Internal cable routing
Some of the components in the server have internal cables and cable connectors.
Some options, such as RAID controllers, might require additional internal cabling. See the documentation that is provided for the option to determine any additional cabling requirements and instructions.
Make sure that all the cables go through the cable guides, as shown in each cabling section.
Disconnect all power cords from the server before you connect or disconnect any internal cables.
See the documentation that comes with any external devices for additional cabling instructions. It might be easier for you to route cables before you connect the devices to the server.
Cable identifiers of some cables are printed on the cables that come with the server and optional devices. Use these identifiers to connect the cables to the correct connectors.
Ensure that the cable is not pinched and does not cover any connectors or obstruct any components on the system board.
Ensure that the relevant cables pass through the cable clips.
