Hardware Installation

2.7.2 PS/2 Mouse Port

The PS/2 mouse port is a 6-pin connector on the system board. Attach the 6-pin mouse port cable, which is mounted on a card- edge bracket, to connector J2. Make sure the red wire on the PS/2 mouse connector is aligned with pin 1 of connector J2. Mount the card-edge bracket to the system chassis.

The PS/2 mouse port uses IRQ12. If a mouse is not connected to this port, the system will reserve IRQ12 for other expansion cards.

Warning:

Make sure to turn off your computer prior to connecting or disconnecting a mouse. Failure to do so may damage the system board.
