Abstract: A port protection device includes a blocking element movement subsystem that may be coupled to a port that defines a port entrance, and a port entrance blocking element connected to the blocking element movement subsystem and defining airflow aperture(s). When the blocking element movement subsystem is coupled to the port, the blocking element movement subsystem allows the port entrance blocking element to be positioned in a port protection orientation immediately adjacent the port entrance such that airflow is restricted to entering the port via the airflow aperture(s). When the blocking element movement subsystem is coupled to the port, the blocking element movement subsystem also allows the port entrance blocking element to move from the port protection orientation to a cable connector orientation in response to engagement with a cable connector so that the cable connector may move through the port entrance to connect to the port.
