3. HARDWARE SETUP
5) USB/CNR Selection (OC3)
This jumper switches the circuit power between the USB23 connector and the
CNR slot. Note that the default is set to power the USB23 connector.
Setting OC3
Enable CNR [1-2]
Enable USB23 [2-3] (default)
6) Keyboard Power Up (KBPWR)
This allows you to disable or enable the keyboard power up function. Set this
jumper to Enable if you wish to use your keyboard (by pressing <Spacebar>) to
power up your computer. This feature requires an ATX power supply that can
supply at least 300mA on the +5VSB lead. The default is set to Disable because
not all computers have the appropriate ATX power supply. Your computer will not
power ON if you set this to Enable but do not have the appropriate ATX power
supply. NOTE: This jumper must be set in conjunction with Wake On PS2 KB/
PS2 Mouse/CIR in 4.5.1 Power Up Control.
Setting KBPWR
Enable [1-2] (default)
Disable [2-3]
