PCIe Interface

The HL-325L is an OCP OAM spec V2.0 compliant card. The HL-325L accelerator card utilizes the x16 Gen5 PCIe link.

PCIe Device ID:

  • Device ID: 0x1060

  • Vendor ID: 0x1DA3

  • Sub-System Device ID: 0x1060

  • Sub-System Vendor ID: 0x1DA3

  • Class Code: 12h (Processing Accelerator)

PCIe Failover Behavior

Several lanes are detected and supported at larger lane counts. The system falls back to lower speeds if the link training fails, starting at 16 lanes and gradually decreasing to 1 lane (16 → 8 → 4 → 2 → 1).
