Chapter 2 Preparing for Installation
Preparing Your Site for Installation
•
Always disconnect all external cables before lifting or moving the appliance.
• Ensure that your footing is solid, and balance the weight of the object between your feet.
•
Lift the appliance slowly; never move suddenly or twist your body as you lift.
• Keep your back straight and lift with your legs, not your back. If you must bend down to lift the
appliance, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.
•
Lift the appliance from the bottom; grasp the underside of the appliance exterior with both hands.

a floor plan of the site and the equipment rack where the Cisco NAC Appliance CAM/CAS will be
housed. Determine the location of any existing appliances and their interconnections, including
communications and power. Following the airflow guidelines (see
Airflow Guidelines, page 2-9 )
ensures that adequate cooling air is provided to the appliance.
All personnel involved in the installation of the appliance, including installers, engineers, and
supervisors, should participate in the preparation of a MOP for approval by the customer. For more
information, see
