Claim 8:
9. A switch card assembly comprising:
a switch printed circuit board (PCB);
at least one switch chip mounted on the Switch PCB;
a plurality of optical module connectors are mounted on the Switch PCB within a periphery of the Switch PCB, each optical module connector (“connector”) having an airflow channel between a first end of the connector and a back end of the connector, wherein an area of the Switch PCB on which the connector is mounted includes a corresponding cutout substantially aligned with the airflow channel at the back end of the connector;
a heat dissipator disposed at the periphery of the Switch PCB; and
the Switch PCB having a plurality of PCB traces that electrically connect the at least one switch chip to the plurality of optical module connectors,
wherein the first ends of the optical module connectors and a first end of the heat dissipator are in spaced apart relation along a plane parallel to the Switch PCB, wherein when the first ends of the optical module connectors and the first end of the heat dissipator are exposed to an ambient airflow, a first portion of the ambient airflow enters the first ends of the optical module connectors, and a second portion of the ambient airflow that is separate from the first portion enters the first end of the heat dissipator.
