Selecting a Site for the Stack
Here are the site guidelines for the stack:
Note
The switches of the stack should be installed on a table or in an
equipment rack. They should not be installed on a wall.
 The power outlets should be located near the switches and be
easily accessible.
 The site should allow for easy access to the ports on the front of
the switches, so that you can easily connect and disconnect
cables, and view the port LEDs.
 The site should allow for adequate air flow around the units and
through the cooling vents on the front and rear panels. (The
ventilation direction in a unit with a cooling fan is from front to back,
with the fan on the back panel drawing the air out of the unit.)
 If you are installing the switches of the stack in an equipment rack,
you should verify that the rack is safely secured so that it will not tip
over. You should install devices starting at the bottom of the rack,
with the heavier devices near the bottom.
 If you are installing the stack on a table or desk, you should verify
that the table or desk is level and secure.
 If you are installing the stack on a table or desk, you should place
the units side-by-side. Do not stack them on top of each other
because that could pose a safety hazard.
 The site should not expose the switches 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.
 The site should not expose the twisted pair cabling to sources of
electrical noise, such as radio transmitters, broadband amplifiers,
power lines, electric motors, and fluorescent fixtures.
 Switch ports are suitable for intra-building connections, or where
non-exposed cabling is required.
 Do not place objects on top of the switches.
 Do not install the switches in a wiring or utility box because they
will overheat and fail from inadequate airflow.
