A connector system comprising: a base mount configured to hold a connector module therein; a slider latch received in the base mount and movable in a longitudinal direction, the slider latch having a profiled groove configured to latchably receive a cam of the connector module, the profiled groove comprising inclined surfaces (242, 244, 246) that control movement of the cam along the profiled grove; a faceplate coupled to the base mount, the faceplate having an opening providing access to the slider latch, the base mount being configured to receive the connector module through the opening in the faceplate; an ejector button operatively coupled to the slider latch to move the slider latch from an latched position to an unlatched position, the slider latch being configured to eject the connector module as the slider latch moves between the latched and unlatched positions; and a spring engaging the slider latch, the spring acting on the slider latch in a biasing direction, the spring forcing the slider latch to return to the latched position after the ejector button is released, wherein the profiled groove includes an ejection area where the cam is loaded into the profiled groove, and a latching area in which the cam is captured to secure the connector module; wherein the inclined surfaces comprise a first inclined surface at the ejection area of the profiled grove, and a second inclined surface at the latching area of the profiled groove, the first and second inclined surfaces forming a blocker between the ejection and latching areas, wherein the cam engages the first inclined surface to shift the slider latch from the latched position towards the unlatched position as the connector module is pressed into the base mount in a loading direction, until the cam clears the blocker and the slide latch snaps back to a latched position in which the cam is captured in the latching area; characterised in that the profiled groove further includes a holding area where the cam is not fully ejected, wherein the inclined surfaces comprise a third inclined surface at the holding area of the profiled groove, wherein the third inclined surface engages the cam and drives the cam out of the latching area to the holding area as the ejector button is pressed and the slider latch is moved to the unlatched position, such that the cam clears the blocker and the connector module can be manually pulled out of the base mount. a base mount configured to hold a connector module therein; a slider latch received in the base mount and movable in a longitudinal direction, the slider latch having a profiled groove configured to latchably receive a cam of the connector module, the profiled groove comprising inclined surfaces (242, 244, 246) that control movement of the cam along the profiled grove; a faceplate coupled to the base mount, the faceplate having an opening providing access to the slider latch, the base mount being configured to receive the connector module through the opening in the faceplate; an ejector button operatively coupled to the slider latch to move the slider latch from an latched position to an unlatched position, the slider latch being configured to eject the connector module as the slider latch moves between the latched and unlatched positions; and a spring engaging the slider latch, the spring acting on the slider latch in a biasing direction, the spring forcing the slider latch to return to the latched position after the ejector button is released, wherein the profiled groove includes an ejection area where the cam is loaded into the profiled groove, and a latching area in which the cam is captured to secure the connector module; wherein the inclined surfaces comprise a first inclined surface at the ejection area of the profiled grove, and a second inclined surface at the latching area of the profiled groove, the first and second inclined surfaces forming a blocker between the ejection and latching areas, wherein the cam engages the first inclined surface to shift the slider latch from the latched position towards the unlatched position as the connector module is pressed into the base mount in a loading direction, until the cam clears the blocker and the slide latch snaps back to a latched position in which the cam is captured in the latching area; characterised in that the profiled groove further includes a holding area where the cam is not fully ejected, wherein the inclined surfaces comprise a third inclined surface at the holding area of the profiled groove, wherein the third inclined surface engages the cam and drives the cam out of the latching area to the holding area as the ejector button is pressed and the slider latch is moved to the unlatched position, such that the cam clears the blocker and the connector module can be manually pulled out of the base mount.
