A device comprising: a system board having contacts to electrically couple to two first removable transceiver modules or one second removable transceiver module; a cage coupled to the system board over the contacts; a first carrier within the cage and is substantially vertically movable with respect to the cage, the first carrier includes rails for receiving one first transceiver module or a portion of the second transceiver module; a first lever pivotable with respect to the cage and movable to an up position to align one first transceiver module or the second transceiver module with the contacts and to a down position to electrically couple one first transceiver module or the second transceiver module to the contacts; and characterized in that: the first lever is between the cage and the first carrier, and the device further comprising: a second carrier within the cage and movable with respect to the cage, the second carrier includes rails for receiving one first transceiver module or another portion of the second transceiver module; a second lever between the cage and the second carrier, the second lever pivotable with respect to the cage and movable to an up position to align one first transceiver module or the second transceiver module with the contacts and to a down position to electrically couple one first transceiver module or the second transceiver module to the contacts; a first sliding lid to maintain the first lever in the down position and to prevent air flow and EMI/RFI leakage with one first transceiver module or the second transceiver module installed in the first carrier; and a second sliding lid to maintain the second lever in the down position and to prevent air flow and EMI/RFI leakage with one first transceiver module or the second transceiver module installed in the second carrier. a system board having contacts to electrically couple to two first removable transceiver modules or one second removable transceiver module;
