Selecting a Site for the Switch

Observe the following requirements when choosing a site for your switch:

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 table, verify that the table is level and secure.

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.

Air flow around the unit and through its vents on the side and rear should not be restricted so that the switch can maintain adequate cooling.

Do not place objects on top of the switch.

Do not expose the switch to moisture or water. Ensure that the site is a dust-free environment.

You should use dedicated power circuits or power conditioners to supply reliable electrical power to the network devices.
