Receptacle cage having emi shielding

A receptacle connector assembly comprising:

• a receptacle cage having shielding walls extending between a front end and a rear end of the receptacle cage, the shielding walls including a top wall, a first side wall extending from the top wall to a bottom of the receptacle cage, and a second side wall extending from the top wall opposite the first side wall to the bottom of the receptacle cage, wherein the top wall, the first side wall and the second side wall form a module channel configured to receive a pluggable module, the front end having a port open to the pluggable module to receive the pluggable module;
• and
• an electromagnetic interference (EMI) shield coupled to the receptacle cage at the front end, the EMI shield having an upper shield member including an upper base coupled to the top wall to electrically connect the EMI shield to the top wall, the upper shield member including upper spring fingers extending from the upper base to distal ends, each upper spring finger including a panel interface configured to engage a panel surrounding the receptacle cage to electrically connect the upper shield member to the panel, the EMI shield including an upper gasket between the receptacle cage and the upper spring fingers, the upper gasket electrically connecting the upper spring fingers, the upper gasket electrically connecting the upper spring fingers to the top wall.
