Patent ID: 7566244

Claim:
A circuit board assembly, comprising: a circuit board; a pluggable transceiver module connector constructed and arranged to electrically connect with a pluggable transceiver module including a first end supporting a retention post, the pluggable transceiver module connector being supported on and spaced from the circuit board a sufficient distance to electrically connect with an electrical interface portion disposed on a second end of the pluggable transceiver module, a portion of the second end of the luggable transceiver module extending underneath the electrical interface portion into the space between the circuit board and the connector; and a cage supported by the circuit board, the cage including: a cage body defining (i) a circuit board side which faces the circuit board, (ii) an opposing side which faces away from the circuit board, and (iii) a cavity within which the pluggable transceiver module substantially resides during module operation, the pluggable transceiver module connector being substantially disposed within the cavity, a set of electrical contacts disposed along the circuit board side defined by the cage body, the set of electrical contacts mechanically mounting and electrically connecting the cage body to the circuit board, and a tab constructed and arranged to engage the retention post of the pluggable transceiver module when the pluggable transceiver module substantially resides within the cavity defined by the cage body, the tab residing on the opposing side defined by the cage body and being movable between a position engaged with the retention post and a position disengaged from the retention post.
