A circuit assembly includes a printed circuit board, an integrated circuit chip coupled to the printed circuit board, and a plurality of power phases associated with the integrated circuit chip arranged as grouped power phases. One or more power phases of the grouped power phases is physically distanced from a side of the integrated circuit chip associated with physically distanced power phase(s) of the grouped power phases.

A pluggable module for use in a networking system includes a body with an electrical interface configured to be inserted into networking equipment; a head connected to the body and including a handle; and a light pipe with an entry in or near the body, the light pipe configured to provide light from inside the body to the handle. The body can include a light source directed towards the entry. The light source can be a Light Emitting Diode (LED). Advantageously, this disclosure provides an ability to support status lights in a very small surface area on a pluggable module.

Protection elements are provided for protecting optical networking systems during shipment. In one implementation, a system includes a card having one or more sockets, each socket having a connector device. The system also includes a pluggable module having an interface configured to connect with the connector device of a respective socket when the pluggable module is fully seated in the socket. A first protection element is configured to be held in place near a front edge of the socket. The first protection element is configured to allow the pluggable module to be arranged in a partially inserted position within the socket. Also, the first protection element is further configured to block the pluggable module from being fully seated in the socket to thereby prevent the interface of the pluggable module from contacting the connector device of the socket.

Protection elements used for shipping optical networking equipment

Power supply systems are provided for carrying electrical power from a power source to a circuit board mounted on a housing, shelf, cabinet, etc. for supporting networking equipment. A busbar assembly, according to one embodiment, includes a pair of conductive strips configured to carry electrical power. The pair of conductive strips are arranged on a front-facing surface of a non-conductive vertical substrate. The busbar assembly further includes one or more alignment blocks configured to hold the pair of conductive strips in a fixed position with respect to the non-conductive vertical substrate. Each of the one or more alignment blocks is configured to guide a pair of power connectors of a circuit board for making electrical contact with the pair of conductive strips, while allowing simultaneous mating of signal connectors on the circuit board with signal connectors on the substrate, when the circuit board is being installed in a housing.

Busbar assembly with alignment and touch-proof features for network elements

A system, a shelf, and a high density platform optimize the physical arrangement of cards to maximize cooling effectiveness and line card pitch while minimizing backplane trace lengths between line interface and switch fabric cards. The shelf and system and associated card arrangement supports scaling to a larger, double-size system that maintains the required length of backplane traces for card communications without compromising card cooling. Advantageously, the shelf and system maintains full NEBS compliance through an arrangement supporting full air intake/outtake through a front and/or back of the shelf or system, i.e. no side ventilation, and includes a false front to ensure all cards (switch fabric and line interface cards) are substantially flush with one another.

A recessed connectorized faceplate assembly for connecting multiple cables at the front of an electronics equipment shelf. The recessed connectorized faceplate assembly includes a connectorized faceplate defining the back wall of a cabling volume behind where a standard faceplate would normally be situated. The cabling volume has an aperture admitting cables routed from a cable trough situated between equipment shelves. The front of the cabling volume comprises a hinged faceplate granting access to the cabling volume. Access is via a pivoting panel forming one of the sidewalls. A bridging cable connecting the circuit card containing the faceplate to the backplane allows partial withdrawal of the card while maintaining connections.
