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
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 chassis has adequate ventilation.
• Do not place the chassis within a closed-in wall unit or on top of cloth, which can act as insulation.
• Do not place the chassis where it will receive direct sunlight, particularly in the afternoon.
• Do not place the chassis next to a heat source of any kind, including heating vents.
• Adequate ventilation is particularly important at high altitudes. Make sure that all the slots and openings
