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 cables used to transfer data from the peripheral devices have been carefully
routed in preconfi gured systems to prevent them from blocking the fl ow 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 confi guring the system, keep the airfl ow in mind when routing the cables.
The following data cables (with their serverboard connector locations noted) should
be connected. See the serverboard layout diagram in this chapter for connector
locations.
DVD-ROM Drive cable (IDE)
Control Panel cable (JF1, see next page)
SATA cables (SATA0 ~ SATA3)
Connecting Power Cables
The X7DCU has a 20-pin primary power supply connector designated "JPW1" for
connection to the ATX power supply. Connect the appropriate connector from the
power supply to JPW1 to supply power to the serverboard. See the Connector
Defi nitions section in this chapter for power connector pin defi nitions.
In addition, your power supply must be connected to the 4-pin Auxiliary ATX Power
connection at JPW2 and the 8-pin Processor Power connector at JPW3.
Connecting the Control Panel
JF1 contains header pins for various front control panel connectors. See Figure
5-1 for the pin locations of the various front control panel buttons and LED indica-
tors. Please note that even and odd numbered pins are on opposite sides of each
header.
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
