The present invention relates to a telecommunications connection module including a housing and connection locations mounted to a front face of the housing. The connection locations are removably mounted to the front face allowing access to an interior side of the connection locations from outside the housing and arranged to two rows. A shelf divide the interior of the housing into two spaces allowing cables to be directed to one or the other of the rows of connection locations. The housing may also include integral mounting recesses for mounting the housing to a telecommunications equipment rack. The rear of the housing may also include a removable portion and angled portions adjacent the sides which are offset toward the front face. The present invention also relates to a telecommunications connection system including a rack and at least one connection module mounted to the rack, the rack including a front and a rear cable management structure. The rear cable management structure includes at least two vertical cable channels, one of which is adapted to manage cable which do not extend from modules mounted to the equipment rack. The present invention also relates to a method of installing a new equipment rack into an existing telecommunication equipment installation into a gap in the existing lineup which is narrower than the existing equipment racks. The new rack includes a rear vertical cable channel for managing cables extending from devices mounted in adjacent or nearby equipment racks but which are not connected to the new rack.
