Chapter 5: Advanced Motherboard Setup
5-3 Connecting Cables
Now that the processors are installed, the next step is to connect the cables to the motherboard. These include the data (ribbon) cables for the peripherals and control panel and the power cables.
Connecting Data Cables
The cables used to transfer data from the peripheral devices have been carefully routed in preconfigured systems to prevent them from blocking the flow of cooling air that moves through the system from front to back. If you need to disconnect any of these cables, you should take care to reroute them as they were originally after reconnecting them (make sure the red wires connect to the pin 1 locations). If you are configuring the system, keep the airflow in mind when routing the cables.
The following data cables (with their motherboard connector locations noted) should be connected.
See the motherboard layout diagram in this chapter for connector locations.

Connecting the Control Panel
JF1 contains header pins for various front control panel connectors. See Figure
All JF1 wires have been bundled into single keyed ribbon cable to simplify their con- nection. Connect one end of this cable to JF1 and the other end to the Control Panel printed circuit board, located just behind the system status LEDs in the chassis.
See the Connector Definitions section in this chapter for details and pin descrip- tions of JF1.
