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 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 LED indicators to be clearly visible

•Make sure that 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 m (6.6 feet) of each device

-is powered from an independent circuit breaker
