Important:
• Before you move any jumpers, power off the server; then, disconnect all power cords and external cables.
Do not open your server or attempt any repair before reading and understanding the following information:
– http://thinksystem.lenovofiles.com/help/topic/safety_documentation/pdf_files.html
– "Handling static-sensitive devices" on page 41
• Any system-board switch or jumper block that is not shown in the illustrations in this document are

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.
• 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 relevant cables pass through the cable clips.
