Site Environmental Requirements
Planning a proper location for the switch and layout for your equipment rack or 
wiring closet is essential for successful system operation. You should install the 
switch in an enclosed, secure area, ensuring that only qualified personnel have 
access to the switch and control of the environment. Equipment that is placed too 
closely together or that is inadequately ventilated can cause system 
overtemperature conditions. In addition, poor equipment placement can make 
chassis panels inaccessible and difficult to maintain.
