Choosing a Site for the Routers
Observe these requirements when planning the installation of the router.

If you plan to install the routers in an equipment rack, check to be
sure that the rack is safely secured so that it will not tip over.
Devices in a rack should be installed starting at the bottom, with
the heavier devices near the bottom of the rack.

If you plan to install the routers on a table, check to be sure that the
table is level and stable.

The power outlet should be located near the routers and be easily
accessible.

The site should allow for easy access to the ports on the front of
the routers, so that you can easily connect and disconnect cables,
and view the port LEDs.

The site should allow for adequate air flow around the unit and
through the cooling vents on the front and rear panels. (The
ventilation direction in units that have a cooling fan is from front to
back, with the fan on the back panel drawing the air out of the unit.)

The site should not expose the routers to moisture or water.

The site should be a dust-free environment.

The site should include dedicated power circuits or power
conditioners to supply reliable electrical power to the network
devices.

Do not install the routers in a wiring or utility box because it will
overheat and fail from inadequate airflow.
Warning
Routers should not be stacked on top of one another on a table or
desktop because that could present a personal safety hazard if you
need to move or replace routers.
