A system is designed to facilitate heat transfer via radiation, convection and conduction from components within the system to the external environment and housing. The system includes a thermally conductive plate positioned between a surface of the housing and one or more heat generating components within the housing. A compliant thermally conductive material may then be placed between the heat generating components and the plate to facilitate conductive heat transfer from the component to the plate. From the plate, heat is transferred to the external environment through radiation and convection of air through perforations in the housing which cover a substantial portion of the surface area of the housing. The housing may also be inexpensively manufactured through stamping and may include two mating pieces which interlock using chamfered electrostatic discharge fingers. The housing may also incorporate a metal shroud for enveloping certain ESD sensitive connectors, such as optical couplers.

A water resistant enclosure providing protection to electrical or electronic equipment contained therein includes a three-sided removable cover pivotally coupled to a wall mounting bracket that includes a back panel-base plate combination. The three-sided removable cover further includes an enclosure door that covers the front opening. The three-sided removable cover also includes features to provide for water resistance. These features include an overhang extension from the top side wall of the three-sided removable cover extending to partially cover the front opening and in particular to cover the seam created between the enclosure door and the removable cover, and a gutter surrounding the front opening to divert water therefrom. In addition, the three-sided removable cover and the wall mounting bracket include elements to provide for the proper alignment and orientation thereof when being mated together. In addition, the pivot member and pivot member receiver are attached to the interior of the top side and wall mounting bracket respectively such that the water resistance of the respective surfaces is not compromised.

An equipment enclosure includes a set of features enabling alignment of an electronic component with an L-shaped wall bracket. The bottom of the component rests on a base of the bracket. A rear wall of the bracket includes fastener elements, such as threaded standoffs, and alignment posts that extend forward beyond the standoffs. The rear of the component likewise includes fastener elements, such as captive screws, and alignment openings. During installation, the component is brought into a position in which the alignment openings engage the alignment posts, and then the component is pushed rearward until it abuts the rear wall of the bracket. The fasteners become mutually aligned for subsequent fastening.

A fiber cable storage and management apparatus. The apparatus includes front and rear sections interconnected by a hinge. The front section is configured to hold a length of fiber cable, and both the front and rear sections are slidingly mountable to an electronic chassis. The front section of the fiber cable storage and management apparatus may be alternately retracted out of and inserted into the housing of the electronic chassis. When the front section is retracted out of the electronic chassis housing, the hinge can pivot between a first position in which the front and rear sections of the apparatus are substantially coplanar and a second position in which the front section is rotated below the plane of the rear section. By sliding the front section of the apparatus out of the electronic chassis housing and then rotating the front section downward, easy access is provided to fiber cable stored on the front section.

An enclosure that includes at least first and second pieces of equipment having separate cooling airflows. A baffle is disposed within the enclosure to separate the enclosure into two compartments and to isolate the airflows for each piece of equipment within each of the respective compartments. The baffle includes a step portion to provide for a smooth airflow and to prevent hot spots from being formed on the baffle. The heated airflow from the second compartment is redirected away from the first compartment to an air duct or chimney that transports the heated air from the second compartment to an air output vent. When acting as a chimney, the air duct includes a flue portion, a buffer portion to enhance the convection draft, and an output opening. The separate airflows may be either convection driven or be a forced airflow driven by one or more fans.
