power surges.
17. CAUTION: Always ground yourself to remove any static charge before touching
the motherboard, backplane, or add-on cards. Modern electronic devices are
very sensitive to static electric charges. As a safety precaution, use a grounding
wrist strap at all times. Place all electronic components on a static-dissipative
surface or in a static-shielded bag when they are not in the chassis.
18. CAUTION: Any unverified component could cause unexpected damage. To
ensure the correct installation, please always use the components (ex. screws)
provided with the accessory box.
