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:
With one processor
