You can connect either the AC’97 or the HDA connector, depending on your motherboard. Locate the
internal audio connectors from your motherboard or sound card and connect the corresponding audio
cable. Consult your motherboard or sound card manual for the pin-out positions. Even if your system
supports both standards, only use one connector.

Connected to your front panel are LED and switch leads for power, reset, and
HDD activity. Attach these to the corresponding connectors on your
motherboard. Consult your motherboard manual for specific pin header
locations. For LEDs, colored wires are positive ( + ). White or black wires are
negative ( – ). If the LED does not light up when the system is powered on, try
reversing the connection. For more information on connecting LEDs to your
motherboard, see your motherboard user’s manual.
Tip: Polarity (positive and negative) does not matter for switches.
