Circuit board assembly for a communication system

A circuit board assembly comprising:

• a circuit board having a mounting surface, the circuit board having a mating edge and side edges extending from the mating edge to a rear edge, the circuit board having a board guide feature for locating the circuit board in an equipment rack;
• an electrical connector having a connector housing holding contacts in a contact array, the connector housing having a mating end and a cable end, the mating end configured to be mated with a mating electrical connector in a mating direction, the electrical connector having cables terminated to the contacts and extending from the cable end, the connector housing having a mounting feature, wherein the contacts include mating ends at the mating end of the connector housing, the mating ends having electrical stubs shorter than a dimensional tolerance distance of the circuit board in the equipment rack, wherein the electrical connector includes ground shields at the mating end providing electrical shielding for the contacts, the ground shields configured to be electrically connected to the mating electrical connector;
• and
• a connector mount for locating the electrical connector relative to the circuit board, the connector mount having a bracket coupled to the mounting surface of the circuit board proximate to the mating edge, the connector mount having a biasing member coupled to the bracket and coupled to the mounting feature of the electrical connector, the biasing member being compressible along a compression axis parallel to the mating direction to allow the electrical connector to float in the mating direction relative to the circuit board, the connector mount allowing the electrical connector to move relative to the circuit board during mating with the mating electrical connector.
