5-3 Connecting Cables
Now that the processors and heatsinks are installed, the next step is to
connect the cables to the serverboard and install memory. Cables 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 system
yourself, 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. See Section 5-8 for data cable pin definitions.

Connecting Power Cables
The P4QH8/P4QH6 has a 24-pin primary power supply connector desig-
nated "ATX Power" for connection to the ATX power supply. There are
also 8-pin and 4-pin power connectors which must be connected to your
power supply. See Section 5-8 for power connector pin definitions.
