NVIDIA Mellanox® 930-9SFAN-00RM-00B Fan Unit | C2P (Connector-to-Port) Airflow | Red Latch | Hot-Swap FRU Cooling Module for Spectrum-4 & Quantum-2 Switches
Product Description
The NVIDIA Mellanox® 930-9SFAN-00RM-00B is a high-performance Field Replaceable Fan Unit (FRU) designed for the latest generation of air-cooled NDR/XDR switches. This fan module provides the required C2P (Connector-to-Port) airflow, identified by its Red Latch, ensuring correct thermal alignment in rear-intake / front-exhaust data-center designs.
Engineered for Spectrum-4 Ethernet (SN5400/SN5600 series) and Quantum-2 InfiniBand (QM9700/QM9790) switches, this cooling module maintains the strict thermal envelope required for dense 400Gb/s and 800Gb/s (NDR/XDR) fabrics used in AI training clusters, cloud infrastructure, and hyperscale data centers.
Its hot-swappable construction allows technicians to replace the fan without shutting down the switch — ensuring uninterrupted availability for mission-critical workloads.
Key Features
Optimized C2P Airflow – Red Latch Direction Indicator
Air Intake: Rear / Connector Side (Cold Aisle)
Air Exhaust: Front / Port Side (Hot Aisle)
Red Latch: Confirms airflow direction to prevent mismatched installation.
Ensures correct thermal behavior in standardized hot-aisle/cold-aisle environments.
Designed for Next-Generation NDR/XDR Platforms
Validated for:
Spectrum-4 Ethernet Switches: SN5400, SN5600
Quantum-2 InfiniBand Switches: QM9700, QM9790
High-density 400G/800G chassis requiring controlled rear-to-front cooling.
Not compatible with HDR (e.g., QM8700), preventing customer mismatch.
High Static Pressure Cooling for 400G/800G Transceivers
The impeller design pushes concentrated airflow through:
OSFP cages
QSFP-DD heatsinks
High-power switch ASIC cooling chambers
Ensures stable operation even under heavy AI workloads.
Hot-Swappable FRU Module
Replaceable during full switch operation
Zero downtime
Safe servicing in production AI clusters or dc fabric roles
Smart PWM Control
Integrates with switch firmware (MLNX-OS / Cumulus) to:
Adjust fan RPM based on ASIC temperature
Reduce noise & power consumption
Maintain longevity of switch components
