You can connect both a PS/2 and a serial mouse to the PG 720. When the
PG 720 is supplied, the mouse driver for the trackball and PS/2 mouse is
already loaded.
You can connect an external PS/2 mouse or another external pointing device
to an additional PS/2-compatible mouse connector.

Connecting a PS/2 Mouse
Connect the mouse as follows:
1. Switch off your device.
2. Open the port cover on the left-hand panel.
3. Plug the cable of the PS/2 mouse or another external pointing device into
the mouse connector.
4. Secure the connector with the screws.

Once you have plugged in the external mouse and restarted your PG 720, the
internal trackball is deactivated and remains inactive until the PG 720 is
powered up again without the external mouse.
