Abstract
The disclosed embodiments include a plurality of plenums for distributing cooling air throughout the switch. The switch is divided into separate cooling domains. Each PCB receives a separate supply of cooling air, so that no PCB is located upstream or downstream from another PCB. The present embodiments thus eliminate the problem of stack rise, which can decrease switch performance.
