A fan tray apparatus and method includes a mounting body portion having a length and a width. The mounting body portion further includes first and second longitudinal sides and first and second lateral sides. A plurality of fans is operatively attached to the mounting body portion. The plurality of fans includes a first set of fans, a second set of fans, and a third set of fans. The first set of fans is positioned along the first lateral side. The second set of fans is positioned along the second lateral side. The third set of fans is positioned between the first set of fans and the second set of fans, the third set of fans positioned on a middle portion of mounting body portion.

Fan tray apparatus and method

An apparatus and method for providing redundant power and redundant fan speed control to a plurality of fans is provided. A first power supply input is electrically connected to a second power supply input to provide a combined power supply input. First and second fan speed controllers each having an input and an output are provided, along with first and second power converters each having an input and an output. The combined power supply input is electrically connected to the input of the first fan speed controller and the input of the first power converter. The combined power supply input is also electrically connected to the input of the second fan speed controller and the input of the second power converter. The output of the first fan speed controller is electrically combined with the output of the second fan speed controller to provide a combined fan speed control signal. The combined fan speed control signal is electrically connected to the plurality of fans. The output of the first power converter is electrically combined with the output of the second power converter to provide a combined fan voltage. The combined fan voltage is electrically connected to the plurality of fans.

Apparatus and method of providing redundant power and redundant fan speed control to a plurality of fans

An interface panel for providing telecommunication signals to a plurality of electronic modules housed within an electronics cabinet is provided. A bracket member includes a plurality of openings. A plurality of connectors for receiving a plurality of input cables is positioned within the plurality of openings and is mounted to the bracket. Each of the plurality of connectors includes at least fifteen conductive pins. A plurality of output cables operatively coupled to each of the plurality of connectors is also provided. Each of the plurality of output cables is operatively coupled to a predetermined set of the at least fifteen conductive pins. Each of the plurality of output cables includes an adapter for connection to one of the plurality of electronic modules.

Interface panel apparatus and method

A system for distributing power to a plurality of electronic modules housed within an electronics cabinet includes an electronics cabinet and at least one power filter mounted to the electronics cabinet. At least one electronic module is housed within the electronics cabinet. A first bus bar is positioned within the electronics cabinet for receiving at least one power input cable. A second bus bar is positioned within the electronics cabinet and is electrically connected to the first bus bar and to the power filter. The second bus bar routes input power from the first bus bar to the power filter and routes filtered power to the at least one electronic module.

System and method of distributing power to a plurality of electronic modules housed within an electronics cabinet

An apparatus and method for distributing power includes a housing, at least one input terminal, and at least one output terminal. The input and output terminals are each positioned in the housing. The input terminal is operatively connected to the output terminal. At least one circuit breaker is positioned in the housing. The circuit breaker includes an on position and an off position. The circuit breaker is operatively connected to the input terminal and the output terminal. An alarm circuit is operatively connected to the output terminal to prevent an alarm signal when an electronic chassis is not operatively connected to the output terminal and the circuit breaker is in the off position.
