Selecting A Site For The Switch - Allied Telesis AT-x220-28GS Installation Manual

Selecting a site for the switch

You can install an AT-x220-28GS switch on a table or desktop, in a
standard 19-inch equipment rack, or on a wall.
Observe the following requirements when choosing a site for your switch:
If you are installing the switch on a table, verify that the table is

level and secure.
If you plan to install the switch in an equipment rack, verify that the

rack is safely secured and 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 are installing the switch on a wall, ensure that the wall is

sturdy enough to hold the switch's weight. You may need to
position the switch so that it can be screwed into the wall's framing
timber or an equivalent structural element.
The power outlet for the switch should be located near the unit and

should be easily accessible.
The site should provide for easy access to the ports on the front of

the switch. This will make it easier for you to connect and
disconnect cables, as well as view the switch's 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.)
Do not place objects on top of the switch.

Do not expose the switch to moisture or water.

Ensure that the site is in a dust-free environment.

Do not install the switch in a wiring or utility box because it might

overheat and fail from inadequate airflow.
You should use dedicated power circuits or power conditioners to

supply reliable electrical power to the network devices.
Warning
Switches should not be stacked on a table or desktop. They could
present a physical safety hazard if you need to move or replace
switches.  E91
