Cable routing for PCIe riser assemblies and hot-swap drives

See this topic to learn how to do cable routing for the PCIe riser assemblies and hot-swap drives.

Attention
For 300mm chassis, make sure to complete adapter cable routing before proceeding to riser cable routing (see Cable routing for GPU/FPGA adapter power).

Choose the routing plan from the following table according to the planned configuration.
