may cause undesired operation.

16. CAUTION: Always completely disconnect the power cord from your chassis

whenever you work with the hardware. Do not make connections while the

power is on. Sensitive electronic components can be damaged by sudden

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-dissipating

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.

components.
