PCIe riser 3 cable routing

Use the section to understand the cable routing for the PCIe riser 3.

Note
  • Connections between connectors; 1↔1, 2↔2, 3↔3, ... n↔n
  • When routing the cables, ensure that all cables are routed appropriately through the cable guides.
  • A label on each cable indicates the connection source and destination. This information is in the format RY-X and P Z. Where Y indicates the PCIe riser number, X indicates the connector on the riser card, and Z indicates the connector on the system board assembly.
