NVIDIA L40S 48 GB PCIe accelerator
NVIDIA Ada Lovelace; AD102 GPU. This record describes the specified PCIe product configuration, not every OEM implementation.
MODEL IDENTIFICATION: L40S is distinct from L40: different power/performance configuration and intended workloads; do not transfer L40 I/O assumptions. Match the board label, part number and revision before applying reference specifications.

Compatibility and installation caveats
Install only in a server validated for the 350 W board and its 16-pin power lead; follow NVIDIA/OEM cable and airflow requirements. Passive cooling requires server-class directed airflow. Select supported NVIDIA data-center drivers and validate OS, CUDA and virtualization software versions against the platform qualification matrix. PCIe link generation is platform-negotiated.
- Check the exact card manual and server qualification list for slot, power pinout, chassis clearance, airflow and firmware support before installation.
- Preserve the driver and firmware source/version used for evaluation; do not assume consumer GeForce software or an unqualified workstation supports data-center features.
- Power only a board with undamaged connectors and verified supply/cable pinout; record condition before bench testing.
