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 precongured systems to prevent them from blocking the 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 conguring the system, keep the air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 (USB header 4)
•SATA cables (SATA0 ~ SATA3)
•Control Panel cable (JF1, see next page)

Connecting Power Cables

The H8DGU-F has a 20-pin primary power s upply connector designated "JPW1"
for connection to the ATX power supply. Connect th e appropriate connector from
the power supply to JPW1 to supply power to the ser verboard. See the Connector
Denitions section in this chapter for power connecto r pin denitions.
In addition, your power supply must be connected to the 8-pin Processor Power
connectors at JPW2 and 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
other end of the cable to the Control Panel printed circuit board, located just behind
the system status LEDs in the chassis.
