1.1 Before You Proceed
Take note of the following precautions before you install motherboard components or
change any motherboard settings.
1.2 Motherboard Overview
Before you install the motherboard, study the configuration of your chassis to ensure
that the motherboard fits into it. Refer to the chassis documentation before installing
the motherboard.

1.2.1 Placement Direction

When installing the motherboard, make sure that you place it into the chassis in the
correct orientation. The edge with external ports goes to the rear part of the chassis.
Caution!
!
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 com-
ponents 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.
Warning! Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and dam-
age motherboard components.
