Item or Task
Choose the number and types of switches you
want to install.
Rack or Cabinet
Verify that your rack or cabinet meets the
minimum requirements for the installation of
the switch.
Plan rack or cabinet location, including required

The switch must be installed in a rack or cabinet housed in a dry, clean, well-ventilated,
and temperature-controlled environment.
Ensure that these environmental guidelines are followed:
The site must be as dust-free as possible, because dust can clog air intake vents and
filters, reducing the efficiency of the switch cooling system.
Maintain ambient airflow for normal switch operation. If the airflow is blocked or
restricted, or if the intake air is too warm, the switch might overheat, leading to the
switch temperature monitor shutting down the switch to protect the hardware
components.
