N20xx Series Installation
Site Preparation
N20xx Series switches can be mounted in a standard 48.26 cm (19-inch) rack
or placed on a flat surface.
Make sure that the chosen installation location meets the following site
requirements:
•
Power
— The switch is installed near an easily accessible 100–240 VAC,
50–60 Hz outlet.
•
Clearance
— There is adequate front and rear clearance for operator
access. Allow clearance for cabling, power connections, and ventilation.
•
Cabling
— The cabling is routed to avoid sources of electrical noise such
as radio transmitters, broadcast amplifiers, power lines, and fluorescent
lighting fixtures.
•
Ambient Temperature
— The ambient switch operating temperature
range is 0 to 45ºC (32 to 113ºF) at a relative humidity of up to 95 percent,
non-condensing.
NOTE: Decrease the maximum temperature by 1°C (1.8°F) per 300 m (985 ft.) above
900m (2955 ft.).
•
Relative Humidity
— The operating relative humidity is 8% to 85%
(noncondensing) with a maximum humidity gradation of 10% per hour.
