Step 6 Connect the Mouse Cable
The mouse connector (P6) is a ten-pin dual-inline berg. Attach a standard serial cable from the mouse connector to a
standard DB9 serial port connector mounted externally on the chassis. Pin 10 should be cut because it is not used.

Step 7 Connect Cables
When attaching chassis connectors to the motherboard, make sure you connect the correct connector end. Most
connector wires are color-coded. Match the color of the wires leaving the switch or LED to the same pin on the
connector end. There may be more than one connector with the same color-coded wires. If so, follow the wire to the
switch or LED. Pin 1 of all connectors can be determined easily. Each jumper is surrounded by a white line etched on
the motherboard. One end of the white line always ends in a arrow. Pin 1 is always at the pointed end of the white line.
Pin 1 is designated by a square pad on the motherboard graphic. Connect the following cables to the motherboard:
• Reset Switch cable to P34,
• Speaker cable to P33,
• Keyboard Lock cable to P31,
• Turbo Switch cable to P28,
• Onboard Diag LED is P21,
• Turbo LED cable to P27,
• Password LED cable to P32,
• Sleep switch cable to P30,
• IDE hard disk drive activity LED cable to P29.
Monitor power switch for Green PC mode, and
• Auxiliary power off cable to P12.
