The electrical engagement lever 734 of the module 700 may then be actuated downward until the module board 721 is the distance d9 (which is less than d8) from the system board 2, as shown by the movement “e” in FIGS. 11A and 12B. This results in the electrical connector 724 of the module 700 connecting with the electrical connector 602. In this state, the cold plate 630 is now the distance d7 (greater than d5) from the thermal interface 723 (see FIG. 12B). Moreover, the actuation of the electrical engagement lever 734 causes the release tabs 738 of the module 700 to move outward, as indicated by the movement “k” in FIG. 13A. This results in the release tabs 738 ceasing to interfere with the curtain tabs 658, as illustrated in FIG. 13B. Thus, the cold plate engagement mechanism 650 may now be actuated. In particular, the lever tab 657 may be rotated downward (movement “f” in FIGS. 11A, 12C, and 13B), and then the lever tab 657 may be pushed horizontally towards the bay 600 (movement “g” in FIGS. 11A, 12C). This causes the second link 653 to move horizontally (movement “h” in FIGS. 11A, 12C), which applies a force to the engagement bar 626 that moves it downward in an arc (movement “i” in FIGS. 11A, 12C). This results in the state shown in FIGS. 11B 12D, and 13C in which the cold plate 630 is in the engaged position and is in contact with the module 700. The module 700 may also be locked in the bay 600 by the locking pins 627 in this state. The clamp 659B may hold the engagement lever 655 in this position, as illustrated in FIG. 13C.
