Environmental requirements
Altitude and air pressure
For altitudes above 5,000 feet (1,525 meters), you must reduce the maximum short-term
temperature. Reduce this temperature limit by 1 oF (1.8 oC) for every 1,000 feet (304.8 meters)
of elevation above 5,000 feet (1,525 meters). For example, at sea level, the maximum
short-term temperature limit is 120 oF (49 oC). At 10,000 feet (3,050 meters), the maximum
short-term temperature limit is 115 oF (46 oC). The normal operating air pressure range is 9.4 to 15.2 pounds per square inch (psi) (648 to
1,048 millibars).
Air purity
The CMC1, SCC1, and MCC1 Media Gateways contain an air filter to reduce the flow of
particulates through the equipment. Do not install the equipment in an area where it might be
exposed to excessive amounts of any of the following contaminants:
- dust
- lint
- carbon particles
- paper fiber contaminants
- metallic contaminants
