Small form-factor pluggable (SFP) ports are often employed in telecommunications hardware to take advantage of their lower profile and to provide connections to other network elements. The use of SFP ports has increased the density of ports possible for a given circuit board size, but this increase has previously meant that individual ports are difficult to access. Also, identification of those ports is frustrated by a lack of free space to place labeling. Example embodiments of the present invention address these issues by placing a divider plate between columns of SFP ports that provides surface area adjacent to the SFP ports for affixing labeling. The divider plate is offset from the SFP ports to allow access when the plate is installed. As a result, hardware employing embodiments of the present invention can achieve a higher density of SFP ports with ease of access by personnel assembling or servicing the hardware.

An apparatus, system, and method are provided for venting an enclosure, such as a chassis housing electronic equipment. The method includes receiving, at least one air directing surface, airflow moving in a first direction, the at least one air directing surface being disposed externally from the chassis at a predetermined placement relative to the at least one ventilation surface in a path of the airflow. The at least one air directing surface has a configuration to alter the direction of the airflow between the air directing surface and the at least one ventilation surface. The method also includes redirecting the airflow between the at least one air directing surface and the at least one ventilation surface to at least a second direction using the air directing surface. The predetermined placement and configuration of the at least one air directing surface determine the second direction in which the airflow is discharged, and the second direction is either towards or away from the at least one ventilation surface. Also in the receiving, the airflow is received at least one air directing surface of a bracket configured to attach the chassis to a mounting structure.

A cable tray is provided comprising a housing defining an interior portion, the housing having at least one positioned opening formed therein and also having plural, open ends in communication with the interior portion and the at least one positioned opening for passage of at least one cable therethrough. The housing is adapted to be coupled to at least one external surface, such that at least one of the plural, open ends substantially aligns with at least one open end of a housing of at least one further cable tray.

Stackable cable tray

A chassis having a housing in which at least one card module can be arrange is provided. The chassis is arranged in a first rack horizontally or a second rack vertically wherein the second rack opening width is an integer multiple of the predetermined chassis width. A fan slot and ventilation openings are provided in the chassis to allow for airflow across the card modules. Mounting mechanisms facilitate coupling of the chassis to the first and second rack and include ventilation openings through which air passes.
