5-3 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 ribbon cables used to transfer data from the peripheral devices have
been carefully routed to prevent them from blocking the flow of cooling air
that moves through the system from front to back. If you need to discon-
nect 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). The following data cables should be connected. (See the
layout on page 5-9 for connector locations.)
CD-ROM Drive Cable (IDE)
Floppy Drive Cable (Floppy)
Serial ATA Device Cables (SATA0, SATA1)
Serial ATA LED cable (JSLED)
Control Panel Cable (JF1)

Connecting Power Cables

The P8SCi has one 24-pin primary power supply connector ("ATX power")
at J1 and one 4-pin power connector at J2 for connection to the ATX power
supply. See Chapter 5 for power connector pin definitions.

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
indicators.
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. The other end connects to the Control Panel PCB board, located just
behind the system status LEDs on the chassis. See Chapter 5 for details.
