Quick Installation Guide

Warning!

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. Only

experienced electronics personnel should open the

PC chassis.

Caution!

Always ground yourself to remove any static

charge before touching the CPU card. 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 in a static-dissipative

surface or static-shielded bag when they are not

in the chassis.
