The control circuitry 800 may detect that the module 700 is installed by, for example, monitoring signals of the electrical connector 602. The detection may be out-of-band or in-band. For example, in an out-of-band detection regime, a presence detect pin may be included in the electrical connector 602, and when the control circuitry 800 detects an electrical signal on the presence detect pin this may be treated as an indication that the module 700 is present and installed. As another example, in an in-band detection regime, the control circuitry 800 may monitor signal of the connector 602 that are used for other purposes, like management signals, configuration check signals, authentication signals, etc., and may treat a particular status of such as signal as an indication that the module 700 is present and installed.
As another example, the control circuitry 800 may monitor the output of a mechanical, optical, or magnetic presence sensor (not illustrated), which signals when the module 700 is present. This may have a draw back in that a sensor may detect an improperly seated module 700 or a module 700 that is not compatible with the bay 600 as being present, in which case actuation of the actuators 660 might be undesirable. However, this drawback may be mitigated by using mechanical keying features (e.g., in the alignment members 601 or bay entrance 603) to prevent incompatible modules 700 from being installed, and/or arranging the sensors such that they detect a presence only when a module 700 is fully seated in the bay 600. The sensors may also be used in conjunction with the monitoring of the electrical signals from the connector 602.
