Static Electricity Precautions

Components on this mainboard can be damaged by static

electricity. Take the following precautions when unpacking the

mainboard and installing it in a system.

1. Keep the mainboard and other components in their original

static-proof packaging until you are ready to install them.

2. During installation, wear a grounded wrist strap if possible. If

you don’t have a wrist strap, discharge static electricity by

touching the bare metal of the system chassis.

3. Handle the mainboard carefully by the edges. Avoid touching

the components unless it is absolutely necessary. During

installation put the mainboard on top of the static-protection

packaging it came in with the component side facing up.

Pre-Installation Inspection

1. Inspect the mainboard for damage to the components and

connectors on the board.

2. If you suspect that the mainboard has been damaged, do not

connect power to the system. Contact your mainboard vendor

and report the damage.
