Before You Connect to the Network
The site where you install the Switch may greatly affect its performance. Please follow these guidelines for setting up the
Switch.
Install the Switch on a sturdy, level surface that can support at least 6.6 lb. (3 kg) of weight. Do not place heavy
objects on the Switch.
The power outlet should be within 1.82 meters (6 feet) of the Switch.
Visually inspect the power cord and see that it is fully secured to the AC power port.
Make sure that there is proper heat dissipation from and adequate ventilation around the Switch. Leave at least
10 cm (4 inches) of space at the front and rear of the Switch for ventilation.
Install the Switch in a fairly cool and dry place for the acceptable temperature and humidity operating ranges.
Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust,
and direct exposure to sunlight.
When installing the Switch on a level surface, attach the rubber feet to the bottom of the device. The rubber feet
cushion the Switch, protect the casing from scratches and prevent it from scratching other surfaces.
Installing the Switch Without the Rack
When installing the Switch on a desktop or shelf, the rubber feet included with the Switch should first be attached. Attach
these cushioning feet on the bottom at each corner of the device. Allow enough ventilation space between the Switch and
any other objects in the vicinity.
