2.5 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.
