Abstract: A pluggable module housing assembly comprises a base at least partially surrounding a socket having an entrance sized and dimensioned to receive a pluggable module. At least one guide extends adjacent to the socket. A heat sink assembly includes a riding heat sink having a module-contacting surface facing the socket, and an actuating assembly coupled to the base and to the riding heat sink. The actuating assembly is configured to move the riding heat sink relative to the base between a deployed position a first distance from the at least one guide, and a stowed position a second distance from the at least one guide, the second distance being greater than the first distance.
