Preparing for Installation
Revised: July 2012
Planning a proper location for the switch and the layout of your equipment rack or wiring closet is
essential for successful system operation. Equipment placed too close together or inadequately
ventilated can cause system overtemperature conditions. In addition, poor equipment placement can
make network interface connections inaccessible and difficult to maintain.
