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 (wit h their serverboard conn ector locations noted)
should be connected.
See the serverboard layout diagr am in this chapter for connector loc ations.
DVD-ROM Drive cable (IDE#1)
Control Panel cable (JF1, see next page)
SATA cables, 6015W-NTR/6015W-NT only (I-SATA0 ~ I-SATA3)
SGPIO cable, 6015W-NTR/6015W-NT only (T-SGPIO1 to SATA backplane)

Connecting Power Cables

The X7DWU has a 20-pin primar y 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 co nnector 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.
