Examples relate to a removable transceiver module that comprises a base frame installable in a rail-pair receptacle that surrounds a first connector in a system board. It further comprises a module base board, a second connector attached thereto and a lever handle pivotally attached to the base frame and coupled to the module base board. The transceiver module is installed in the rail-pair receptacle in response to a lateral movement of the base frame to the receptacle to align the first and second connectors. The lever handle is movable between a closed position to couple the second connector to the first connector and an open position to install the transceiver module into the receptacle. This lever handle determines a vertical move of the module base board between the closed position and the open position.
