IrDA Tx/Rx Header (CN1)
This connector supports the optional wireless transmitting and
receiving infrared module. This module mounts on to a small
opening on system cases that support this feature. You must also
configure the setting through BIOS setup to select whether
UART2 is directed for use with COM2 or IrDA

Power LED and Keylock (CN2)
You can use an LED to indicate when the CPU card is on. Pin 1
of CN2 supplies the LED's power, and Pin 3 is the ground.
You can use a switch (or a lock) to disable the keyboard so the PC
will not respond to any input. This is useful is you do not want
anyone to change or stop a running program. Connect the switch
between Pins 4 and 5 of CN2
