Internal cable routing
Some of the components in the server have internal cables and cable connectors.
To connect cables, observe the following guidelines: 
•  Power off 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.
