Selecting a Site

TigerSwitch 10/100/1000 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 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, transmitters, etc.

◆

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.
