2.7 Jumpers Setup The illustration shows how jumpers are setup. When the jumper cap is placed on pins, the jumper is "Short". If no jumper cap is placed on pins, the jumper is "Open". The illustration shows a 3-pin jumper whose pin1 and pin2 are "Short" when jumper cap is placed on these 2 pins. Jumper Setting Description PS2_USB_PWR1 1_2 (see p.11 No. 1) 2_3 Short pin2, pin3 to enable +5VSB (standby) for PS/2 +5V +5VSB or USB wake up events. Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power supply. Clear CMOS (CLRCMOS1, 2-pin jumper) (see p.11 No. 20) 2-pin jumper Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS includes system setup information such as system password, date, time, and system setup parameters. To clear and reset the system parameters to default setup, please turn off the computer and unplug the power cord from the power supply. After waiting for 15 seconds, use a jumper cap to short 2 pins on CLRCMOS1 for 5 seconds. EUP Audio Jumper (EUP_AUDIO1, 3-pin jumper) (see p.11 No. 23) EUP_LAN1 EUP_AUDIO1 Default (Enable EuP) Note: EUP_AUDIO jumper design decreases the power consumption of this motherboard to meet EuP standard. With an ASRock EuP ready motherboard and a power supply that the 5VSB power efficiency is higher than 50% under 100mA current consumption, your system is able to submit EuP standard. The default setting (short pin1 and pin2) is EuP enabled. If you want to disable this power saving function, you may short pin2 and pin3. EUP_LAN1 EUP_AUDIO1 (Disable EuP) 20
