Airflow Direction in the PTX10004

The air intake to cool the chassis is located on the port (line card) side of the chassis. Air flows into the
chassis from the ports in the Routing and Control Boards (RCBs) and line cards, through the Switch Interface
Boards (SIBs), and exits from the fan trays and the power supplies. See
