Patent ID: 8115145

Claim:
A system, comprising: an enclosure, suitable for use outside in a wide range of extreme weather conditions, with at least two compartments; a first door operationally coupled to the enclosure such that a first of the two compartments can be opened, the first door including: a controller; a filtration unit for filtering particles and water droplets from air; a fan tray with a heater for drawing in and heating air; one or more cold start recirculation dampers for controlling the flow of heated air; a second door operationally coupled to the enclosure such that a second of the two compartments can be opened; communications equipment, suitable for use indoors over a limited temperature range, within the first compartment; a rectifier unit within the second compartment; wherein, in operation, the controller controls the fan tray with a heater to pull ambient air through the filtration unit, through the fan tray where the air is heated, and through the cold start recirculation dampers, wherein a first portion of the heated air contacts the communications equipment and a second portion of the heated air contacts the rectifier unit as the air passes through the first compartment and the second compartment, respectively, wherein, when a portion of the communications equipment passes a lower threshold temperature, the communications equipment is started, thereby preventing the communications equipment from starting at a temperature that is sufficiently cold to potentially damage components of the communications equipment, wherein, when a portion of the communications equipment passes an upper threshold temperature the controller increases the speed of the fans in the fan tray, thereby drawing more ambient air through the filtration unit to prevent the communications equipment from overheating.
