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 and be aware of the pin 1 locations. If you are configuring the
system, keep the airflow in mind when routing the cables.
Connecting Power Cables
The motherboard has two 50-pin primary power supply connectors designated
JPW1 and JPW2. Connect the appropriate cable connectors from the power supply
to JPW1 and JPW2 to provide power to the motherboard.
Connecting the Control Panel
JF1 contains header pins for the front control panel connectors. All JF1 wires have
been bundled into single keyed ribbon cable to simplify their connection. The red
wire in the ribbon cable plugs into pin 1 of JF1. Connect the other end of the cable
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 descriptions
of JF1.
