PCIe riser 3 cable routing
Follow the instructions in this section to learn how to do cable routing for the PCIe riser 3.
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.
Choose the routing plan according to the PCIe riser type.
- See Two-slot PCIe riser 3 cable routing for the following PCIe riser:
- x16/x16 PCIe G5 Riser 1/3 FHFL (installed in the riser 3)
- See Three-slot PCIe riser 3 cable routing for the following PCIe riser:
- x8/x16/x16 PCIe G4 Riser 1/3 FHFL (installed in the riser 3)
