Abstract: A communication cabinet and methods for installing active component into a communication cabinet, the method includes: removing at least one passive communication connector being connected by at least one wire to at least one customer connector within the communication cabinet; installing at least one printed circuit board that are connected to at least one active communication component and to at least one slim edge connector; wherein the printed circuit boards are shaped such as to be completely positioned within the communication cabinet; and connecting the at least one wire to the at least one slim edge connector.

Abstract: A communication cabinet, that includes: at least one fan, adapted to rotate at a first direction during a first period and to rotate at a second opposing direction during a second period; a controller, adapted to control the at least one fan; and at least one filter positioned to prevent dust from entering the communication cabinet and to allow air to exit the communication cabinet such as to remove dust from the filter during the second period. A method for dust removal from a filter, the method includes: providing communication cabinet that comprises the filter, whereas the filter is positioned such as to prevent dust from entering the communication cabinet; rotating at least one fan at a first direction during a first period such as to cool at least one communication circuit installed within the communication cabinet; and rotating the at least one fan at a second opposing direction during a second period such as to remove dust from the at least one filter.
