1. A connector system, comprising:
a circuit board;
a plurality of housing mounted on the circuit board, the plurality of housings arranged side by side;
a plurality of cages, each one of the plurality of cages enclosing one of the plurality of housings, each of the cages including
a front face that defines a first port and further including an electromagnetic interference (EMI) gasket that extends around
a perimeter of cage near the front face, wherein the plurality of cages are spaced apart a predetermined distance;

a thermal washer positioned around the plurality of cages, the thermal washer including a front portion and a main portion,
each of the front and main portions including air apertures, the main portion being a first width that is slightly less than
the predetermined distance, the main portion engaging the EMI gasket, and the front portion having a second width that is
slightly greater than the predetermined distance, the front portion engaging the front face so as to prevent, in operation,
the front portion of the thermal washer from being pressed past the front face.
