2.1Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

ïUnplug the power cord from the wall socket before touching any component.

ïUse a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity.

ïHold components by the edges to avoid touching the ICs on them.

ïWhenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

ïBefore you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

When lit, this green LED indicates that the system is ON, in sleep mode, or in soft-off mode, a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component.
