A method for controlling insertion of one or more receptacles into a receptacle tray, the method comprising: instructing, by a processor, a receptacle tray circuit that the one or more receptacles are to be inserted; energizing, by the receptacle tray circuit, a motor of the receptacle tray to drive a latching element of the receptacle tray in order to unlatch the proper locations of the one or more receptacles to be inserted, wherein the receptacle tray circuit energizes the motor, the motor driving a rod in an unlatch direction until a flag interrupts a light beam sensor, at which point the motor is deactivated; activating, by the receptacle tray circuit, one or more placement indicators in the receptacle tray where the one or more receptacles are to be inserted; detecting, by the receptacle tray circuit, when the one or more receptacles are inserted by detecting electrical continuity between one or more connectors of the receptacle tray circuit and respective connectors of the one or more receptacles; deactivating, by the receptacle tray circuit, the activated one or more placement indicators; and transmitting, by the receptacle tray circuit, a message to the processor that the one or more receptacles that are to be inserted have been inserted, wherein each of the one or more receptacles comprises: two or more tangs protruding from a front face of the receptacle closest to the respective connector on the receptacle, wherein the two or more tangs are mated with respective mating units in the receptacle tray; first and second protrusions on a bottom face of the receptacle, the bottom face including one or more hooks for being engaged by the latching element; and one or more ramps, integrated into a back face of the receptacle, the one or more ramps interfaced with one or more back guide features on the receptacle tray, wherein the one or more back guide features provide an initial interaction that pushes the one or more tangs into engagement with the respective mating units. instructing, by a processor, a receptacle tray circuit that the one or more receptacles are to be inserted; energizing, by the receptacle tray circuit, a motor of the receptacle tray to drive a latching element of the receptacle tray in order to unlatch the proper locations of the one or more receptacles to be inserted, wherein the receptacle tray circuit energizes the motor, the motor driving a rod in an unlatch direction until a flag interrupts a light beam sensor, at which point the motor is deactivated; activating, by the receptacle tray circuit, one or more placement indicators in the receptacle tray where the one or more receptacles are to be inserted; detecting, by the receptacle tray circuit, when the one or more receptacles are inserted by detecting electrical continuity between one or more connectors of the receptacle tray circuit and respective connectors of the one or more receptacles; deactivating, by the receptacle tray circuit, the activated one or more placement indicators; and transmitting, by the receptacle tray circuit, a message to the processor that the one or more receptacles that are to be inserted have been inserted, wherein each of the one or more receptacles comprises: two or more tangs protruding from a front face of the receptacle closest to the respective connector on the receptacle, wherein the two or more tangs are mated with respective mating units in the receptacle tray; first and second protrusions on a bottom face of the receptacle, the bottom face including one or more hooks for being engaged by the latching element; and one or more ramps, integrated into a back face of the receptacle, the one or more ramps interfaced with one or more back guide features on the receptacle tray, wherein the one or more back guide features provide an initial interaction that pushes the one or more tangs into engagement with the respective mating units. two or more tangs protruding from a front face of the receptacle closest to the respective connector on the receptacle, wherein the two or more tangs are mated with respective mating units in the receptacle tray; first and second protrusions on a bottom face of the receptacle, the bottom face including one or more hooks for being engaged by the latching element; and one or more ramps, integrated into a back face of the receptacle, the one or more ramps interfaced with one or more back guide features on the receptacle tray, wherein the one or more back guide features provide an initial interaction that pushes the one or more tangs into engagement with the respective mating units.
