PCIe riser cable routing
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
Figure 1. PCIe riser cable routing – one processor
| From (system board) | To (PCIe riser) | Cable |
|---|---|---|
| 1 PCIe riser power connector | 1 Power connector | Power 2x8 to power 2x4 (290 mm) |
| 2a PCIe riser (1S) sideband connector | 2 PCIe riser wired cable (Slot 2) | MCIO x16 (270 mm) |
| 2b PCIe riser (1S) connector | MCIO x16 (780 mm) |
With two processors
Figure 2. PCIe riser cable routing – two processors
| From (system board) | To (PCIe riser) | Cable |
|---|---|---|
| 1 PCIe riser power connector | 1 Power connector | Power 2x8 to power 2x4 (290 mm) |
| 2 PCIe riser slot 1 connector (Gen4) | 2 PCIe riser wired cable (Slot 1) | MCIO x16 (360 mm) |
| 3 PCIe riser slot 2 connector (Gen5) | 3 PCIe riser wired cable (Slot 2) | MCIO x16 (260 mm) |
