Preparing the
Site
Be sure to observe the following guidelines when planning the
installation of your chassis.
❑ Make sure power for the chassis is accessible and cables can be
easily connected.

radios, transmitters, broadband amplifiers, power lines,
fluorescent or halogen light fixtures.
❑ Air flow around the chassis and through its vents on the rear panel
should not be restricted.
❑ If you are using the chassis on a desktop, make sure it is placed on
a level, secure surface.
❑ Do not place objects on top of the chassis.
❑ Do not expose the chassis to moisture or water.
❑ Make sure the chassis is in a dust-free environment.
❑ Use dedicated power circuits or power conditioners to supply
reliable electrical power to the network devices.
