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.
