Choosing a Site for the Chassis

66
Observe these site requirements.
If you are installing the device in an equipment rack, check that the

rack is safely secured so that it will not tip over. Devices should be
installed in the rack starting at the bottom, with the heavier devices
near the bottom of the rack.
The power outlet should be located near the chassis and be easily

accessible.
The site should allow for easy access to the ports on the front of

the switch, 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 is from front to back, with the fans on the back
panel drawing the air out of the unit.)
The site should not expose the switch 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.
Twisted pair cabling should not be exposed to sources of electrical

noise, such as radio transmitters, broadband amplifiers, power
lines, electric motors, or fluorescent fixtures.
Switch ports are suitable for intra-building connections, or where

non-exposed cabling is required.
Do not install the device in a wiring or utility box that has

inadequate airflow because it might overheat and fail.
