2.1 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplug the power cord from the wall socket before touching any
component.
• Use a grounded wrist strap or touch a safely grounded object or 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 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.
Standby Power LED (SB_PWR1)
The motherboard comes with a standby power LED. The green LED lights up
to indicate that the system AC power cable is plugged or not plugged. This is a
reminder that you should shut down the system and unplug the power cable before
removing or installing any motherboard component.
