Installation Guidelines
This section will discuss the hardware installation guidelines that the user must follow in
order to properly and safely install this switch into the appropriate environment.
Visually inspect the power cord and see that it is fully secured to both the power
connector, on the Switch, and the electrical outlet that supplies power.
Install the Switch in a fairly cool and dry place within the acceptable operating
temperature and humidity ranges.
Install the Switch in a site free from strong electromagnetic field generators such as
motors, vibration, dust, and direct exposure to sunlight.
Installing the Switch without a Rack
This section is used to guide the user through installing the Switch in an area other than a
switch rack. Attach the included rubber feet to the bottom of the Switch. Take note that
there should be marked blocks on the bottom of the Switch to indicate where to attach the
rubber feet. These markings are usually found in each corner on the bottom of the device.
The rubber feet cushion the Switch, protecting the casing from scratches and preventing it
from scratching other surfaces.
