PCIe riser B cable routing

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

Note

  • Connections between connectors; 1↔1, 2↔2, 3↔3, ... n↔n

  • The Cable PN or FRU PN can be found on the label attached to the cable.

  • When routing the cables, make sure that all cables are routed appropriately through the corresponding 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.
