Abstract
A network device having improved thermal cooling is provided. The network device includes a first printed circuit board (PCB) having a plurality of common connectors and one or more second PCBs, each second PCB coupled to the first PCB by a respective common connector of the plurality of common connectors. Each second PCB may include a set of ports, each port in the set of ports coupled to the respective common connector via the second PCB. The one or more second PCBs may be arranged vertically parallel on a front side of the first PCB such that each second PCB forms a 90 degree angle with the first PCB to allow air to flow in spaces defined between vertically adjacent second PCBs.
