An electrical connector assembly includes a cage member having a plurality of walls comprising side walls and an end wall defining a port configured to receive a pluggable module that is electrically connected to a communication connector housed within the cage member. The port has an airflow channel along the end wall allowing airflow through the port along the pluggable module. Standoff features extend from at least one of the end wall and the side walls. The standoff features extend into the airflow channel and are configured to engage the pluggable module and locate the pluggable module relative to the communication connector for mating thereto and locate the pluggable module relative to the airflow channel.
