Various apparatus are disclosed for lifting heat sinks during insertion of optical modules into transceiver cages (e.g., housings). The apparatus also provide for lifting of the heat sink during removal of the optical modules from the transceiver cages. While the heat sink is lifted during insertion or removal, the heat sink is in contact with the surface of the optical module when the optical module is fully inserted in the transceiver cage. Lifting of the heat sink during insertion and removal of the optical module allows a thermal interface material (TIM) to be placed on the surface of the heat sink in contact with the optical module to improve thermal conduction between the optical module and the heat sink.

An electronic device includes an instrument panel that includes a display opening, where the instrument panel is located in a first plane; a circuit board located inside the electronic device, where the circuit board includes a display device that includes a display area, and where the display area is located in a second plane that is different from the first plane; and a waveguide that couples the display area to the display opening and guides light, and/or an image displayed in the display area, from the display area to the display opening.

A system may include a switchover element configurable to source or sink power from or to an electronic device electrically coupled to the switchover element and a controller in communication with the switchover element. The controller may be configured to determine if the electronic device is healthy. When the electronic device is healthy, the controller may configure the switchover element to deliver power from the electronic device to the system andconfigure the switchover element to provide the power to any unhealthy electronic device electrically coupled to the system.

Sharing redundant power supply modules among physical systems

An exemplary embodiment provides for methods, apparatuses and systems to facilitate the detection of network device failures in a variety of network topologies. This is accomplished by equipping a network device, or other devices used in conjunction with network devices, with a bypass port or network interface, such as a secondary outgoing network traffic communication port. In a normal operating mode, network traffic received at a first network interface or port is forwarded, after processing on the packet processing path of the network device, from a second network interface or port. In one implementation, the second network interface or port and the bypass port or network interface are connected to corresponding interfaces of a router or two routers. When a network device failure occurs network traffic bypasses the packet processing path of the network device and is forwarded from the bypass port or interface.

According to one embodiment of the invention, an apparatus comprises a heat dissipation unit, such as a heat sink, that encases wireless logic in order to completely surround such logic. When adapted as a wireless network device, a casing further encases the heat dissipation unit. The casing includes a plurality of slots that are aligned with heat-radiating elements positioned around the periphery of the heat dissipation unit to allow for cooling by convection.

A reversible fan tray device is provided for a power supply unit. The fan tray device includes a mounting panel to be removably mounted to the power supply, a fan unit secured to the mounting panel to provide airflow through the electronic device, and an interconnection board secured to the mounting panel to provide an electrical connection between the fan unit and the power supply unit. The mounting panel can be positioned in either of two orientations, the first orientation to draw external air into the power supply unit and the second orientation to force internal air out of the power supply unit. The interconnection board mates with a connector on the power supply unit when the fan tray cassette is in either of the two orientations. The interconnection board provides an airflow direction indication to the power supply unit for an existing orientation of the two orientations.

A reversible airflow fan tray assembly is provided for an electronic device. The fan tray assembly includes a face plate to be removably mounted to the electronic device and a fan tray cassette to be removably mounted to the face plate in multiple orientations. The fan tray cassette includes a fan unit to provide airflow through the electronic device, and an interconnection board to provide an electrical connection between the fan unit and the electronic device, where the interconnection board mates with a connector on the electronic device when the fan tray cassette is in any of the multiple orientations. The interconnection board provides an airflow direction indication to the electronic device for a current orientation of the multiple orientations.
