Step 2: Installing the Switch
Install the switch using one of the following methods:
Installing the Switch on a Flat Surface
The switch ships with four self-adhesive rubber footpads. Attach one rubber foot pad into each of
the four concave depressions on the base of the switch.
Note: These footpads cushion the switch against shock and vibration. They also provide
for ventilation space between stacked switches.
Installing the Switch in a Rack
To install the switch in a rack, use the 19-inch rack-mount kit (supplied with your switch) with the
following procedure (refer to
1. Attach the supplied mounting brackets to the side of the switch using the screws provided in
the rack-mount kit.
2. Tighten the screws with a #1 Phillips screwdriver to secure each bracket.
3. Orient the switch to align the unused mounting holes in the brackets with appropriate holes in
the rack.
4-2
Install the switch in a dry area, with ambient temperature in the range 0–55ºC
(32–131ºF). Keep the switch away from heat sources such as direct sunlight,
warm air exhausts, hot-air vents, and heaters.
The installation location should have a maximum relative humidity of 90%,
non-condensing.
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.
Keep the switch at least 6 ft. (1.83 m) away from any source of
electromagnetic noise, for example, a photocopy machine.
