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.
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
Figure 4-1, “ Mounting the Switch in a Rack”):
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.
Temperature: 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.
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 any source of
electromagnetic noise, for example, a photocopy machine.
a. Power specifications for the switch are shown in Appendix B, “Technical Specifications”
Note: These footpads cushion the switch against shock and vibration. They also provide
for ventilation space between stacked switches.
