EUP LAN / EUP Audio Jumper (EUP_LAN1, 3-pin jumper, see p.2 No. 35) (EUP_AUDIO1, 3-pin jumper, see p.2 No. 31) Default (Enable EuP) Note: EUP_LAN and 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. Please be noticed that when EUP_LAN jumper is set to enabled, the Wake-On-LAN function under S3 (Suspend to RAM), S4 (Suspend to Disk), and S5 (Soft Off) will be disabled.
