MQM9790-NS2F – HDR 200Gb/s Modular InfiniBand Switch for High-Performance AI & HPC

The MQM9790-NS2F from NVIDIA (Mellanox InfiniBand family) is a director-class modular switch platform that our wholesale channel supplies to system integrators, data center builders, and IT procurement teams deploying large-scale HPC and AI interconnect fabrics. Units shipped from our warehouse are batch-matched: line-card population, firmware revision, and accessory sets are consistent within each procurement batch, which simplifies staging, configuration, and downstream resale for channel partners.

Stock is confirmed at time of order, and we support both single-unit pilot purchases and multi-unit rack-level rollouts. All units leave the facility with CE, FCC, and RoHS documentation available for export compliance review, and our operations team assists with customs paperwork for overseas delivery.

Reseller & Integrator Guidance

• Before quoting your end customer, confirm rack space, front-to-back airflow alignment with the hot/cold aisle layout, and adequate power/cooling provisioning — director-class chassis carry significant facility requirements.
• Verify HDR-capable adapters (HDR HCAs), QSFP56 cabling, and transceiver compatibility are included in your bill of materials so batch shipments arrive deployment-ready.
• In NVIDIA’s InfiniBand portfolio, this modular director platform sits above fixed-configuration switches, making it a strong upsell for integrators whose clients outgrow single-chassis fabrics.
• Export orders: confirm the exact part number (920-9B210-00FN-0D0), line-card population, and power cord region with your account manager before we commit to a delivery schedule.

Every unit is covered by our standard warranty with structured RMA handling — defective units are replaced or credited through a tracked RMA workflow to keep your project timelines intact.
