Responsive to the module 700 being installed in the bay, the solenoid actuator 660 may actuate the engagement mechanism 650 by moving the plunger 662 (movement “a” in FIGS. 3B and 4B). This causes the second link 653 to move towards its engaged position (movement “b” in FIGS. 3B and 4B), which applies a force to the engagement bar 626 that moves it downward in an arc (movement “c” in FIGS. 3B and 4B). This results in the state shown in FIGS. 3C, 4C, and 5B in which the module interface 632 of the cold plate 630 is in contact with the thermal interface 723 of the module 700. Moreover, the second link 653 is in its engaged position, with the distance d3 (less than d2) between the link 653 and the motor 661. In this state, the module 700 may also be locked in the bay 600 by the locking pins 627.
FIGS. 6A-6B illustrate an example sequence of installing a pluggable module 700 in which a rotary electric motor 663 is used as the actuator 660 to actuate the cold plate engagement mechanism 650. The sequence is similar to that described above with reference to FIGS. 3-5. Movement of parts between the figures is shown with dash-lined arrows.
