In one example embodiment, a host device includes a front panel, a bezel assembly, a floating PCB, and two host guides. The front panel defines an opening configured to receive a pluggable module in a plugging direction. The bezel assembly defines an opening configured to align with the front panel opening and to receive the pluggable module, the bezel assembly rigidly secured to the front panel. The host guides are rigidly secured to the floating PCB and are configured to guide the pluggable module when it is plugged into the host device. The host guides and bezel assembly operate together to allow the floating PCB to float with respect to the front panel in the plugging direction while remaining substantially aligned with the front panel in directions normal to the plugging direction.
