A Method and System for Detecting and Monitoring Position of Ejectors (or Latches) of a Connector in Modern Computer Systems

Disclosed is a method and system for detecting and monitoring the position of ejectors (or latches) of a connector in modern computer systems. Memory module connector includes a small switch under ejector tabs of memory module housing. The switch may be set to toggle between desirable and undesirable connector positions. The desirable position is signaled through an "on" signal of the switch and undesirable position through "off" signal.

Figure 1 illustrates a Push Button Single Pole Single Throw (SPST) switch that is placed under ejector tabs of memory module housing.

Figure 2 illustrates a truth table that is used to define the position of the switch. As shown in Figure 2, "Open" corresponds to connector latch in open or unlock position and "Closed" corresponds to connector latch in fully closed or lock position.

Figure 2

Figure 3 illustrates a memory module connector with ejectors in fully closed position. The arrows in Figure 3 correspond to the location of ejectors on a memory module connector.

Figure 3

The on and off signals of the switch are transmitted to a General Purpose Input Output (GPIO) port from where the signals are sent to a Board Management Controller (BMC), a monitor circuit, or a similar device. The monitoring device may issue a warning when

an undesirable condition is indicated by the switch.

Figure 4 illustrates electrical connection between BMC, GPIO, switch, and connector latch of a circuit to monitor the status of an ejector. As shown...
