2 INSTALLING THE SWITCH
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 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.
