3.11 Cable Routing Diagrams
The below diagrams indicate the cable routing for the storage, PCIe, IO, and power cables.
When disconnecting cables to add or replace components, refer to the diagrams so you can
reroute them in the same manner. If cables are not connected or routed properly it may lead
to device detection or performance issues.
