Chapter 6. Internal cable routing

See this section to do cable routing for specific components.
To connect cables, observe the following guidelines:
• Turn 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.
• 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 assembly.
• Ensure that the relevant cables pass through the cable clips.
Note: Disengage all latches, release tabs, or locks on cable connectors when you disconnect cables from
the system board assembly. Failing to release them before removing the cables will damage the cable
sockets on the system board assembly, which are fragile. Any damage to the cable sockets might require
replacing the processor board or system I/O board.

Identifying connectors
