Selecting a Site
EdgeIron 4802CF 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 50 °C (32 to
122 °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.
