supply unit to ATX1. The connector is keyed so that it can only be installed

from the case fan power connector CASE FAN1. Connect the power cable from
the fan to CASE FAN1.

Note: If you install an optional infrared port, it requires resources that are
normally used by the external serial port COM2, so you cannot use the infrared
port and COM2 at the same time. You can use the setup utility to activate the
infrared port or the COM2 serial port. See Chapter 3 for more information.
