Electrostatic Discharge Information

A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions to prevent damage. To prevent
electrostatic damage:
Transport products in static-safe containers such as conductive tubes, bags, or boxes.
Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
Cover workstations with approved static-dissipating material. Provide a wrist strap
connected to the work surface and properly grounded tools and equipment.
Keep work area free of non-conductive materials such as ordinary plastic assembly aids
and foam packing.
Always be sure you are properly grounded when touching a static-sensitive component or
assembly.
Avoid touching pins, leads, or circuitry.
Always place drives PCB assembly–side down.
Use conductive field service tools.

Equipment Symbols

The following symbols are located on applicable components of the workstation and should be
observed when servicing the workstation to avoid personal injury or damage to the components:
WARNING: Any surface or area of the equipment marked with these symbols
indicates the presence of a hot surface or hot component. If this surface is
contacted, the potential for injury exists. To reduce risk of injury from a hot
component, allow the surface to cool before touching.
WARNING: Any surface or area of the equipment marked with these symbols
indicates the presence of electrical shock hazards. The enclosed area contains no
operator-serviceable parts. To reduce risk of personal injury from electrical shock
hazards, do not open this enclosure.
WARNING: Any RJ-45 receptacle marked with this symbol indicates a Network Interface
Connection. To reduce risk of electrical shock, fire, or damage to the equipment, do not plug
telephone or telecommunications connectors into this receptacle.
