Planning the proper location and layout of your equipment rack or wiring closet is essential
for successful system operation. Equipment placed in an inadequately ventilated area can
cause system overtemperature conditions. In addition, poor equipment placement can make
chassis panels inaccessible and difficult to maintain. Follow these precautions when
planning your equipment locations and connections:
Keep the front of the chassis free from obstructions and away from the exhaust air of
other equipment. Remember that electrical equipment generates heat, and ambient room
temperature alone might not be adequate to cool equipment to acceptable operating
temperatures.
Secure the placement of all chassis panels, modules, and any module slot fillers. The fan
assembly pulls cooling air across the line modules. A loose panel allows too much air
to escape and can redirect the airflow away from active line modules.
