Selecting a Site
EZ Switch 10/100/1000 units can be mounted in a standard 19-inch
equipment rack or on a flat surface. Be sure to follow the guidelines below
when choosing a location.
• The site should:
- be at the center of all the devices you want to link and near a power
outlet.
- be able to maintain its temperature within 0 to 40 °C (32 to 104 °F) and
its humidity within 10% to 90%, non-condensing
- provide adequate space (approximately five centimeters or two inches)
on all sides for proper air flow
- be accessible for installing, cabling and maintaining the devices
- allow the status LEDs to be clearly visible
• Make sure twisted-pair cable is always routed away from power lines,
fluorescent lighting fixtures and other sources of electrical interference,
such as radios and transmitters.
• Make sure that the unit is connected to a separate grounded power outlet
that provides 100 to 240 VAC, 50 to 60 Hz, is within 2 m (6.6 feet) of
each device and is powered from an independent circuit breaker. As with
any equipment, using a filter or surge suppressor is recommended.
