PCIe expansion node

Use this section to understand how to route cables for a PCIe expansion node.

Following are the cables that come with a PCIe expansion node:

Note: Make sure the following conditions are met before installing the rear riser cable cover.
  1. If the PCIe#2-B cable is connected to the rear riser assembly, make sure it is routed under the PCIe#1-A cable through the gap between the two front riser power connectors.

  2. If the PCIe#1-A cable is connected to the rear riser assembly, make sure it is routed above the PCIe#2-B cable through the gap between the two front riser power connectors.

  3. When both riser assemblies are installed, make sure the front riser auxiliary power cable is looped back into the gap between the two front riser power connectors, and routed above the PCIe#2-B cable.
