5-3 Connecting Cables
Now that the processors are installed, the next step is to connect the
cables to the board. These include the data (ribbon) cables for the periph-
erals 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 motherboard connector locations noted) should be con-
nected. See the motherboard layout figure in this chapter for connector
locations.
! IDE Device Cables (J2A and J3A)
! Floppy Drive Cable (JP7)
! Ultra 160 LVD SCSI Cables (JA1 and JA2)
! Control Panel Cable (JF2, see next page)

Connecting Power Cables

The P4DPR-6GM+ has a 20-pin primary power supply connector designated
"ATX Power" for connection to the ATX power supply. Connect the
appropriate connector from the power supply to the "ATX Power"
connector to supply power to the motherboard. See the Connector
Definitions section in this chapter for power connector pin definitions.
