chassis slot the MTF005004 is rated for before installation. Buyer is responsible for confirming the chassis revision and existing fan tray inventory.
