Compatibility, service & archival notes
40 GB PCIe version has lower bandwidth/power characteristics than SXM A100; capacity is not pooled across GPUs.
Confirm exact 40 GB PCIe part and host firmware; provide validated server airflow and power budget. Record ECC, MIG mode, firmware and driver/CUDA versions before service.
- Check signaling, slot keying, lane width, power pinout, board/module dimensions, case clearance, airflow and PSU requirements for the exact specimen.
- Use drivers supporting its device ID and target OS. Preserve original installer and firmware copies, and record their versions before changes.
- Do not energize boards with corrosion, cracks, damaged connectors, obstructed cooling or suspected shorts; document condition before bench testing.
