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