Step 1: Prepare the site
Before you install the switch, make sure that the operating environment meets the site
requirements that are listed in the following table.
Table 8. Site requirements
Requirements
Characteristics
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 that is supplied
with the switch.
Mounting
Locate the switch in a position that allows you to access the front panel RJ-45 ports, view
the front panel LEDs, and access the power connector on the back panel.
Access
Use the AC power cord that is supplied with the switch. Make sure that the AC outlet is
not controlled by a wall switch, which can accidentally turn off power to the outlet and
the switch.
Power source
Route cables to avoid sources of electrical noise such as radio transmitters, broadcast
amplifiers, power lines, and fluorescent lighting fixtures.
Cabling
Temperature. Install the switch in a dry area with an ambient temperature between 0ºC
and 50ºC (32ºF and 122ºF). Keep the switch away from heat sources such as direct sunlight,
warm-air exhausts, hot-air vents, and heaters.
Operating humidity. The maximum relative humidity of the installation location must
not exceed 90%, noncondensing.
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. The
room or wiring closet in which you install the switch must provide adequate airflow.
Operating conditions. Keep the switch at least 6 feet (1.83 meters) away from the nearest
source of electromagnetic noise, such as a photocopy machine.
Environmental
Step 2: Protect against electrostatic
discharge
WARNING:
Static electricity can harm delicate components inside your system. To
prevent static damage, discharge static electricity from your body before you touch any
of the electronic components, such as the microprocessor. You can do so by periodically
touching an unpainted metal surface on the switch.
