Chapter 3. Internal Cable Routing; Fan Power Cable - Lenovo ThinkSystem ST250 V2 Maintenance Manual

Chapter 3. Internal cable routing

Some of the components in the server come with internal cables meant for specific connectors.
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.
Notes:
1. Disengage all latches, release tabs, or locks on cable connectors when you disconnect cables from the
system board. Failing to release them before removing the cables will damage the cable sockets on the
system board, which are fragile. Any damage to the cable sockets might require replacing the system
board.
2. When installing the front system fan into the chassis, make sure the cables do not interfere with the two
posts and the fan is firmly seated.
