A card edge connector includes a contact assembly received in a cavity of a housing having a card slot in a shroud configured to receive a card edge of a module circuit board of a pluggable module. The contact assembly has upper and lower contacts having mating ends. The card edge connector includes upper biasing members at a top wall of the shroud associated with corresponding upper contacts each having an outer biasing surface engaging the pluggable module when mated with the card edge connector and having an inner biasing surface engaging the contact assembly proximate to the corresponding upper contact. The upper biasing member is movable from a released position to a compressed position. The upper biasing member moves the upper contact from an unmated position to a mated position as the upper biasing member is moved from the released position to the compressed position.
