Preparing the Site
Before you install your switch, be sure your operating environment meets the operating
environment requirements in Table 4-1.
Table 4-1. Site Requirements
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.
Stacking If you intend to stack two or more switches, be sure the mounting surface
can safely support the switch stack. Also, be sure there is adequate space
around the stack for ventilation and cooling.
After confirming that your site meets the requirements in Table 4-1, you are ready to
install the switch.
