Abstract: A telecommunications and networking equipment housing including: a body defining a slot adapted to receive a shelf; and an adjustable key component coupled to the body and defining a channel adapted to receive a fixed key component coupled to the shelf, wherein the channel is movable between a first location and a second location along a front edge of the slot. The fixed key component coupled to the shelf is aligned with the channel defined by the adjustable key component in either the first location or the second location. The adjustable key component is translatable along the front edge of the slot such that the channel is movable between the first location and the second location.

Abstract: A network device includes a support structure configured to support communication equipment, the support structure including at least a non-conductive vertical substrate, a pair of conductive strips arranged on a front-facing surface of the non-conductive vertical substrate and configured in electrical communication with a power source, and one or more alignment blocks, where each of the one or more alignment blocks includes a touch-proof cage configuration that has spacing dimensions configured to prevent a normal-sized human finger from contacting the pair of conductive strips to reduce the risk of electric shock. Each of the one or more alignment blocks includes slots configured to guide one or more power connectors of a circuit board for making electrical contact with the pair of conductive strips when the circuit board is installed on the support structure.

Abstract: A network element incudes a shelf including a main backplane having a busbar system thereon, wherein the shelf supports any of port modules and switch modules, wherein the modules interconnect to one another via cables; extension brackets configured to connect to one of a top and a bottom of the shelf; and a power shelf configured to connect to the extension brackets, wherein the power shelf supports one or more power modules; wherein the power shelf is configured at a top of the shelf when the shelf is located, in any of a rack, frame, and cabinet, above another shelf, and wherein the power shelf is configured at a bottom of the shelf when the shelf is located below the another shelf.

Abstract: Systems and methods for controlling airflow through a casing or shelf assembly are provided. An apparatus, according to one implementation, includes a mount plate configured to be attached to a side panel of a casing for housing network equipment. For example, the mount plate may include a window. The apparatus also includes one or more hinges arranged at an edge of the window of the mount plate and a baffle pivotably attached to the one or more hinges. The baffle can be arranged within a range of positions with respect to the mount plate to control an amount of airflow through the window. Within these range of positions, the baffle is configured to redirect the airflow in a front-to-back direction through the casing.

Abstract: Systems and method for managing cables in a front-to-rear air-cooled housing of a networking system are provided, whereby airflow is controlled to flow through an air filter. According to one embodiment, a network element configured as a cable gate includes a brush and a frame having at least one slot. Each slot is configured to join an interior space of a housing with an exterior space outside the housing. The brush has bristles covering, in an unbiased condition, the at least one slot to reduce air flow between the interior space and the exterior space. The bristles are configured to be displaceable to enable cables to extend through the at least one slot.

Abstract: A method for testing a mechanical integrity of an insulating layer covering a conductor in a cable, a longitudinal void being defined inside the insulating layer in a region of the conductor. A first end of the insulating layer is blocked. A compressed gas is injected at a second end of the insulating layer so that the gas enters and travels the longitudinal void inside the insulating layer towards the first end. A gas pressure inside the insulating layer is measured at least near the second end. Injection of the compressed gas is stropped after a predetermined injection time period. A variation of the gas pressure inside the insulating layer is monitored during a diagnostic time window succeeding to a transitional time period following the stopping of the injection. Integrity of the insulating layer is determined based on the variation of the gas pressure during the diagnostic time window.

Abstract: A vehicle for use on a live line. The vehicle is provided with three coplanar traction wheels mounted on a frame and spaced along a first longitudinal axis parallel to the live line and above therefrom. The vehicle is also provided with two movable coplanar pressure wheels mounted on the frame and spaced along a second longitudinal axis parallel to the line and below therefrom. The vehicle has a driving motor mounted on the frame, for driving the traction wheels. The motor has a source of energy, such as batteries. The vehicle has a pressure mechanism mounted on the frame and coupled to the pressure wheels, for maintaining the line squeezed between the traction wheels and the pressure wheels. The vehicle has a control mechanism coupled to the motor for controlling the motor. Thereby, in use, the vehicle is moved along the line. The vehicle can also be provided with a de-icing tool. The de-icing tool has a collar with two parts opening and closing around the line.
