Installation Guidelines
Please follow these guidelines for setting up the Switch:
• Install the Switch on a sturdy, level surface that can support at least 13.9 lb. (6.3 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.
