Chapter 3: 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 45 °C (32 to 113 °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 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.
Equipment Checklist
After unpacking the switch, check the contents to be sure you have received all the
components. Then, before beginning the installation, be sure you have all other
necessary installation equipment.
