5-2 Connecting Cables
Now that the motherboard is installed, the next step is to connect the cables to the
board. 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 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 keep them routed as they were originally after reconnecting
them. The following data cables (with their locations noted) should be connected.
(See the layout in Section 5-7 for connector locations.)
Important! Make sure the the cables do not come into contact with the fans.
Connecting Power Cables
The K1SPE has a 24-pin primary power supply connector (JPW1) for connection
to the ATX power supply. In addition, an 8-pin processor power connector (JPW2)
must also be connected to your power supply. See Section 5-8 for power connector
pin defi nitions.
Connecting the Control Panel
JF1 contains header pins for various front control panel connectors. See Figure 5-1
for the pin defi nition. All JF1 wires have been bundled into a single ribbon cable
to simplify this connection. Make sure the red wire plugs into pin 1 as marked on
the board.
