Safety Guidelines
•
The air baffle assembly is always installed in the appliance except when you
are installing or removing the components that are located under the air baffle
cover.
•
When the air baffle assembly is installed in the appliance, the air baffle cover
is always closed.
•
Microprocessor socket 2 always contains either a microprocessor baffle or
a microprocessor.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside the appliance. To prevent
static damage, discharge static electricity from your body before you touch any of
your system’s electronic components. You can do so by touching an unpainted
metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
•
When unpacking a static-sensitive component from its shipping carton, do not
remove the component from the antistatic packing material until you are
ready to install the component in your system. Just before unwrapping the
antistatic packaging, be sure to discharge static electricity from your body.
• When transporting a sensitive component, first place it in an antistatic
container or packaging.
•
Handle all sensitive components in a static-safe area. If possible, use
antistatic floor pads and workbench pads.
•
Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed printed circuitry.
• Do not leave the device where others can handle and possibly damage the
device.
•
Take additional care when handling devices during cold weather, because
heating reduces indoor humidity and increases static electricity.
