Airflow Direction in the PTX10008

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 control boards and line cards, through the switch interface boards (SIBs), and
exits from the fan trays and the power supplies. This airflow is called port-to-FRU cooling or airflow out
(AFO). See Figure 23 on page
