Cautions
A caution indicates a possible hazard to equipment that could result in equipment
damage. Observe the following cautions when operating or working on this
equipment:
• This equipment is meant to be installed in a restricted access location.
• When installing this equipment, do not attach the power cord to building surfaces.
• Products that have no on/off switch, and use an external power supply must be installed in
proximity to a main power outlet that is easily accessible.
• Use the correct voltage setting. If this product lacks auto-ranging power supplies, before
applying power ensure that each power supply is set to match the power source.
• Provide proper ventilation. To prevent product overheating, provide equipment
ventilation in accordance with the installation instructions.
• Do not operate with suspected equipment failure. If you suspect product damage or

• This unit may have more than one power supply cord. Disconnect all power supply cords
before servicing to avoid electric shock.
• Follow static precautions at all times when handling this equipment. Servicing should be
done in a static-free environment.
• To reduce the risk of electric shock, plug each power supply cord into separate branch
circuits employing separate service grounds.
Electrostatic Discharge (ESD) Protection
Electrostatic discharge occurs when electronic components are improperly handled
and can result in intermittent failure or complete damage adversely affecting an
electrical circuit. When you remove and replace any card from a frame always follow
ESD-prevention procedures:
• Ensure that the frame is electrically connected to earth ground through the power cord or
any other means if available.
• Wear an ESD wrist strap ensuring that it makes good skin contact. Connect the grounding
clip to an
unpainted surface
of the chassis frame to safely ground unwanted ESD voltages. If
