1. Getting Started

1.1 Safety Precautions

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.
