Characteristics Requirements
Mounting
Desktop installations: Provide a flat table or shelf surface.
Rack-mount installations: Use a 19-inch (48.3-centimeter) EIA standard equipment rack that is
grounded and physically secure.You also need the rack-mount kit supplied
with your switch.
Access Locate the switch in a position that lets you access the front panel RJ-45
ports,view the front panel LEDs, and access the rear-panel stacking port(s)
and power connector.
Power source Provide a power source within 6 feet (1.8 meters) of the installation
location.Power specifications for the switches are shown in Appendix A.Be
sure the AC outlet is not controlled by a wall switch,which can accidentally
turn off power to the outlet and the switch.
Environmental Install the switch in a dry area,with ambient temperature between 0 and
Temperature: 40ºC (32 and 104ºF).Keep the switch away from heat sources such as
direct sunlight,warm air exhausts, hot-air vents, and heaters.
Operating humidity: The installation location should have a maximum relative humidity of
90%,non-condensing.
Ventilation: Do not restrict airflow by covering or obstructing air inlets on the sides of
the switch.Keep at least 2 inches (5.08 centimeters) free on all sides for
cooling.Be sure there is adequate airflow in the room or wiring closet where
you intend to install the switch.
Operating conditions: Keep the switch at least 6 ft (1.83 m) away from nearest source of electro
magnetic noise,such as a photocopy machine.
After confirming that your site meets the requirements in Table 4-1,you are ready toinstall the switch.
