A switch system including a plurality of pluggable modules, a plurality of cages housing the plurality of pluggable modules, and a host printed circuit board (PCB). The system is designed to improve airflow around the host PCB to facilitate cooling. The cages may be designed to have airflow openings on a bottom surface thereof (facing towards the host PCB). The pluggable modules may be designed to have a heat sink on an external lower surface (facing towards the host PCB), which may be in the form of external fins. The host PCB may be designed to have cut-outs in a front portion thereof. The cooperation of the, and the airflow openings, heat sinks, and cut-outs create improved airflow for cooling of the host PCB.
