Chapter 2 Preparing to Install the Wide Area Virtualization Engine

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.
