5-3 Connecting Cables
Now that the processors are installed, the next step is to connect the
cables to the serverboard. These include the data (ribbon) cables for the
peripherals and control panel and the power cables.
Connecting Data Cables
The ribbon cables used to transfer data from the peripheral devices have
been carefully routed in preconfigured systems to prevent them from block-
ing 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 keep
them routed as they were originally after reconnecting them (make sure the
red wires connect to the pin 1 locations). If you are configuring the sys-
tem, keep the airflow in mind when routing the cables.
The following data cables (with their serverboard connector locations noted)
should be connected. See the serverboard layout figure in this chapter for
connector locations.

Connecting Power Cables
The X6DH8-G2/X6DH8-XG2 has a 24-pin primary power supply connector
designated JPW1 for connection to the ATX power supply. Connect the
appropriate connector from the power supply to the JPW1 connector to
supply power to the serverboard. The 12V 8-pin processor power connec-
tor at JPW3 and the 12V 4-pin power connector at JPW2 must also both be
connected to your power supply. See the Connector Definitions section in
this chapter for power connector pin definitions.
