What Is Factory Acceptance Test?_
The FAT is a structured procedure where the vendor demonstrates that the equipment—such as a GPU server, liquid cooling distribution unit, or network switch—operates correctly under simulated load and environmental conditions. It typically includes functional checks, stress testing, and validation of alarms and safety interlocks. Passing the FAT is a prerequisite for shipment to the deployment site, reducing the risk of on-site failures.
Technical Details
For GPU systems like the H100 or GB200 NVL72, the FAT may involve running a standardized compute benchmark and verifying NVLink connectivity between GPUs within a rack. Liquid cooling loops are pressure-tested and flow-checked per the OEM specification. The test also confirms that all management interfaces (e.g., BMC, switch CLI) respond correctly, and that firmware versions match the bill of materials.
How Leviathan Systems Works with Factory Acceptance Test
In our field work, the FAT report is reviewed by the Leviathan commissioning lead before the equipment leaves the factory, as it determines whether we proceed with rack assembly and structured cabling at the data center. A failed FAT can delay deployment by weeks, so we coordinate closely with the vendor's test engineers to resolve any anomalies.
