Abstract: An ejector may be provided. The ejector may comprise a pawl, a trigger, and a handle. The pawl may be configured to rotate relative to a line card about a first axis. The pawl may comprise a pawl concavity. The trigger may be configured to rotate relative to the line card about a second axis. The trigger may comprise a trigger catch and a trigger lever. The trigger catch may be configured to engage the pawl concavity. The handle may be connected to the pawl and configured to rotate relative to the pawl about a third axis. The trigger catch may be configured to engage the pawl concavity to inhibit rotation of the pawl about the first axis. The trigger catch may be configured to disengage the pawl concavity and to allow rotation of the pawl about the first axis.

Abstract: Disclosed are apparatuses including a cable header block with apertures for floating inserts and a cover plate. The cable header block includes an aperture pattern that matches a pattern of connector terminals. The floating inserts fit in the apertures of the cable header block. The cover plate can also include a through-hole pattern that matches the aperture pattern. Also, each of the through-holes can include a first geometric shape larger than a cross-section of a cable terminal end and a second geometric shape adjacent to the first shape that is smaller than the cross-section of the cable terminal end. The cover plate retains the floating inserts within the apertures. Also, the cover plate aligns the first geometric shape over the floating inserts when the fastener is in a first position and aligns the second geometric shape over the floating inserts when the fastener is in a second position.

Abstract: In one embodiment, an apparatus includes a printed circuit board, and a circuit package mounted to the printed circuit board. The circuit package has a thermal pad. A first heat sink structure of the module is associated with the printed circuit board and has a wall defining a contact surface that contacts and thermally couples with the thermal pad. The wall includes at least one aperture there-through. Solder paste is provided between the contact surface and the thermal pad to bond the contact surface to the thermal pad, with the at least one aperture being constructed and arranged to aid in outgassing of the solder paste.

Abstract: In one implementation, an apparatus includes a securing component configured to attach the line card ejector to a chassis of a network communication device, prevent removal of a line card from the chassis when the securing component is in a first configuration, and allow removal of the line card from the chassis when the securing component is in a second configuration. The apparatus also includes an ejection component configured to facilitate insertion and removal of the line card from the chassis of the network communication device. The apparatus further includes a sensor component configured to detect an imminent removal of the line card from the chassis of the network communication device.
