Follow instructions in this section to route the cables for the PCIe riser.

Note
  • Depending on the specific configuration, the information in this topic might not apply to your node.
  • Connections between connectors; 1↔1, 2↔2, 3↔3, ... n↔n
  • When routing the cables, make sure that all cables are routed appropriately through the corresponding cable guides and cable clips.
The PCIe riser cable routing contains the following configurations:
