Temperature Requirements
The switch requires an operating temperature of 32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius). If
the switch is not operating, the temperature must be between –40 to 158 degrees Fahrenheit (–40 to 70 degrees
Celsius).
Humidity Requirements
Buildings in which the climate is controlled by air-conditioning in the warmer months and by heat during the
colder months usually maintain an acceptable level of humidity for the switch equipment. However, if the
switch is located in an unusually humid location, use a dehumidifier to maintain the humidity within an
acceptable range.
Altitude Requirements
Altitude rating is based on power supply installed; see critical components list in the system CB report for
altitude rating.
