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 55 °C (32 to 130 °F)
and its humidity within 5% to 95%, 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 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.
