WARNING: Electrostatic Sensitive Device (ESD)
Static electricity can easily damage your motherboard and will void your motherboard warranty. Keep the motherboard
and other system components in their anti-static packaging until you are ready to install them. Touch a grounded surface
before you remove any system component from its protective anti-static packaging. Unpacking and installation should be
done on a grounded, anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same
points as the anti-static mat. During configuration and installation touch a grounded surface frequently to discharge any
static electrical charge that may have built up in your body. Avoid touching the components when handling the
motherboard or a peripheral card. Handle the motherboard and peripheral cards either by the edges or by the peripheral
card case-mounting bracket.
WARNING: Misplaced Jumper Damage
Incorrect jumpers and connectors settings may lead to damage to your motherboard and will void your motherboard
warranty. Please pay special attention to not connect these headers in the wrong direction. DO NOT change ANY jumpers
while the motherboard has power.
