Site Requirements

Planning a proper location for the switch and layout of the equipment rack or wiring closet is essential for
successful system operation. These sections describe some of the basic site requirements that you should be
aware of as you prepare to install your switch, including the following:
• Environmental factors can adversely affect the performance and longevity of your system.
• Install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the
• Equipment that is placed too closely together or that is inadequately ventilated may cause system
• Poor equipment placement can make chassis panels inaccessible and difficult to maintain.
• The switch requires a dry, clean, well-ventilated, and air-conditioned environment.
• To ensure normal operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the
• Multiple switches can be rack mounted with little or no clearance above and below the chassis. However,

Temperature

Temperature extremes may cause a system to operate at reduced efficiency and cause a variety of problems,
including premature aging and failure of chips, and failure of mechanical devices. Extreme temperature
fluctuations may also cause chips to become loose in their sockets. Observe the following guidelines:
• Ensure that the system is operating in an environment that is—
