Protection from Airborne Pollutants

Cisco ISR platforms are designed for and intended to be deployed/installed in environmentally
controlled spaces that maintain ambient conditions meeting the environmental parameters defined in the
documentation for the equipment. Sites that subject the equipment to direct exposure to airborne
pollutants from sources such as automotive and other vehicular traffic, industrial sites, or other sources
that generate pollutants, are not supported. Such exposure may include corrosive materials that can lead
to early failure of the equipment.
