Selecting a Site
Switch 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 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 2.44 m
(8 feet) of each device and is powered from an independent circuit
breaker. As with any equipment, using a filter or surge suppressor is
recommended.
