In some examples in which multiple bays 600 are included, the control circuitry 800 may be configured to actuate the actuators 600 responsive to some user action, such as the user pushing a button (such as the button 750), rather than automatically actuating responsive to the first module 700 being installed. This approach may be beneficial in that it allows for a user to decide how many bays 600 they want to populate with modules 700 before actuating the cold plate engagement mechanism 650. To avoid actuating the engagement mechanism 650 when there are improperly seated modules 700, or modules 700 that are not compatible with the bay 600, some examples may include presence detect sensors (not illustrated), such as optical sensors, magnetic sensors, mechanical sensors, to detect a presence of a module 700 in the bay 600 even if the module 700 is not electrically connected to the connector 602. The control circuitry 800 may then be configured to actuate the actuators 660 only if all of the modules 700 whose presence is detected by the sensors are properly installed in the bay 600, as determined from signals received from the electrical connector 602.
In some examples in which multiple bays 600 are included, the control circuitry 800 may be configured to automatically actuate the actuators 660 responsive to all of the bays 600 having a module 700 installed therein (rather than actuating as soon as one module 700 is installed). This approach may be beneficial in that it reduces the need for user-performed steps.
