Internal cable routing

Some of the components in the server come with internal cables meant for specific connectors.
Cable routing guidelines
Before connecting the cables, read the following guidelines carefully:
• Turn off the server before you connect or disconnect any internal cables.
• Refer to the documentation that comes with any external devices for additional cabling instructions.
• Make use of the identifiers printed on the cables to locate the proper connectors.
• Ensure that the cable is not pinched and does not cover any connectors or obstruct any components on
the system board.
