PCIe riser B cable routing

Follow the instructions in this section to learn how to do cable routing for the PCIe riser B.

Note
  • When routing the cables, ensure that all cables are routed appropriately through the cable guides and cable clips.
  • A label on each signal 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.
This configuration supports the following PCIe risers:
  • x16/x8/x8 PCIe G4 Riser 2/A/B/C HHHL (installed in the riser B)
  • x16/x8/x8 PCIe G5 Riser 2/A/B/C HHHL (installed in the riser B)
