A second example form factor for the pluggable module 700 is illustrated in FIGS. 14-15B (see also FIGS. 11A-13C). This example form factor may be referred to as a hot-pluggable line pod. In this example, the carrier/housing 710 forms a frame around a perimeter of the module board 721, while leaving a bottom of the module board 721 exposed, and the alignment members 711 extend out from the sides of the carrier/housing 710. This example module 700 also includes an electrical engagement mechanism 730, which supports the module board 721 and moves the module board 721 up and down to electrically connect the electrical connector 724 (which is located on a bottom of the module board 721) with the connector 602 (which is located below the module 700 when it is installed in the bay 600).
In the example module 700 of FIGS. 14-15B, the electrical engagement mechanism 730 includes a board support 731 which supports the board 721, an electrical engagement lever 732 which moves the board support 731 up and down, and a latch mechanism 737. The electrical engagement lever 732 includes lever arms 733 that are pivotally connected to the carrier/housing 710 by arm pivots 736. The lever arms 733 are connected to a lever tab 734 at the front of the module 700, such that moving the lever tab 734 causes the lever arms 733 to rotate upwards or downwards. The lever arms 733 are also pivotally connected to the board support 731 by board pivots 735, so that the board support 731 (and hence the module board 721) moves up and down when the lever arms 733 rotate up or down.
