Motherboard information
2.1 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
CAUTION!
• Unplug the power cord from the wall socket before touching any
component.
• Before handling components, use a grounded wrist strap or touch a safely
grounded object or a metal object, such as the power supply case, 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, always remove the AC power
by unplugging the power cord from the power outlet. Failure to do so may
cause severe damage to the motherboard, peripherals, or components.
Standby Power LED
The motherboard comes with a standby power LED that lights up to indicate that
the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you
should shut down the system and unplug the power cable before removing or
plugging in any motherboard component. The illustration below shows the location
of the onboard LED.
