Asus A8N-SLI SE manual Before you proceed, Onboard LED

2.1Before you proceed

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

•Make sure that your power supply unit (PSU) can provide at least the minimum power required by your system. See “7. ATX power connectors” on page 2-25 for details.

•Unplug the power cord from the wall socket before touching any component.

•Use 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

•Hold components by the edges to avoid touching the ICs on them.

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

•Before 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.
